Lathyrus angulatus (Australia) ?
abaceae week-14-flora Australia.: Pl confirm Swainsona sp or Mirbelia speciosa.
I think the posted plant is more close to Mirbelia.
Another thread on the same plant with different suggested name as: A weed, Lathyrus angulatus or vicia sativa pl confirm:
A reply from ... in another thread:
"-the plant is Lathyrus angulatus and not swainsona or Mirbelia,
however experts may pl confirm."
