Names
POGONARTHRIA Stapf [family POACEAE], in Fl. Cap. 7: 316 (1898) & 589 (1900) & in Hook., Ic. Pl. 27, t. 2610 (1899)
Information
Tufted annuals or perennials. Leaf-blades linear, flat or loosely convolute; ligule short, densely ciliate. Inflorescence linear-oblong to pyramidal, composed of numerous short stiff slender racemes of crowded spikelets arranged along a central axis; racemes deciduous at maturity. Spikelets several-flowered, laterally compressed, biseriate, disarticulating between the florets or the lemmas falling leaving the persistent paleas on the rhachilla, shortly bearded with stiff hairs beneath the florets at the tip of each rhachilla-internode; glumes 1-nerved, keeled, unequal, shorter than the lemmas, membranous, acuminate; lemmas 3-nerved, with the lateral nerves 1/2–3/4 as long as the lemma, keeled, lanceolate, membranous, glabrous, acuminate or acuminate-aristate. Caryopsis elliptic-oblong to narrowly lanceolate, obtusely trigonous in cross-section.
Range
Species 4; tropical and South Africa, mainly on sandy soils.
