Distribution
Neostapfia colusana is endemic to the Central Valley of California, in the northern section's Sacramento Valley and in the southern section's San Joaquin Valley.[1] The bunchgrass grows in vernal pools, which are seasonal shallow freshwater ponds.
It is native to the Central Valley counties of Glenn, Colusa, Yolo, Solano, Stanislaus, and Merced.[7][8]
This rare grass is a federally listed threatened species in the United States.[9][3]
Description
Neostapfia colusana 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.
Conservation
The plant is limited to vernal pool habitats, a type of ecosystem which is increasingly rare as Central Valley land is consumed by development and agriculture, and damaged by flood control regimes and other alterations of hydrology.[10]
