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: DasyochloaView Description 

Common Name: FLUFF GRASS

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.

Dasyochloa pulchella (Kunth) Willd. ex Rydb.
NATIVE
Habit: Perennial herb, stoloniferous or mat-forming. Stem: generally 4--10 cm, scabrous or puberulent, initially erect, becoming bent, rooting at base of inflorescence. Leaf: not basal; sheath with a tuft of hairs at throat, < 2 mm; ligule of hairs 3--5 mm; blade 2--6 cm, folded. Inflorescence: panicle 1--2.5 cm, 1--1.5 cm wide, terminal, short, dense, branches spike-like, bearing 2--4 subsessile to short-pedicelled spikelets, subtended by leafy bracts, densely white-pubescent, light-green or purple-tinged. Spikelet: generally 6--9 mm, laterally compressed, florets (4)6--10; axis breaking above glumes; glumes 6--9 mm, subequal to adjacent lemma, glabrous, 1-veined, short-awned to mucronate; florets bisexual; lemma 3--5.5 mm, densely long-hairy below and on margins, thinly membranous, 3-veined, 2-lobed to +- 1/2, obtuse, midvein extending into a straight awn; palea 2--3.5 mm; anthers 3. Chromosomes: 2n=16.
