Genera In Family: 650--900 genera; +- 10550 species: worldwide; greatest economic importance of any family (wheat, rice, maize, millet, sorghum, sugar cane, forage crops, ornamental, weeds; thatching, weaving, building materials). Note: Generally wind-pollinated.

Dasyochloa
Species In Genus: 1 sp. Etymology: (Greek: thick with hair and grass) Unabridged Note: Dasyochloa has been included in Triodia, Tridens, and Erioneuron. It resembles Munroa, in its bracteate inflorescence (Caro 1981). Seedlings of Dasyochloa, as in those of Erioneuron, are shaggy-white-villous. These "hairs" are composed of hair-like, water-soluble crystals, a product of transpiration, which wash off in water.Jepson eFlora Author: Jesús Valdés-Reyna Reference: Valdés-Reyna 2003 FNANM 25:45--48 Unabridged Reference: Caro 1981 Dominguezia 2:1--17; Sanchez 1983 Lilloa 36:131--138; Valdés-Reyna & Hatch 1997 Sida 17:645--666Index of California Plant Names (ICPN; linked via the Jepson Online Interchange)
