Morphology Reproductive morphology Inflorescences
Inflorescence a lax anthela of 1 sessile spikelet and 1–numerous stalked spikelets or new groups of sessile and stalked spikelets, more rarely spikelets congested, or inflorescence a terminal spikelet only; involucral bracts usually leafy and spreading, shorter or longer than the inflorescence
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets ovate to elongate, with numerous bisexual flowers subtended by spirally arranged glumes
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes ovate to lanceolate or almost orbicular, glabrous or short-hairy, sometimes with longer hairs on margin; midrib ending below apex or excurrent in a short or long mucro or awn
Morphology Reproductive morphology Flowers Perianth
Perianth absent
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 1–3
Morphology Reproductive morphology Flowers Gynoecium Style
Style often strongly flattened and fimbriate, with 2 or 3 stigmas; base of style widened but falling with the rest of the style, very rarely with slender processes descending from the style-base over the nutlet
Morphology Reproductive morphology Fruits
Nutlet orbicular or obovate to almost cylindrical, triangular or biconvex, smooth, tuberculate or reticulate with hexagonal or linear surface cells that are never longer than wide when seen from base towards apex.
