Information
Loosely tufted annual; culms 10–90 cm. high, erect or ascending. Leaf-blades flat, up to 15 cm. long, 8 mm. wide, mostly glabrous and usually with a row of warty glands along the margin. Panicle ovate, 4–30 cm. long, fairly dense, contracted, stiffly branched, usually with glands on pedicels and branchlets. Spikelets 5–60-flowered, narrowly ovate to narrowly oblong, rarely linear, 3–20 mm. long, 2–4 mm. wide, pallid yellowish green to leaden grey, breaking up from the base, the rhachilla often breaking off above the glumes before all the lemmas have fallen; glumes subequal, ovate, boat-shaped, 1.5–2.2 mm. long, 1–3-nerved, often glandular on the keel, acute; lemmas broadly ovate to subrotund, (1.7–)2–2.8 mm. long, chartaceous, often glandular on the keel, the lateral nerves distinct, emarginate or obtuse (occasionally bluntly acute) when flattened, usually obtuse in side view; palea ± scabrid on the keels, persistent; anthers 3, 0.3 mm. long. Caryopsis typically subglobose, 0.5(–0.7) mm. long, dark reddish brown, occasionally oblong. Fig. 65.

Notes
CORRIGENDA (in Gramineae Part 3): p. 232. E. cilianensis (All.) F.T. Hubbard in Phillippine Journ. of Sci. Bot. 8: 159 (1913). The combination cannot be ascribed to Lutati, for he dismissed in favour of E. megastachya. Henrard (in Blumea 3: 420 (1940)) has pointed out that Allioni’s description of Poa cilianensis mentions 3—4 branches per node of the inflorescence, and has suggested that he was in fact describing P. trivialis L. However, the rest of the description, the figure (which shows only 1–2 branches per node), and the isotypes all contradict this view, and I have accepted Lutati’s conclusion that P. cilianensis is synonymous with the plant at one time known as Eragrostis major Host. See Sprague & Hubbard in K.B. 1933: 17 (1933) for full synonymy.  The species is best recognized by the warty glands on the leaf-margins, but unfortunately these are not always present. The rather stiff panicles of yellowish green or leaden grey spikelets are also characteristic. In Africa the species is rather variable, but there are no clear disjunctions upon which to base a subdivision.
