Characteristics

Loosely or densely tufted perennial, 0.3-1.0 m high; sometimes shortly rhizomatous; often reddish or purple-tinged when flowering. Leaf blade 50-180 x 2-6 mm, dried leaves curled like a corkscrew; ligule an unfringed membrane. Inflorescence of solitary racemes, enclosed in reddish brown, boat-shaped, acuminate spatheoles, loosely gathered into an open, false leafy panicle; spikelets paired: one sessile, the other pedicelled. Sessile spikelet 3.5-4.0 mm long, dorsiventrally compressed; glumes ± equal, dissimilar, awned. Florets 2; lower floret sterile, reduced to a hyaline, hairy lemma, awnless; upper floret bisexual; lemma less firm than glumes, glabrous, deeply 2-lobed, awned from between lobes; awn delicate, 6-20 mm long, much longer than body of lemma, geniculate, twisted, glabrous; anther 1.5-2.0 mm long. Pedicelled spikelet 4.0-5.0 mm long, broadly lanceolate, resembling sessile spikelet but slightly longer and wider, male, awnless; anther 1.5-2.5 mm long. Flowering time Jan.-June.
More
Perennial of variable habit; at one extreme the culms up to 130 cm. high, leafy, erect but weak and easily lodged by rain, sometimes straggling; at the other extreme the culms as little as 30 cm. high, wiry, and arising from a basal tussock of leaves mixed with the fibrous remains of old sheaths.. Leaf-blades 5–25 cm. long, 2–5 mm. wide, glabrous or hairy.. False panicle linear, open; spatheoles narrowly lanceolate, 2–4 cm. long, reddish brown.. Sessile spikelet elliptic, 3–4 mm. long; callus longer than wide, hairy on sides and base; lower glume softly pilose to villous; upper glume with an awn 2–6 mm. long; upper lemma with an awn 6–20 mm. long.. Pedicelled spikelet similar to sessile, but awnless and with a callus 0.5–1 mm. long.. Fig. 190.
Loosely or densely tufted, graceful perennial 300-1000 mm high; sometimes shortly rhizomatous; plant turns reddish or purple-tinged when flowering. Leaf blade 50-180 x 2-6 mm, dried leaves curled like a cork-screw. Inflorescence of solitary racemes partly enclosed in reddish-brown, boat-shaped spatheoles; spatheoles 16-40 mm long. Sessile spikelet 3-4 mm long; upper glume awn 3-6 mm long; upper lemma awn 6-15 mm long; anthers 1.5-2.0 mm long. Pedicelled spikelet 4-5 mm long, anthers 1.5-2.5 mm long.
Perennial; up to 1 m high; sometimes shortly rhizomatous; loosely or densely tufted. Leaf blades 50-180 x 2-6 mm. Flowers: in a complex; false panicle; racemes solitary; partly enclosed in reddish brown; boat-shaped spatheole; spikelets (sessile and pedicellate) 3.54.0 mm long; plant reddish or purple-tinged when flowering.
Perennial of variable habit ranging from plants up to 130 cm high with weak culms easily lodged by rain and sometimes straggling, to plants scarcely exceeding 30 cm with wiry culms arising from a basal tussock of leaves mixed with the fibrous remains of old sheaths; leaf laminas 5–25 cm × 2–5 mm, glabrous or pilose.
Graceful perennial, sometimes shortly rhizomatous and tufted (loosely or densely), up to 1 m high, reddish or purple-tinged when flowering. Leaf blades 50-180 mm long, 2-6 mm wide. Spikelets (sessile and pedicellate) 3.5-4.0 mm long. Racemes solitary, partly enclosed in reddish brown boat-shaped spatheole.
Sessile spikelet 3–4 mm long, elliptic; callus longer than wide, pilose on both sides and at the base; inferior glume softly pilose to villous; superior glume with an awn 2–6 mm long; superior lemma with an awn 6–20 mm long.
A tufted perennial somewhat fibrous at the base; densely caespitose in southern Africa, but in our region usually 90–120 cm. high
Pedicelled spikelet similar to the sessile spikelet, but awnless and with a callus 0.5–1 mm long.
False panicle linear, open; spatheoles 2–4 cm long, narrowly lanceolate, reddish-brown.
Erect leafy culms, these weak and often lodged by heavy rain
