About Me

My photo
Canberra-based naturalist, conservationist, educator since 1980. I’m passionate about the natural world (especially the southern hemisphere), and trying to understand it and to share such understandings. To that aim I’ve written several books (most recently 'Birds in Their Habitats' and 'Australian Bird Names; origins and meanings'), and run tours all over Australia, and for 17 years to South and Central America. I've done a lot of ABC radio work, chaired a government environmental advisory committee and taught many adult education classes – and of course presented this blog, since 2012. I am a recipient of the Australian Natural History Medallion, the Australian Plants Award and most recently a Medal of the Order of Australia for ‘services to conservation and the environment’. I live happily in suburban Duffy with my partner Louise surrounded by a dense native garden and lots of birds.

Magnificent Mallee #2: some plants of the mallee

Last time, I offered something of a blogging ode to one of my favourite habitats, the wonderful mallee lands of inland semi-arid Australia. If you missed it you might want to look at it for some background before reading this addendum to it, but if you don't feel like doing that then this post can stand alone - it's really just a photo homage to a range of plants other than the mallee eucalypts themselves that I've encountered and enjoyed over the years across the country. I do notice now that plants from Western and South Australia dominate here, but those states do have a lot of the mallee too! To avoid appearing to be showing favouritism (or actually doing so!), I'm going to offer the poster plants below alphabetically in order of Family (though even that's not simple these days). 

The current trend among plant taxonomists is to lump previous Families into sometimes vast 'super-families'. It's not a matter of right of wrong - the actual relationships don't change - but the question of where to draw the lines between related Families is ultimately a human conceit. But enough of that, the important thing is the plant themselves. The plants I've selected were photographed in mallee habitat, and many of them are mallee specialists. In each family there are other - sometimes many other - mallee species I could have chosen.

It's really pretty much just a photo essay to celebrate some rather lovely plants that you may not be familiar with unless you're another mallee meanderer, in which case I hope it brings some good memories.

ANTHERICACAE
One of several families of Australian lilies; I talked more about them in a series beginning here. I see though that that was a decade ago, so things might have changed again, but I don't think very significantly.
Mangles' Fringe Lily Thysanotus manglesianus, Kalbarri NP, near Geraldton, Western Australia.
It grows widely in the south-west, but especially in the mallee.

ASTERACEAE

The familiar daisy family, which no-one has tried to redefine as far as I know!
Invisible Plant (or Wiry Podolepis) Podolepis capillaris Pinkawillinie Conservation Park,
Eyre Peninsula, South Australia. I love this name and, though it's not
terribly invisible here, the threadlike stems and pale flowers can be hard to
see in some lights. I do have another photo that illustrates this, but then you
wouldn't be able to see much! It does have a wide distribution in sandy
soils in southern and central Australia, but I've mostly seen it in mallee.

Poached Egg Daisy Polycalymma (fomerly Myriocephalus) stuartii,
Hattah-Kulkyne NP, north-western Victoria. Another sand-lover, found
widely in the mallee and beyond.

FABACEAE
The peas, one of the most familiar and largest plant families in the world, at least until the recent conglomerations of families.
Cockies' Tongues Templetonia retusa, Dhilba Guuranda–Innes National Park,
Yorke Peninsula, South Australia. This has always been a favourite of mine, partly
because it really is a striking shrub, and partly because it was one of the first
native plant names I learned. It grows in coastal limestone (and in the Flinders
Ranges), much of which is among mallee.
Granny Bonnets Isotropis cuneifolia, Badgingarra National Park,
south-western Australia. Again the species grows in a variety of sandy
and gravelly habitats (especially soon after fires), but this one was in mallee.
Common Eutaxia or Mallee Bush-Pea Eutaxia microphylla, Wyperfeld NP,
north-western Victoria. Mostly found in the mallee

