Description

Family Poaceae

Annual or perennial herbs, or tall woody bamboos . Flowering stems (culms ) jointed , internodes hollow or solid; branches arising singly from nodes and subtended by a leaf sheath and 2-keeled prophyll, often fascicled in bamboos. Leaves arranged alternately in 2 ranks , differentiated into sheath, blade , and an adaxial erect appendage at sheath/blade junction (ligule) ; leaf sheath surrounding and supporting culm-internode, split to base or infrequently tubular with partially or completely fused margins , modified with reduced blade in bamboos (culm sheaths) ; leaf blades divergent, usually long, narrow and flat, but varying from inrolled and filiform to ovate , veins parallel, sometimes with cross-connecting veinlets (especially in bamboos) ; ligule membranous or a line of hairs . Inflorescence terminal or axillary , an open, contracted , or spikelike panicle, or composed of lax to spikelike racemes arranged along an elongate central axis, or digitate, paired , or occasionally solitary; axillary inflorescences often many, subtended by spatheoles (specialized bladeless leaf sheaths) and gathered into a leafy compound panicle; spikelets often aggregated into complex clusters in bamboos. Spikelets composed of distichous bracts arranged along a slender axis (rachilla) ; typically 2 lowest bracts (glumes ) empty, subtending 1 to many florets ; glumes often poorly differentiated from accompanying bracts in bamboos. Florets composed of 2 opposing bracts enclosing a single small flower, outer bract (lemma) clasping the more delicate, usually 2-keeled inner bract (palea) ; base of floret often with thickened prolongation articulated with rachilla (callus) ; lemma often with apical or dorsal bristle (awn ), glumes also sometimes awned . Flowers bisexual or unisexual ; lodicules (small scales representing perianth) 2, rarely 3 or absent, 3 to many in bamboos, hyaline or fleshy ; stamens 3 rarely 1, 2, 6, or more in some bamboos, hypogynous, filaments capillary , anthers versatile; ovary 1-celled, styles (1 or) 2(rarely 3), free or united at base, topped by feathery stigmas, exserted from sides or apex of floret. Fruit normally a dry indehiscent caryopsis with thin pericarp firmly adherent to seed, pericarp rarely free, fleshy in some bamboos; embryo small or large; hilum punctate to linear .

About 700 genera and 11,000 species: widely distributed in all regions of the world.[1]

Genus Deschampsia

Perennials , densely tufted . Leaf blades mainly basal, linear to setaceous , flat, folded or rolled; ligule membranous. Inflorescence usually an open panicle, infrequently contracted or spikelike; branches and pedicels usually filiform . Spikelets oblong to gaping , shining, laterally compressed , florets 2-3(-5), disarticulating below each floret; rachilla pilose , extended beyond uppermost floret; glumes lanceolate to oblong, subequal , ± equaling spikelet, membranous, shining, keeled , lower glume 1-veined, upper glume 1-3-veined; floret callus small, pubescent to conspicuously bearded ; lemmas lanceolate to oblong, hyaline to shiny cartilaginous , back rounded , finely 4-veined (5th midvein extended into awn ), glabrous , awned from near base or in lower half, apex membranous, broad, 4-toothed or denticulately truncate ; awn straight or weakly geniculate , usually not exserted from spikelet; palea hyaline, subequal to lemma. Ovary glabrous. Caryopsis with solid endosperm.

About 40 species: temperate and cold regions of the world; three species in China.[2]
