Range and habitat

It is native to the Southwestern United States, California, and northern to central Mexico, where it grows in dry regions such as deserts.

Growth pattern

It is a perennial bunchgrass forming small tufts just a few centimeters high with clumps of short, sharp-pointed leaves. The tufts are often enveloped in masses of cottony fibers; these are actually hairlike strands of excreted and evaporated mineral salts.[1]

Stems and leaves

The leaves produce soft, cob-webby hairs that dissolve in water, after summer rains.[3] The hairs are typically not present in spring.[3] Numerous hairless, wiry, stems are 2–5 inches (5–13 cm) tall.[3]

Inflorescence

The hairy inflorescence is a spikelet on the end of the stem, surrounded by a bundle of bractlike leaves, and is 1/4" to 1/2" long.[3] The spikelets which are pale in color, sometimes striped with red, purple, or green. It blooms from February to May.[3]
