Information
A compact caespitose often stoloniferous perennial, usually densely glandular-pubescent all over. Culms 5-15 (rarely to 40) cm. tall, 2-5-noded, geniculately ascending, sometimes decumbent, often with a bulbous thickening at the base, simple or branched, rather slender, asperulous. Leaves mostly confined to the base, forming dense tufts; sheaths tight at first later somewhat loose, finely to coarsely striate, the oldest long-persistent and splitting into fibres which form dense cushions at the base of the culm. Leaf-laminae 2.5-7.5(12) x 0.3-0.5 cm., filiform, almost always convolute, tapering to a very fine point, flexible, asperulous. Panicle 1.5-5(7.5) cm. long, spike-like, narrowly cylindrical or rarely ovate-oblong in outline, rather dense, light to dark grey. Spikelets 3-5.5 mm. long, 3-flowered (see note below), crowded. Glumes subequal, oblong, scantily pilose, with the apex obtuse to slightly emarginate, light to dark grey; the inferior 2.3-5 mm. long, 3-7-nerved; the superior 2.8-5.5 mm. long, 3-5-nerved. Fertile lemma (the inferior) 1.5-2 mm. long (excluding the awns), dorsally shortly villous; awns 2-4 mm. long, shortly plumose to or beyond the middle. Anthers 0.3-0.5 (rarely 0.7) mm. long. Caryopsis c. 1 mm. long.
Habitat
Growing in open grassland, in limestone pans, on grassy hillsides and stony outcrops, also on thin soil overlapping basalt rocks, often in overgrazed areas
Range
North Africa from the Cape Verde Islands to Egypt, through Arabia to India and China, in tropical Africa from Chad and Somalia southwards to the Cape Province
Distribution
Botswana SE Khomodimo Pan, 206 miles NW. of Molepolole, 18.vi.1955, Story 4926 (K; PRE).Botswana SW 9?6 km. SW. of Takatshwane on road to Lehututu, 21.ii.1960, de Winter 7420 (K; PRE; SRGH).Zimbabwe S Beitbridge, Shashi-Limpopo confluence, 22.iii.1959, Drummond 5949 (BM; SRGH).Botswana N NE. corner of Makarikari Pan, 16.i.1959, West 3863 (BM; SRGH).
Distribution (external)
south-western Africa
southern Angola
Notes
This sp. often produces cleistogamous spikelets, which are usually enclosed within the bulb-like enlarged basal leaf-sheaths. The caryopsis of these spikelets is conspicuously larger than that of normal spikelets, and remain enclosed within the sheaths where it finally germinates. Occasionally small panicles, which produce normal spikelets, are also produced within basal or nodal leaf-sheaths.
