Information
Perennial, loosely to densely tufted. Culms erect or more often geniculately ascending, up to 3 1/2 ft. high, slender to very slender, wiry, terete, simple or branched, 2–5-noded, darkened around the nodes, glabrous and smooth, rarely softly hairy. Leaf-sheaths shorter than the internodes, with or without a ring of hairs on each side of the nodes, the lower (rarely the upper) loosely beset with tubercle-based hairs or glabrous like the upper; ligule a ciliate rim; blade linear, tapering to a fine point, 1–6 (rarely more) in. long, up to 2 1/2 lin. wide, flat, firm, at length spreading or reflexed, loosely to sparsely hirsute with tubercle-based hairs, or glabrescent. Panicle loose, 1–9 in. long, up to 3 in. wide; rhachis smooth, darkened at the lower nodes; branches fascicled or paired, or the lower semi-verticillate, up to 3 1/2 in. long, loosely divided or simple, filiform, scaberulous; pedicels 1–5 lin. long. Spikelets lanceolate to lanceolate-oblong, 3 1/4–5 (rarely more) lin. long, brown or greyish-brown. Glumes chartaceous, 3-nerved, setulose (especially on the nerves) with rigid white hairs from minute dark brown tubercles, rarely glabrescent; lower narrowly ovate to ovate-oblong, obtuse or truncate, 1 1/2–2 1/2 lin. long; upper linear-lanceolate, truncate or obtuse, as long as the spikelet, glabrous in the upper third. Lower floret ♂: valve oblong-lanceolate, acute or obtuse, 3–4 lin. long, 3-nerved, setulose in the upper two-thirds (especially on the nerves), or glabrescent; valvule linear, obtuse, 2 1/4–3 lin. long. Upper floret linear: callus minutely 2-toothed, 1/4– 1/3 lin. long, bearded; valve 1 3/4–2 1/4 lin. long, very minutely and obtusely 2-lobed, coriaceous, 7-nerved, finely pubescent; awn 3/4–1 1/4 (rarely to 1 1/2) lin. long, very slender; column scaberulous, 3–5 (rarely to 6 1/2 lin.) long; valvule linear, 2 lin. long. Anthers 2, 1–1 1/2 lin. long.

Notes
Loudetia kagerensis is fairly uniform in structure and habit throughout Uganda, Kenya Colony, and Tanganyika Territory. The spikelets are typically setulose, but in the type of Trichopteryx spirathera, K. Schum., they are glabrescent. T. kapiriensis, De Wild. (Belgian Congo: Homblé, 1055) differs from the remainder of the specimens cited above in having hairy culms, pale nodes, a prominently nerved upper surface to the leaf-blades, and a relatively shorter lower glume (about three-eighths the length of the spikelet).
