Ostrearia australiana (Hamamelidaceae)

Ostrearia australiana

Making an acquaintance with Ostrearia australiana marks for me the meeting of the third and last member of the three species of Hamamelidaceae in FNQ. This one is probably one of the most nondescript. It does not have very visible stipules like Neostrearia and Noahdendron. There is however, a small stipular scar that forms a small brown ridge around the stems at each leaf axil. The leaves, particularly developing ones, have stellate hairs on the upper surface.

The developing flowers look like green galls on the flowering spikes.

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"!
