(''Poa fendleriana''. ) In: Fire Effects Information System, (). U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory.〕 ==Description== This species is a perennial grass with small rhizomes. The stems grow up to 70 centimeters tall.〔 The dead sheath bases remain on the plant for a long time.〔 The narrow panicle has up to 8 erect branches crowded with spikelets. One inflorescence may have over 100 spikelets. The plant is dioecious, with male and female flowers on separate plants. Some populations lack male plants, while others are able to reproduce sexually.〔 Asexual reproduction is more common than sexual, and most populations are all female. These produce seed without fertilization by pollen. The sexually reproducing populations are usually found in warmer climates with summer precipitation, while the all-female populations can tolerate colder climates and a wider range of elevations.〔
