A native rainforest grapevine with a dark reputation. It is called the Bushkiller. I must confess that all the times I have seen it, which would be in Wet eucalypt forest, I never got any impression that this grapevine would smother anything.
The leaves are compound in a foot-like fashion, with 5 leaflets. This species can be confused with Cayratia clematidea, another rather soft fleshy vine species like the Bushkiller. The lowest leaflets of that species however, tend to have a little lobing, and the leaflets are somewhat more pointed.