GOODENIACEAE
The goodenia family in eastern Australia is probably best-known for yellow-flowered herbs and shrubs of Goodenia, and the purple-flowered Dampiera. In Western Australia however the various Lechanaultia species are truly dramatic. It's worth noting that in honouring the splendidly named chief botanist on the mighty Baudin scientific expedition to Australia in 1801, Jean-Baptiste Louis-Claude-Theodore Leschenault de la Tour, the great Scottish botanist Robert Brown, normally so meticulous, misspelt his name. Too late though, once it was published.
Blue Lechenaultia L. biloba, Yandin Hill Lookout, north of Perth.
Here it was growing near another WA special, the amazing
Mottlecah mallee E. macrocarpa. See the previous posting for photos of it.
Red Lechenaultia L. formosa, Stirling Ranges NP, south-western WA.
Sandhill Goodenia G. Goodenia willisiana is a much more modest member of
the family, found in mallee in north-western Victoria and adjacent South Australia
and NSW. Here it is in Wyperfeld NP.
Velvet Dampiera V. marifolia, also in Wyperfeld NP.
This striking plant, abundant on a recent spring trip to the area,
has a similar mallee lands distribution to the previous species.

HALORAGACEAE

A relatively small family, mostly in Australia but also has species spread across much of the world, ranging from aquatic herbs to small trees. No species is likely to be familiar to non-specialists, and this lovely mallee herb is the only one I could readily name.

Golden Pennants Glischrocaryon behrii, Pinkawillinie NP, Eyre Peninsula,
South Australia. It is found in mallee from here east to western Victoria
and south-western NSW. It can grow in extensive golden colonies, and
always brings a smile to my face.

 LAMIACEAE
A much more familiar family, including many garden culinary herbs and well-known native shrubs such as Prostanthera and Westringia.

West Coast Mintbush Prostanthera calycina, High Cliffs, at the southern tip
of Eyre Peninsula. A true mallee specialist, it is endemic to Eyre Peninsula,
growing on limestone outcrops.
Stiff Westringia W. rigida, Nullarbor cliffs, South Australia.
Usually on limestone and in mallee, though it also extends to dry forests from
Western Australia to NSW.
MALVACEAE
This is one of the newly defined 'superfamilies' that I mentioned at the start of this post. Already a large family, Malvaceae (based on hibiscuses and hollyhocks) now has a mind-numbing 4200 or so species, after the 1500 or so species of the family Sterculiacae were moved into it. All four species featured here were previously included in that family.
Pink Velvet Bush Lasiopetalum behrii, Caralue Bluff Conservation Park,
Eyre Peninsula, South Australia. It is found in mallee from
Western Australia to south-western NSW.
Coast Velvet Bush Lasiopetalum discolor, Dhilba Guuranda–Innes National Park,
Yorke Peninsula, South Australia. It grows along much of the south coast,
in Western and South Australia, though also in the Bass Strait and northern Tasmania.
On the mainland it is found primarily in mallee, and on dunes.
Paper Flower Thomasia petalocalyx, growing in mallee in the Coorong NP, South Australia.
It is also found in other habitats along the coast and hinterlands in the
south-west and south-east.
Trailing Commersonia Androcalva (formerly Commersonia) tatei,
Heggaton CP, Eyre Peninsula, South Australia.
An interesting little plant which is almost endemic to the mallee of Eyre Peninsula
- disqualified only by one totally isolated population in far north-western Victoria.
MIMOSACEAE
Yes, I'm going to break my self-imposed rule by not using the official family taxonomy for this one. A little while ago the wattles (ie family Mimosaceae) were lumped in with the already huge pea family Fabaceae to form a mighty megafamily of almost 20,000 species. While wattles are certainly closely related to peas (look at the pods), they form such an obviously distinct and familiar group that I'm going to be pragmatic and look at them separately from the (other) peas. There are of course very many wattles growing in the mallee; here are just three typical species.
Grey Mulga Acacia brachybotrya, Wyperfeld NP, north-west Victoria.
I'm not sure of the significance of the 'mulga' appellation, it certainly doesn't
resemble 'real' Mulga, Acacia aneura. It is an important part of mallee
communities from the edge of the Nullarbor Plain in South Australia
across to Victoria and NSW.
Wallowa Acacia calamifolia, Rudall CP, Eyre Peninsula, South Australia.
A distinctive wattle, it is found throughout the mallee lands of South Australia
and Victoria, and beyond into woodlands of NSW. It is said that its seeds are
important food of Mallee Fowl, but I suspect that this could be said of many
other wattles too.
Sandhill Wattle Acacia ligulata, Gawler Ranges NP, South Australia.
(I learnt it as Chainpod Wattle for its constricted seed pods but in retrospect
I think that this was a descriptive name coined by a clever teacher.)
While it is found in all the mallee lands of Australia, it is also found
far to the north, in every mainland state and the Northern Territory.
 MYRTACEAE
A very familiar family, and of course the one to which the mallee eucalypts themselves belong, but we met some of them last time. Here are three others.
Common Fringe-Myrtle Calytrix tetrogona, Dhilba Guuranda–Innes
National Park, Yorke Peninsula, South Australia. Another plant which,
while found in most of the mallee lands, also grows well beyond them too.
But, far too attractive to be left out!

