I found this moderately robust non-native creeper in a patch of open woodland. Elsewhere, this climber is known as the Perennial Horsegram and it was probably introduced to Australia as a forage crop. Introduced or not, I find the somewhat green-yellow flowers with a pink splotch to be very attractive.
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"!
