Eriocoma lemmonii is a species of grass known by the common name Lemmon's needlegrass. It is native to western North America, where its distribution extends from British Columbia to southern California.[2][3]

This perennial grass forms a dense clump of stems up to 90 centimetres (35 in) tall. It may be hairless, hairy, or woolly. The inflorescence is a panicle up to 21 centimetres (8.3 in) long by 1 centimeter wide. The spikelets may be over 1 centimetre (0.39 in) long. The awns are up to 3 centimetres (1.2 in) long.[2]

This is a very drought-tolerant grass that can be found in dry areas, such as sunny grasslands and savannas. It can also grow in relatively low-fertility soils. The subspecies pubescens is a serpentine soils endemic.[4]