Black Teatree Melaleuca lanceolata, growing alongside mallee in Coorong NP,
South Australia. It often grows within the mallee itself, and is especially
common near the coast and inland watercourses.
Woolly Featherflower Verticordia monodelpha, Kalbarri NP, central west coast
of Western Australia. This species isn't found far from Kalbarri. The genus is,
in my opinion at least, one of the most glorious in Australia; indeed 'verticordia'
means 'heart-turner'! It is endemic to the west.
ORCHIDACEAE
Well, anyone who knows me will know that I'm not going to miss a chance to allow some orchids to flaunt themselves, and I'm not going to disappoint you! There isn't the variety of orchids in mallee that we find in moister habitats, but here are some good ones to look for.
Long Golden Club Spider Orchid Caladenia (Arachnorchis) aurulenta,
Yeldulknie Conservation Park, Eyre Peninsula, South Australia.
This is a fairly rare species and limited to the northern Eyre Peninsula.
(Of course I could be wrong about this one - there are several quite similar species -
but it seems to meet all the relevant criteria.)
West Wind Spider Orchid Caladenia (Arachnorchis) zephyra, Wanilla Conservation Park,
Eyre Peninsula, South Australia. Apologies for the photo, but it's the only one
I've seen. (Therefore I'm obviously not familiar with it, so again any corrections
would be welcomed.)
Zebra Orchids Caladenia cairnsiana, Stirling Ranges NP.
This is one of the orchids I most look forward to seeing when I go west (not often enough!).
These were growing in mallee but they are also found in a range of habitats.
The same comments about habitat could be made about the Ant or Clown Orchid
Caladenia roei, here in roadside mallee near Hyden, south-west WA.
Tiny Rustyhood Oligochaetochilus pusillus, here in Gawler Ranges NP in South Australia,
is scattered in mallee and open forest across semi-arid southern Austalia.
    
PITTOSPORACEAE
Members of this diverse family, of a couple of hundred species of shrubs, trees and vines, are generally found in moister habitats than the mallee, but one species is very much at home there.
Berrigan or Native Apricot (and many other local names) Pittosporum angustifolium,
Mungo NP, south-western NSW. I am fascinated by its story. Nearly all Pittosporum
species live in east coast rainforest or wet eucalypt forest, but this one adapted as the country
dried out and, instead of retreating with the forests, evolved to the drying conditions.
It is an elegant small tree with weeping foliage found throughout the mallee lands,
and also well beyond to the north.

PROTEACEAE
This is one of the dominant Australian families, an old Gondwanan, found in every Australian habitat. Here is a selection of four, all from different genera (three of them very familiar), which are found in the mallee.
Gland Flower Adenanthos terminalis, Heggaton CP, Eyre Peninsula, South Australia.
It belongs to a genus of over 30 species, all but two of which are endemic to WA.
This species is limited to the mallee lands of South Australia and western Victoria.
Like most of the family it is bird-pollinated.
Fox Banksia B. sphaerocarpa Badgingarra NP, south-western WA.
This low shrub grows in deep sand in mallee, heath and woodlands.
Its dull colours and ground-hugging nature (to hide from birds) suggest that
this flower is one of the many pollinated by native mammals.
Candelabra Grevillea G. candelabroides Kalbarri NP, mid-west coast, WA.
A spectacular grevillea which is restricted to the mallee and heathland
of the northern sandplains in this region.
Emu Tree (I have no idea why, sorry!) Hakea francisiana, Pinkawillinie CP, South Australia.
Most hakeas have fairly small white flowers, so this one is especially impressive.
It grows in mallee and associated heathlands across southern WA and as far
east as Eyre Peninsula (where this one was).

