Distribution
It is widely distributed especially to a corridor of the eastern regions of the southwest botanical province, from the Esperance Plains to the northern biogeographic regions. Stony, gravelly loams or sands, particularly laterite sands. It also extends into the Eremaean province, and to the region around the Swan River - it is from here that the name was derived, cygna for Swan.
Subspecies
There are currently two subspecies:
widespread, the entire population excepting that below. It is of Least Concern, at least with regard to extinction.
the leaves might be narrower, needle-like; pistils, tepals slightly shorter. It is found in a small population near Lake King in the Esperance Plains region. The conservation status is that of a threatened, though poorly known species.
