Vulpia microstachys is a species of grass known by the common names small fescue and small sixweeks grass.

It is native to western North America from British Columbia to Colorado and New Mexico to Baja California, where it grows in many types of open habitat, including grasslands.

It is dominant on some grasslands of California, and it was probably an abundant native grass before the habitat was altered by invasive non-native grasses.

The inflorescence has several open branches bearing clusters of purple-tinged spikelets.

[1] There are four varieties which are sometimes difficult to tell apart; they are separated on the basis of the arrangement and amount of hairs on the spikelets.
