This member of the Dioscoreaceae
given this name by Christian Gottfried Daniel Nees von Esenbeck in
1846. It is found in southern part of western Australia, growing in a rich soil of a
gravel mix with some to lots of water and some to lots of sun. The size
of the caudex are unknown to me (I started growing one to find out), the vines can reach two or even
three metres. The flowers are bright yellow.
The name refers to the shape
of the leaves, hastifolia is the Latin words hasta, meaning
spear, and folium, meaning leaf.
