Species: Muhlenbergia poteri

Description:
Bush muhly is a perennial grass that is 25 to 80cm (10 to 31in) tall. The round stems are stiff and wiry with many branches. The stems have Joints or nodes that are 1.5 to 6cm (0.5 to 2.4in) apart.

Geographic Range:
Bush muhly is found from southern California east to west Texas, and from Colorado south to central Mexico. In New Mexico it is found in the southern third of the state extending north up the central counties.

Habitat:
Bush muhly is found on gravelly slopes, brushy flats, and along arroyos. These plants are especially common around and under desert shrubs, giving this grass its common name.

Reproduction and Development:
The flowers bloom from July through October at the end of a many-branched purple flower arrangement called a panicle. A single flower is present in each spikelet that is widely spaced on the branches. The lemmas are 3 to 4mm (0.2 to 0.3in) long with a 5 to 10mm hair-like structure at the end called an awl. The wind is the pollination agent.
