Information
perennial, frequently with extravaginal innovation shoots beside some intravaginal ones, or annual (or at least flowering the first year); culms fascicled, erect or shortly ascending, stout or rather so, 2–4 ft. long, simple and 4–7-noded below the spurious panicle; sheaths tight, quite glabrous, subherbaceous or the lowermost firmer and sometimes subpersistent, 2–3 in. long; upper shorter than the internodes; ligules very short, rounded; blades linear to linear-lanceolate from a broader rounded or subcordate base, tapering to a long setaceous point, 1/2–1 ft. by 3–6 lin. (in the South African specimens), flat, rather flaccid, dull-green or subglaucous, glabrous, smooth or the margins scabrid; panicles more or less compound, narrow, often interrupted, 4–6 in. long, rarely longer; racemes 4–9 lin. long, 2-nate, at length reflexed, or horizontally spreading on slender peduncles, which are 2–4 in. long, and subtended by lanceolate boat-shaped many-nerved scarious reddish spathes 1/2 to 1 in. long; joints and pedicels linear, slender or the lowest somewhat stout, 1–1 1/4 lin. long, densely hairy, mainly along the margins, tips minutely cupular, toothed; spikelets of the lowest pair of the sessile raceme alike, ♂, the sessile of all the other pairs hermaphrodite, the pedicelled ♂; hermaphrodite spikelets lanceolate, 2–2 1/4 lin. long, often variegated; lower glume subacute or obscurely 2-toothed, dorsally flattened with a narrow groove from the middle downward corresponding to a keel on the inner side, keels narrowly or obscurely winged and scabrid above, evanescent below; upper glume lanceolate, acute, 1-sub-3-nerved; valves hyaline, lower oblong, 1 3/4 lin. long, 2-nerved, ciliate; upper scarcely shorter, very narrow, linear, deeply bifid, lobes very fine, awn 5–7 lin. long, slender, bent just below the middle, glabrous below the bend; pale 0; anthers 1 lin. long; pedicelled spikelets oblong, subacute, 2 lin. long; lower glume 9–11-nerved, upper 3-nerved; lower valve oblong, almost equalling the glumes, 2-nerved, upper and pale 0; anthers 1 1/2 lin. long. null

Notes
The specimens from Bloemfontein and Johannesburg have very narrow leaves, and meagre inflorescences, like those of var. cæsius (Hackel); but I consider them only as slight variations due to a particularly dry habitat. Hackel indicates also the typical form, which is a more robust plant having longer and much broader blades and larger more compound panicles, from “Caffraria.” I have not seen it from extra-tropical South Africa, unless a specimen, collected by Buchanan, 134 in part, on the Natal Coast is referable to it. A specimen, collected by Fleck at Rehoboth, Great Namaqualand is referred by Hackel (in Bull. Herb. Boiss. iv. App. iii. 12) to A. “Schœnanthus, L. sens. ampl.” Thunberg enumerates A. Schœnanthus in Prod. Pl. Cap. 20 and in Fl. Cap. ed. i. 407 and ed. Schult. 108. Nees refers it to his A. Iwarancusa which is A. Nardus var. marginatus. There is, however, no such plant in Thunberg's Cape collection so far as I have seen it; but the localities given by Thunberg in his Flora Capensis, namely, Lange Kloof and Kromme River, render it very probable that Nees was right.
