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]
