diameter, the lower clothed for about 4 the length with the leaf- 
sheath or its remains ; leaf-blades flat, 6 to 7 lines long by a 
little over 2 lines broad, more or less spreading. Panicle 4 to 
2 in. long, spikelets barely 1 line. Glume I. 3 line, gl. Il. $ line, 
gl. III. 2 line with a pale about ? its length, fertile gl. 3 line. 
Is near the tropical South American P. parvifolium Lam., but 
distinguished by its ovate leaves and smaller dense panicle. It 
recalls P. pusillum Hook. f. (Cameroons) in habit, but is a larger, 
stronger plant. P. pusillwm, moreover, has acute sparsely hairy 
spikelets.

Cespitose, apparently perennial; stems branching at the base 
only, erect, or geniculate at the lower nodes, slender, terete, 
glabrous; leaves subrigid, erect or ascending, narrow-linear, 
tapering gradually to an acute tip, glabrous except for a few 
scattered white hairs at the base of the blade, sometimes with 
involute margins and subulate-filiform ; ligule short, truncate, 
membranous; sheath appressed, generally shorter than the 
internode; panicle effuse, ovate or ovate-elliptical, branches 
capillary, flexuose ; spikelets long-stalked, small, roundish, the 
two barren outer glumes subequal, bearing soft white hairs, 
bluntly ovate, the lower 3-nerved, the upper 5-nerved ; gl. III. 
large, slightly exceeding gls. I. and II., blunt, orbicular, sub- 
coriaceous, 5-nerved, enclosing a large, subequal pale and a male 
flower, gl. IV. 2 the length of gl. IT., broadly ovate or suborbicular, 
enerved. 
An elegant plant 1 to 4 ft. high (some very slender starved 
specimens only 6 to 9 in.). Veins of leaf prominent on the back, 
sheaths striate with well-marked midrib, sometimes almost 
keeled; blade generally 3 to 6 in. long, by 1 line or less in 
width, sometimes longer in the subulate-filiform leaves. Panicle 
overtopping the leaves, 3 to 6 in. long, primary branches generally 
spreading at about 45°; spikelets 3 to 4 line long, greenish ; 
gl. IV. enclosing a similar but slightly smaller pale and 8 flower.
