n shrub.
The shrubby species is nonsprouting, erect, 0.4 to 2.0 m, with branchlets that become densely haired in the flowering period.
Flowering will occur at a time between July and October, the inflorescence is compacted on racemes, 10 - 14 creamy or white flowers; these arrangements are upright appearing at the now silky terminal branchlets. Pedicel - 2–5 mm long; tepal - 4–6 mm; pistil 5–7 mm.
The leaves are simple, and narrow or obovate; they are thick, glabrous, 20 – 75 mm long, 1.2 – 9 mm wide; flat or nearly circular in cross section. The margin is complete and has a prominent venation; longitudinal veins may be three and are indistinct.
Fruit and seeds will appear on short stalks, and are ovate in form; the fruit is elliptic, 20–37 mm long, 12–20 mm wide, with a slender tip. Seed tending to triangular and is winged - pale brown and darkly striated.
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.

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
