Recently I posted on Kata Tjuta in the central deserts, one of the special places of Australia. I promised to revisit there before the end of September to introduce some of the animals and plants I've come across among and around the great domes. Inevitably there are more plants than animals, not least because of the numbers of visitors much of the time, and because many desert animals are nocturnal, preferring to shelter during the hot dry days. Here is a brief array however to start with.
Mud Dauber wasp, family Sphecidae; like many animals, this one was attracted to water dripping from a tank provided for walkers. |
One of the many dry country cockroaches. |
A bug - ie a Hemipteran - sucking sap with its proboscis inserted into the shrub's 'veins'. |
Brooks' Ctenotus Ctenotus brooksi (and bonus beetle - for the skink anyway). This skink, rusty to match the iron-rich desert sands, is found from the centre across the western deserts. |
Which brings us to the plants of the domes, and fortunately I can offer you a few more of them than of animals. They're in no particular order - I hope you can just enjoy them!
Kata Tjuta Wattle Acacia olgana (above and below) forms thickets in the gorges; it is also found in ranges in the nearby north-west of South Australia. The scientific name comes from the former name Mount Olga for Kata Tjuta, applied in colonial times. (See previous Kata Tjuta post.) |
Acacia inaequilatera, named for the phyllodes which are unevenly divided by the central vein. |
Rulingia (or Androcalva) loxophylla, family Malvaceae. In wet years hundreds of kilometres of outback roads can be lined with this plant. |
Goodenia cycloptera (I am almost sure of the species, but it is variable and there are several similar ones). |
Olearia ferressii, a daisy of sheltered gorges of the central Australian ranges. |
Corkwood Hakea lorea, family Proteaceae. This small tree is found widely across central and northern Australia. |
Honeysuckle Grevillea, G. juncifolia.A particularly lovely grevillea, also found across much of the drier parts of the country. |
Showy Indigo Indigofera basedowii, a shrubby pea which favours the shelter of gorges in the central desert ranges. |
Fanflower Scaevola parvifolia, family Goodeniaceae, in Walpa Gorge. |
Desert Heath Myrtle Aluta (formerly Thryptomene) maisonneuvei, a tough inhabitant of exposed red sand dunes in the central and western deserts. |
Crimson Foxtails or Silver Tails Ptilotus sessilifolius family Amaranthaceae. One of many species of Ptilotus found across the inland, which can dominate entire landscapes after rain. |
Desert Lantern Flower Abutilon leucopetalum family Malvaceae. And yes I know the name means 'white petals', but I didn't name it! Actually flowers can be white or yellow. |
Butterbush or Berrigan (and many other names across the country) Pittosporum angustifolium (formerly P. phillyreoides), a widespread inland tree whose closest relations are in east coast rainforest. |
Hopefully this celebration of life among the domes has given you another reason to visit Kata Tjuta soon - there are certainly plenty of reasons to do so!

You mention that Acacia inaequilatera has phyllodes unevenly divided by the central vein. I think the same applies to Eucalyptus obliqua. As it is seized upon for the specific name I assume it is rather unusual attribute. Is there a known advantage to the plant from this "trick"?

You're right about E. obliqua, also locsally Acacia obliquinervia. Your question is, as ever, an excellent one. It is hard to imagine that it could be an advantage per se (inter alia we'd expect it to be a lot more common if so); I think there are probably more situations than we realise where such a character, neutral in itself, is genetically linked to another which is selected for. (See a discussion on European owl colour morphs changing with rising temps in an upcoming book!)
ReplyDeleteHi Ian, I'm Jack from the Aussie Bird Count (being held 23-29 Oct during National Bird Week) and I wondered if you might share some birds you have seen across Australia ... or perhaps those that you count during the Aussie Bird Count on your blog. Would be great if you could contact me on birdweek@thecword.com.au - Cheers, Jack
