Gomphandra australiana (Stemonuraceae)

Gomphandra australiana

There are some plants in Far North Queensland that are indications of the spread of certain plant families from southeast Asian into Australia, ie they indicate a close relationship between the Australian tropics and the Malesian tropics (a botanical region that includes many southeast Asian countries). Gomphandra australiana is one such plant. I found Melanie Schori’s recent thesis on a revision of Gomphandra and it comfirms G. australiana to be the only representative of the genus in Australia while the stronghold of the genus remains in southeast Asia. There has also been some changes in the family level taxonomy. Previously G. australiana was placed in a family known as the Icacinaceae, a little known tropical family of plants. Now it is placed in the Stemonuraceae in which also belongs the FNQ endemic tree Irvingbaileya australis.

There is not very much that is easy to use to distinguish G. australiana when not in flower or fruit. Perhaps the few but strong veins which form loops towards the edge of the lamina might be a good character. But for me anyways, it brings Southeast Asia into the wet tropics of Australia!

These flowers seem to just consist of 5 stamens!

About David Tng

I am David Tng, a hedonistic botanizer who pursues plants with a fervour. I chase the opportunity to delve into various aspects of the study of plants. I have spent untold hours staring at mosses and allied plants, taking picture of pollen, culturing orchids in clean cabinets, counting tree rings, monitoring plant flowering times, etc. I am currently engrossed in the study of plant ecology (a grand excuse to see 'anything I can). Sometimes I think of myself as a shadow taxonomist, a sentimental ecologist, and a spiritual environmentalist - but at the very root of it all, a "plant whisperer"!
