30. P. coloratum LL. Mant. p. 30 (1767). 
Var. strictum Rendle var. nov. nL 
Differs from the species in its stricter panicle and more rigid 
spikelets, with a very blunt often truncate outermost barren glume. 
Huitta.—Rather damp clayey wooded meadows near Catumba ; 
end of March 1860. No. 2688. 
Var. cuanzense Rendle var. nov. 
A laxer plant with a larger panicle and slightly smaller less 
rigid spikelets than in the species. The structure of the spikelets 
resembles that of the latter too closely to allow of its specific 
separation. I have therefore adopted Welwitsch’s ms. name, 
reducing it to varietal rank. 
LoanpDA ?—No. 7355 (no information). 
Punco AnDonNGo.—Annual; culms sparsely and laxly czspitose, 
erect, panicle effuse, much branched. In rather damp sandy places at 
the great cataract of the river Cuanza near Condo; March 1857. 
No. 2833. Cou. Carp, 1083. 
31. P. subrepandum Rendle sp. nov. 
Perennial, shoots slender, erect, unbranched, or rarely with a 
short leafy branch at the base, leaves suberect, narrow-linear, 
acute ; panicle effuse, lax-flowered with rhomboidal or ovate 
outline, spikelets ovate, 12 to 14 line long; gl. I. reaching to 
about 2 the length of the spikelet, broadly oval, blunt, 3-nerved, 
gls. IT. and III. equal, 5-nerved, the former with a broadly- 
rounded back, and suborbicular when flattened, the latter forming 
a hood with broad translucent margins and sheltering a pale and 
a & flower; fertile gl. whitish, subcoriaceous, convex, covered 
with large warts, as is also the back of the pale. 
Shoots 18 to 22 in. long, glabrous, crowded on a thin knotted 
rhizome with slender wiry roots. Internodes 1 to 3 in. long, 
slender, terete, striate; nodes smooth, glabrous. Sheaths narrow, 
striate with minutely ciliate margins, completely enveloping the 
lower internodes, about 2 the length of the one below the 
inflorescence ; ligule short, truncate, brown, membranous, shortly 
fimbriate ; blade 2} to 4 in. long, by 1+ line or less in width, 
midrib conspicuous below. Panicle 3} to 4 in. long on a 
stalk 8 to 12 in.; branches alternate, spreading at an angle of 
about 45° and bearing filiform subspreading branchlets, which 
again branch and bear the subdistant long and shortly-stalked 
spikelets. Glume I. barely 1 line long, broadly oval to sub- 
orbicular, edges broad, translucent; gl. IT. 1} line long, with 
rounded incurving edges, giving a broadly oval outline and a 
bluntly apiculate apex; gl. III. broader, pale oval when in 
position with broad edges sharply infolded at the strong con- 
verging nerves. Fertile gl. enveloped vy the *econd barren 
glume, $ to { line long, suborbicular when flattened, 5-nerved ; 
pale oval in outline except for the broadly overlapping sides. 
Near P. natalense Hochst., which is distinguished by its long 
vigid convolute leaves, more strongly nerved glumes, and the 
absence of the large warts on the fertile glume and pale.