RUTACEAE
A familiar family even if we don't realise it - eg citrus fruit, boronias, correas etc. 

Boronia (also now known as Cyanothamnus) coerulescens, Wanilla Conservation
Park,  Eyre Peninsula, South Australia. This attractive species has flowers ranging
from bright blue (very unusual in Boronias) to greenish to pink to white;
this one appears to be on the bluish end of that spectrum. It is also the only boronia
that I know of that grows in mallee, but there are probably some I don't know
about in the west. It is found in mallee from WA through South Australia
to Victoria. (It was recently determined that Boronia contains more than
one distinct group of species, and 24 of them were moved to Cyanothamnus.)
Desert Phebalium P. bullatum, Gawler Ranges NP, South Australia.
Another mallee specialist, found from the Eyre Peninsula to western Victoria.
The yellow flowers and long stamens are unmistakably Phebalium.
('Desert' in southern Australian plant names is often a codeword for mallee -
see more in the previous posting, and also the next two species.)
SANTALACEAE
The sandalwood family is a widespread one, whose members are all at least partially parasitic on other plants - photosynthesising their own sugars, but pilfering other nutrients, especially from the roots.
Quandong (or Desert or Sweet Quandong, to distinguish it from other related Australian species)
Santalum acuminatum, Nambung NP, south-west WA. Quandongs grow throughout
the mallee lands, but also in woodlands well to the north. There is now quite an
industry (especially around the Flinders Ranges in South Australia) selling jams
and chutneys from the fruit. When I was a child, my grandmother had a cheap
Chinese Checkers set using painted quandong seeds as the moving pieces.
SAPINDACEAE
This is a large world-wide family, best known elsewhere for lychees, maples and horse chestnuts, and in Australia for the native hops, Dodonaea spp. Here there are some 60 species, with another 10 elsewhere in the Southern Hemisphere.
Desert Hop-bush Dodonea stenozyga, near Yalata, eastern end of the Nullarbor Plain,
South Australia. The three-corner papery fruits are typical, but this one is
pretty well limited to the mallee.
SCROPHULARIACEAE
An unlovely name for this large cosmopolitan family. In this post all three members of the family I am introducing are species of (the 'desert lovers', in my Big Three of favourite Australian plant groups, along with orchids and banksias). Previously eremophilas, along with boobiallas (Myoporum) and a small WA genus, comprised the family Myoporaceae, but all have been moved into Scrophulariaceae. All Eremophila are arid-land plants, including the mallee.
Tar Bush Eremophila glabra, here at the eastern end of the Nullarbor Plain in South Australia,
is found right across southern arid and semi-arid Austalia.
Weeooka Eremophila oppositofolia, Whyalla CP, South Australia.
It has a similarly wide distribution to Tar Bush, above.
Scotia Bush Eremophila scoparia, Lake Gilles CP, South Australia.
Again grows very widely across the mallee lands, and into the adjacent Mulga.
And I'm sure you'll agree that that's probably enough for today! If you're really not that interested in Australian wildflowers you'll have given up reading this long ago, so I don't really know why I'm addressing you... :-) If you are still here, thank you and I hope you've enjoyed this floral display that the mallee has produced. I'll be back once more with some more mallee delights, this time some animals. I hope you'll come back then.

The Magnificent Mallee; long despised, finally treasured. #1

 This is a topic close to my heart. I grew up in South Australia, and Adelaide is nearer to
remaining mallee than any other state capital (with the possible exception of Melbourne).
Dad loved it, and I spent time in the mallee long before I encountered any real forests,
let alone wet ones. It seems strange then that it has taken me this long to tackle it
here, but maybe I've never felt ready to do it justice. Such excuses however can lead to us
to never doing anything worthwhile so, prompted by a recent camping trip to
north-western Victoria, here's my tribute to a uniquely Australian habitat.

