Family: Poaceae (Gramineae)View DescriptionDichotomous Key

Common Name: GRASS FAMILY
Habit: Annual to woody perennial herb; roots generally fibrous. Stem: generally round, hollow; nodes swollen, solid. Leaf: alternate, 2-ranked, generally linear, parallel-veined; sheath generally open; ligule membranous or hairy, at blade base. Inflorescence: various (of generally many spikelets). Spikelet: glumes generally 2; florets (lemma, palea, flower) 1--many; lemma generally membranous, sometimes glume-like; palea generally +- transparent, +- enclosed by lemma. Flower: generally bisexual, minute; perianth vestigial; stamens generally 3; stigmas generally 2, generally plumose. Fruit: grain, sometimes achene- or utricle-like.
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. Achnatherum, Ampelodesmos, Hesperostipa, Nassella, Piptatherum, Piptochaetium, Ptilagrostis moved to Stipa; Elytrigia, Leymus, Pascopyrum, Pseudoroegneria, Taeniatherum to Elymus; Hierochloe to Anthoxanthum; Lolium, Vulpia to Festuca; Lycurus to Muhlenbergia; Monanthochloe to Distichlis; Pleuraphis to Hilaria; Rhynchelytrum to Melinis.

Genus: BlepharidachneView Description 

Common Name: EYELASH GRASS, DESERT GRASS
Habit: (Annual) perennial herb, cespitose, often mat-forming. Stem: 3--8(20) cm, often rooting at lower nodes. Leaf: short, clustered at base of shoots; ligules of hairs or 0; blade linear, needle-like to triangular. Inflorescence: panicle-like, dense, short, scarcely elevated above leaves. Spikelet: laterally compressed; glumes +- equal, thin, 1-veined, awn-tipped or awn 0; axis breaking apart above glumes, falling as 1 unit; florets 4, lower 2 sterile or staminate, 3rd bisexual or pistillate; lemma hairy on margins and at base, back rounded, 3-veined, deeply 3-lobed to middle, 1 or both margins ciliate, short-awned, tip awned between lobes, awn = lobes, uppermost floret rudimentary, 3-awned, awns hairy; palea ciliate or glabrous.
Species In Genus: 4 species: southwestern United States, Mexico, Argentina. Etymology: (Greek: eyelash + chaff, referring to ciliate lemma) Note: Similar to Dasyochloa pulchella.
