Deyeuxia drummondii, Family Poaceae, also known as DrummondÕs Grass, is a smooth, densely
tufted perennial grass growing up to 25 cm tall. It has flat, soft, and fairly smooth green leaves,
up to 5 mm wide and 8 cm long. The leaf sheath is smooth with a membranous ligule, 2Ð3 mm
long with a lacerated apex. There are approximately 30Ð40 inflorescences per plant and each
inflorescence is a dense and spike-like purple head, 20Ð70 mm long, held on a long stem which
enables it to protrude beyond the leaves. The spikelets, 5Ð8 mm long, are solitary and hold a
single flower that bears a slightly projecting bristle (awn) with bisexual florets. Flowering occurs
from December to January. Deyeuxia drummondii is smaller in stature than other native Western
Australian grasses, with the lemma only half as long as the lower glume (Robinson & Coates,
1995; Brown et al., 1998).