"No-one knows who made the mallee, but the devil is strongly suspected", at least according to an anonymous writer in The Bulletin in 1901. 

Mallee to the horizon from Warepil Lookout in Hattah-Kulkyne National Park,
north-western Victoria.

The Bulletin disparager came from a long line of whitefella mallee-bashers. Surveyor-General John Oxley (admittedly pretty much always a glass-three-quarters-empty character, judging by his journals), wrote of the mallee country along the Cocoparra Range in south-western NSW in 1817 as "country of the most miserable description... abandoned by every living creature capable of getting out of there". (The local people were understandably uninterested in making his acquaintance.) Others wrote similarly. Later reports however revealed the real reason for the general antipathy. Charles Sturt in 1833, the first to enter the vast South Australian-Victoria mallee lands, of which Hattah-Kulkyne above is but a remnant, described it as "barren and unproductive as the worst of the country we have passed through". An 1851 report to the Victorian Government Surveyor reported that "throughout the whole of the scrub there is neither stone nor timber fit for any useful purpose". The crime of this lovely, subtle and uniquely Australian landscape was that it wasn't apparently 'useful', so there was no point to it. 

Sandhill Wattle Acacia ligulata flowering in mallee in Wyperfeld NP, north-western Victoria.

Nor was this attitude limited to the 19th century by any means. The term 'desert' was applied to the spectacularly rich and highly floral mallee heath country of eastern South Australia and western Victoria - the Ninety Mile Desert in SA, Big and Little Deserts in Victoria. Now, I love the desert lands, but there was no affection in these labels. They couldn't grow wheat or wool, so were effectively sterile.

But there were mallee farmers, and they were tough. Low rainfall, low soil nutrients (ie by European farming standards) and the incredible resilience of the mallee eucalypts, which resprouted from massive underground lignotubers (of which more in a moment) immediately after clearing, made the farmers' lives hell. Moreover the lignotubers ('mallee roots') simply broke their ploughs. In time though ingenuity, technology and science proved too much for even the ancient mallee habitats. Mulleinising in the 1870s meant clearing the bush by dragging water tanks on chains between horses (later tractors), then burning, rough planting and again burning the stubble to knock the regrowth back again. Taller wheat strains just kept their heads above the regenerating scrub. About this time too a Mr Smith of Maitland on South Australia's Yorke Peninsula invented the 'stump jump plough' so that it wasn't necessary to grub out all of the stumps. The invention of superphosphate at Roseworthy College north of Adelaide in the 1880s allowed continuous cropping to assist in controlling regeneration. After this over a million hectares of mallee in the higher rainfall, sandy loam soils north of Adelaide, on the Yorke Peninsula (where almost no original vegetation now remains) and in Western Victoria, were rapidly cleared. 

Millions of hectares more followed in the periods after both world wars, in western NSW, the far north-west of Victoria, Eyre Peninsula and out towards the Nullarbor, and in the south-west of WA. The pace slowed though as erosion issues and soil degradation followed, though the discovery of the role played by missing trace elements (especially cobalt and copper) triggered another burst in the 1950s and 60s. Ironically the Ninety Mile Desert was now redubbed Coonalpyn Downs... It wasn't until the 1970s that mallee conservation became something to consider.

So, perhaps belatedly on my part, what is 'the mallee'?

