Physical 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 Eulaliopsis:

Perennial. Leaf blades narrow; ligule a long-ciliate rim. Inflorescences terminal and axillary from upper leaf sheaths, composed of a few subdigitate racemes; racemes conspicuously hairy, fragile, sessile and pedicelled spikelets of a pair similar, both fertile; rachis internodes and pedicels flat, ciliate. Spikelets elliptic-oblong, lightly laterally compressed below middle, flat above; callus densely bearded; glumes villous below middle; lower glume papery, convex, 5-9-veined, veins prominent, apex shortly 2-3-toothed; upper glume 3-9-veined, apex acute or 2-toothed, with or without an awn-point; lower floret male or sterile, lemma and palea well developed, hyaline; upper lemma lanceolate-oblong, hyaline, entire or minutely 2-toothed, awned; awn weakly geniculate; upper palea broadly ovate, glabrous or apex long ciliate. Stamens 3.

Two species: Afghanistan and India to China and Philippines; one species in China.^[2]
