[edit] Distribution
It is endemic to the Central Valley of California, where it grows in vernal pools. This rare grass is a federally listed threatened species in the United States.
[edit] Description
Colusa grass is a clumping bunchgrass with distinctive cylindrical inflorescences covered in flat spikelets. The inflorescences are said to resemble tiny ears of corn. They fruit in grains covered in a gluey secretion, and when a plant is mature each clump becomes brown and sticky with the exudate. The genus was named for the botanist Otto Stapf.
The plant is limited to vernal pool habitat, a type of ecosystem which is increasingly rare as land is consumed by development and agriculture, and damaged by flood control regimes and other alteration in hydrology.[1]