This map (courtesy of the Australian National Botanic Gardens) gives an indication of
the current (green) and estimated former (pink) distribution of mallee woodlands,
mostly in the semi-arid 200 - 550mm rainfall zone. However we should note that the
current range by no means implies continuous or undamaged mallee.
Most is fragmentary, and what remains doesn't reflect the
original diversity of the different mallee habitats.
The word apparently echoes one used by people in western Victoria to describe the multi-stemmed habit of eucalypts that grow in these low rainfall, low nutrient regions.
Mallee form, Mungo National Park, western NSW.
This form comprises a massive underground lignotuber (ie literally a woody tuber), a 'mallee root' up to a metre in diameter from which grow several equal-sized 'stems' which are actually branches. The foliage grows only at the tips of these branches. The key trigger appears to be low phosphate levels; it seems that low soil phosphate levels inhibit the cell growth which would otherwise lead to stem or leaf formation, and diverts it to carbohydrate production which is converted to wall material in the lignotuber. The lignotuber thus holds considerable nutrient reserves (but not water, despite a much-repeated myth). Roots grow from the lignotuber and these may hold water, a fact which was of course well known to Indigenous people. The lignotuber confers a remarkable resiliency, as the mallee farmers discovered. In a 1920s experiment scientists defoliated one-year-old seedlings 26 times in succession before they, not the eucalypt, gave up the battle.
The top of a large lignotuber protruding from the ground, with the branches growing
up from it. Hattah-Kulkyne National Park.
Some 130 species of eucalypts grow as mallees. However, only about 20 of these always grow thus; the other 130 surprisingly adopt the form only if the conditions - especially the low-phosphate soils - require it. Lignotubers are known in other plant groups elsewhere in the world, but what is unique to Australia is the ability of these species to adopt a mallee form only if the conditions are right. I have stood on dunes in the south-east of South Australia among mallee Pink Gums E. fasciculosa, and looked out at tall single-stemmed trees of the same species growing in the deep soil of the paddocks. This was before digital camera days I'm afraid, but here's another example.
Gum-barked Coolabah (though it has several names across its broad inland distribution)
E. intertexta, near Cobar, western NSW.
The same species growing as a mallee at Redbank Gorge,
western Tjoritja (MacDonnell Ranges) National Park.
This raises another point too; that mallee eucalypts can be found well outside of the area designated on the map above, provided of course that the soil conditions are right.
Port Jackson Mallee E. obstans, Currarong, north end of Jervis Bay, south coast NSW.
This mallee grows in sand and sandstone along the coast from here to Sydney.

Blue Mountains Mallee Ash E. stricta, Blackheath, Blue Mountains, NSW.
This one too, well out of the mallee zone, grows on shallow sandy soils on ridges.
And this in turn leads us the secondary use of the term 'mallee', which I have more than hinted at already. Almost inevitably the habitat that produced the mallee tree's unique form became in time known as simply 'the mallee'. But in this sense too there is not just one uniform 'mallee'. The model may have been updated since, but in Victoria back in the 1990s there were 31 major communities and some 100 vegetation sub-communities recognised. However for our purposes I'm going to look at just three basic mallee habitat 'types', defined by their dominant understorey (though course nature is never interested in being put in our boxes, so it's not always so clear cut).

Mallee-Heath, as the name suggests, has an understorey of heathy shrubs (banksias, hakeas, grevilleas, casuarinas and callitris for example) and grows in deep sand in higher rainfall areas of the zone. For this reason it was one of the first regions of the mallee zone to be cleared for agriculture. Here are a couple of surviving examples.

Sand Stringybark E. arenacea, Little Desert NP, north-western Victoria.
(This species was, until 1988, included with the more widespread Brown Stringybark, E. baxteri.)

