Species

Angiosperms > Poales > Poaceae > Oxyrhachis

Characteristics

Densely tufted perennial, 200-600 mm high. Leaf blade 50-300 mm long, filiform; ligule a fringed membrane. Inflorescence a single, very slender, cylindrical, spike-like raceme; spikelets apparently borne singly, since pedicels fused to rachis and indistinguishable from internode; internodes semi-cylindrical, strongly oblique top and bottom; spikelets alternate and sunken on rachis. Sessile spikelet 3-6 mm long, dorsiventrally compressed, awnless; glumes ± equal, rounded on back, dissimilar; lower glume smooth. Florets 2; upper lemma less firm in texture than glumes; anther 2.0-2.5 mm long. Pedicelled spikelet and pedicel suppressed or fused and indistinguishable from internode. Flowering time June.
