Information
A densely tufted perennial; innovations intravaginal. Culms erect, 1 1/2–4 ft. high, slender to moderately stout, terete or slightly compressed, simple, 2–3-noded, loosely to densely pilose or villous below the inflorescence and sometimes sparsely hairy below the nodes, otherwise glabrous and smooth. Leaf-sheaths usually overlapping, striate, loosely hairy upwards mostly from minute tubercles, densely ciliate on the margins, or glabrescent except for the densely woolly mouth, or quite glabrous; ligule reduced to a densely ciliate rim; blade linear from a narrow base, tapering to a hard obtuse or acute tip, up to 14 in. long, involute or convolute, up to 2 lin. wide when opened out, rigid, sparsely hairy from minute tubercles or glabrous, prominently nerved, smooth. False spike cylindric, very dense, erect, straight or flexuous, 1 3/4–3 1/2 in. long, 3 1/2–4 lin. wide (exclusive of the bristles), usually pale yellow or pale green; rhachis minutely hispidulous or scaberulous, densely beset with the thickened minute hispidulous-tipped stumps of the deciduous involucres; involucres sessile, shortly bearded at the base, at length horizontally spreading; bristles 10–18 to each involucre, very slender, scaberulous, of unequal length, free to the base, glabrous or the inner more or less loosely ciliate around the spikelet with fine white hairs, pallid, one or two stouter than the rest and up to 6 lin. long, the remainder varying in length and up to 4 1/2 lin. long. Spikelets solitary, sessile within the involucre, lanceolate or lanceolate-oblong, acute or acuminate and mucronate, 1 3/4–2 1/2 lin. long, glabrous. Lower glume lanceolate to broadly elliptic, more or less obtuse or acute, 1/4– 3/4 lin. long, hyaline, nerveless or 1-nerved; upper broadly ovate to elliptic, acute or abruptly acuminate and mucronulate, 3/4–1 1/2 (rarely 2) lin. long, thinly membranous, 1–3-nerved. Lower floret barren and reduced to the valve: valve when flattened lanceolate or oblong-lanceolate, finely acute or acuminate, as long as the spikelet, membranous, 3–5-nerved, minutely scaberulous towards the apex; valvule suppressed. Upper floret hermaphrodite, lanceolate, finely acute and mucronate: valve when flattened elliptic or ovate-elliptic, acute or acuminate, mucronate with the mucro scaberulous, as long as the spikelet or usually slightly shorter, firmly membranous, 5-nerved; valvule lanceolate, acute, slightly shorter than the valve. Lodicules 1/6 lin. long. Anthers dark, 1–1 1/4 lin. long, with glabrous tips. Styles free to the base; stigmas dark purple.

Notes
Vern. Name:— Gutu (Kikuyu). Very closely allied to the South African Pennisetum sphacelatum, Durand and Schinz, which has, however, finer leaves with a different structure. The majority of the Abyssinian specimens have glabrous bristles and represent typical Pennisetum Schimperi; those from Kenya Colony have the inner bristles more or less loosely ciliate below the middle and represent the form described as P. Merkeri by Leeke. Adamson's plant from Mt. Mlanje, Nyasaland, has purple panicles and glabrous bristles; it is doubtfully referred to this species.