Yalata Mallee E. yalatensis, Nullarbor Plain, South Australia.
This very attractive mallee is found around the fringes of the Nullarbor
and, curiously, in an isolated population far to the east near Mannum,
on the Murray River in South Australia.
Mallee with a sparse heathy understorey (with also some saltbush I think),
Gawler Rangers NP, north of the Eyre Peninsula, South Australia.
Fire in Mallee-Heath (as well as the following Mallee-Spinifex) is especially ferocious. All above ground vegetation is burnt and the volatile oils burn in great gas flares above the vegetation. Regeneration though is probably the most rapid of any tree formation in the world. A new stem cluster appears immediately, growing far faster than in other situations because of added potash in the soil, the resources in the lignotuber and reduced root competition for nutrients.
Regenerating burnt mallee, Gluepot Reserve, north of the River Murray in South Australia.
(Actually this was not at all the fiercest mallee fire, as the dead stems are still standing,
though most other plants have gone.)
Mallee-Spinifex also grows on deep sands but in lower rainfall areas. Spinifex refers to various species of the very prickly hummock grass Triodia spp., also known as Porcupine Grass, which forms very important animal habitat, especially for reptiles and invertebrates, but also small birds and mammals. Beyond the mallee, spinifex dominates some 25% of the Australian land area. Here are examples of Mallee-Spinifex from five different states and territories!
Sharp-capped Mallee Eucalyptus oxymitra in harsh gravel on exposed hillsides at the
start of the Ormiston Pound walk, western Tjoritja (MacDonnell Ranges) NP,
central Australia in the Northern Territory.
Normanton Box Eucalyptus normantonensis growing as a mallee form over
spinifex by the excellent dinosaur museum at Lark Quarry, central Queensland.
Mallee with a dense spinifex ground cover, Mungo National Park, south-western NSW.
Thick-leaved Mallee E. pachyphylla growing in a sandy spinifex plain,
Great Sandy Desert, central eastern Western Australia.
Huge (ie long unburnt) spinifex hummock in mallee, Wyperfeld NP, north-western Victoria.
The third broad mallee type is Mallee-Chenopod, ie various species of saltbushes, bluebushes, samphires etc. This is in low rainfall situations where the soil is sandy-clay. For some reason I find this habitat especially aesthetic.
Mallee with a bluebush (Maireana spp.) understorey, Red Banks Conservation Park,
mid-north South Australia.

Late afternoon over mallee-bluebush at Caiguna, west of the Nullarbor Plain
in south-eastern Western Australia.

Samphire (probably Tecticornia spp.) growing on a clay pan in mallee-bluebush
near Normantion, central southern Western Australia.
And I'm going to end this first instalment of a short series with some portraits of mallee species which I (totally subjectively) find particularly pleasing and/or interesting.
Blue-leaved Mallee E. gamophylla, Plenty Highway, central eastern
Northern Territory. The striking blueish rounded leaves are
juvenile leaves which remain in that form. It is found in sandy
country mostly dominated by spinifex.
Curly Mallee E. gillii has similar foliage. It grows in just two areas of
inland ranges; in the Barrier Range near Broken Hill,
in far western NSW (above) and in the Northern Flinders Ranges
of South Australia (at Weetootla Gorge below).

 Port Lincoln Mallee E. albopurpurea, Coffins Bay, South Australia.
This lovely mallee is found only here at the tip of Eyre Peninsula and on
Kangaroo Island. It was formerly regarded as a subspecies of E. landsdowneana
from the Gawler Ranges to the north.
Bushy Yate E. lehmanii, Cape Le Grande NP, in the east of south-western WA.
A spectacular mallee from Albany eastwards as far as Israelite Bay in hill country and dunes.
Mottlecah E. macrocarpa (above and below), Yandin Hill Lookout,
north of Perth, WA. Its flowers are possibly the most dramatic of all eucalypt flowers,
and can be up to 10cm across.

Red, Oil or Acorn Mallee E. oleosa has one of the most extensive distributions of
any mallee species, found from the south-west of WA to eastern Victoria. It flowers
profusely and its leaves were formerly harvested for their high oil content.
Here it is growing on the eastern fringe of the Nullarbor Plain.
Thick-leaved Mallee E. pachyphylla, here deep in the Great Sandy Desert of
central eastern WA though it is found widely in central Australia.
Moort E. platypus, Ravensthorpe, south-west WA. The name means 'flat or broad foot',
for the oddly shaped buds. It grows only along this section of coastline.
Bell-fruit Mallee E. preissiana, Stirling Ranges, south-west WA.
So, the first part of my ode to the marvellous mallee. I hope you've stuck with me through it, and that it has either aroused some good memories of your own, or perhaps sparked some curiosity in a habitat that you may not be familiar with. I'll be looking at some other plants and some animals of the mallee in forthcoming posts - not sure yet if it will two or three parts in all. Hope to join you then, and thanks for coming this far into the mallee with me.
