Species

Angiosperms > Poales > Poaceae > Melinis

Characteristics

Tufted perennial (250-)400-1 200(-1 500) mm high, without knotty rootstock; basal leaf sheaths strongly overlapping. Leaf blade (30-)100-300(-440) x (1.3-)2.0-3.5(-4.5) mm, filiform, rolled. Inflorescence branches, branchlets and pedicels usually hairy and densely covered in long prickles, mostly stout, fairly rigid, only slightly wavy, often purple (in herbarium specimens mostly erect and closely adpressed to central axis). Spikelet (3.2-)3.6-5.0(-5.7) x 2 mm, narrowly ovate or narrowly oblong, densely villous with silky white, pink or purplish hairs extending up to 4 mm beyond apex, rarely glabrous or sparsely hairy; internode between glumes short 0.3(-0.6) mm long; lower glume (0.3)0.5-1.0(-1.9) mm long; upper glume back straight to slightly gibbous, 5(-7)-nerved, mucronate or awn 1-2(-3) mm long; lower lemma 5-nerved, palea keels ciliate; anthers 1.4ª2.2 mm long.

Perennial; up to 1.2 m high; tufted. Leaf blades (30-)100-300(-440) x (1.3-)2.0-3.5(-4.5) mm; rolled; basal leaf sheaths strongly overlapping. Flowers: panicle slightly contracted; branches; branchlets and pedicels often densely covered with hairs up to 4 mm long and prickles; pedicels white or purple; usually stout; straight or slightly wavy; spikelets (3.2-)3.6-5.0(-5.7) x 2 mm; internode between glumes 0.3(-0.6) mm long; lower glume 0.5 mm long; awns 1-2(-3) mm long.
Perennial, tufted, up to 1.2 m high. Leaf blades (30-) 100-300(-440) mm long, (l,3-)2.0-3.5(-4.5) mm wide. Basal leaf sheaths strongly overlapping; leaf blades rolled.
