barren glume 1} line, inner 14 line not including the hairs which 
exceed it; hairs reddish or whitish, borne on the back of the 
margin in the upper half, and in two tufts on either side of the 
base ; fertile glume 1} line, inconspicuously 3-nerved; pale flat, 
punctulate dorsally like the glume. Lodicules cuneate-quadrate. 
Recalls the South African forms of Panicum commutatum Nees, 
but is distinguished at once by its less regular binate spikes, with 
broader strongly convex long-silky-haired spikelets.

9. D. angolensis Rendle sp. nov.

leaves rather broadly linear, tapering to the base and acute apex, 
ligule membranous truncate, sheaths longer than the internodes ; 
spikes (8) subcorymbosely fastigiate, rhachis narrow, trigonous ; 
spikelets crowded, in groups of 4, plano-convex, softly pubescent,

glabrous ; leaf-sheaths loose, glabrous or sparsely hairy in their 
upper part, where they may also be subcarinate ; blades glabrous, 
spreading, margin thickened and minutely crispulate, midrib sub- 
prominent below, 5 to 7 in. in length by 4 lines in breadth. 
Spikelets long- and short-stalked, often viviparous. Subsidiary
