distinguished by its less diffuse panicle, with short branchlets 
and short-stalked spikelets, also by its glabrous ellipsoidal grain. 
Pungo ANDONGO ?—No. 28626 (no information). 
17. E. agrostoidea Rendle sp. nov. 
Annual, culms erect from an ascending base or spreading 
and often branching profusely at the strong geniculate nodes, 
internodes terete, polished, with a glandular ring just below 
the brown internode; leaf-sheaths terete, or subcompressed and 
often subcarinate, except the lowermost shorter than the inter- 
nodes, more or less glandular-punctate, conspicuously hairy at 
the mouth; ligule a short dense row of hairs; blades rigidulous, 
spreading, linear-tapering, acute, more or less convolute, scabridu- 
lous, sometimes sparsely hairy below, base of midrib with a row 
of glands; panicle oblong or ellipsoidal to pyramidal, glabrous, 
branches spreading or ascending, whorled and scattered, slender, 
subrigidulous, bearing branchlets or spikelets almost from the 
base; spikelets a dull olive-green, generally shortly stalked, soft, 
subcompressed, compact, linear, generally 6- to 8-flowered ; barren 
glumes thinly membranous, subequal, inconspicuously 1-nerved, 
lanceolate to ovate, generally acute, reaching about to the tip of 
the two lowest fertile glumes, the midrib dorsally subscabridulous 
in the upper portion, the upper broader than the lower, and often 
less acute; fertile glumes glabrous, with rounded back, broadly 
elliptical to orbicular-ovate, apex rounded or blunt, 3-nerved, 
the outer nerves submarginal and curved, falling short of 
the apex; pale persisting after fall of the glume, weakly 
bicarinate, keels scarcely scabridulous in the upper part; 
grain shortly ellipsoidal, pale transparent brown with a darker 
hilum. 
Plants 8 to 18 in. high, of slender graceful habit, culms more 
or less rigid with 3 to 4 internodes. Leaf-sheaths generally 
between 1 and 3 in. long, ligule } line long, leaves 1 to 4 in. 
Panicle from less than 3 to 6 in. long, generally between 1 and 2 
in. broad, sometimes broader at the base; spikelets about 2 lines 
long or less; barren glumes 2 to nearly 1 line long, fertile 
glumes $ to 3 line long, pale slightly shorter ; anthers brown, 
4 line long ; grain + line. 
Recalls #, pilosa Beauv., but has a stiffer habit, larger sub- 
equal barren glumes, etc. Apparently nearest EZ. porosa Nees, 
but distinguished by its dark-coloured, more compact spikelets, 
and subequal barren glumes. 
AmBaca.—A slender grass with the habit of Agrostis, 1 ft. or 13 ft. 
high ; culms branched. Fields near Ambaca, No. 2746; mandioca 
plantations near Ngombe (Residencia do Distos) but better specimens 
vainly sought for, No. 7319 ; Oct. 1856. 
Loanpa.—An annual ; somewhat plentiful round ponds and in their 
clayey bottom when dried up not far from Forte de Conceigad, 
No. 7295 ; and in abandoned fields at Represa do M. Pereira near the 
river, No. 7295) ; July 1894.
