168 XXVIII. GRAMINES. [Panicum 
membranous, pilose; blade stiff, glabrous, 1} to 32 in. long by 
2 to 4 lines broad. Spikes generally 8, near the end of the long 
axis, separated by internodes about equal to their own length, 
decreasing in size from below upwards, 2- to 8-flowered, the upper- 
most reduced to a single spikelet, rhachis sparsely pilose. Glume I. 
triangular-ovate, membranous, 3-nerved, ? line long; gl. IL 
thicker, very broadly oval, very concave and blunt, inconspicuously 
5-nerved, 1 line long; gl. III. concave, with edges strongly 
incurved above, and apiculate, 5-nerved, 14 line long, enclosing a 
membranous obovate pale with edges sharply inflexed at the strongly - 
marked nerves; anthers dark-coloured; fertile gl. coriaceous, 
minutely scabrid, blunt, very inconspicuously 3-nerved, 1} line 
long, the incurved edges enclosing the well-fitting pale. 
The form of the inflorescence and the shape of the spikelet 
recall P. brizoides Lam., but the rhachis is slender, not broad as in 
that species, while the habit and the stiff lanceolate leaves with 
their minutely serrulate margin are very characteristic and distinct.

A larger coarser plant than the Huilla one, and also characterised by 
the broad rhachis fringed with ferruginous hairs twice as long as'the 
spikelets. Specimens collected in Gambia by Mungo Park resemble 
this form.

‘Smaller slenderer plants than those from Pungo Andongo, the 
narrower rhachis bearing only a few almost colourless hairs, resembling 
therein Trinius’ figure and description. 
There is some discrepancy in the size and neuration of the 
outermost glume in the specimens which I have examined and 
Trinius’ figure. In plants from Cape Coast, Accra, Gambia, and 
Angola it is invariably truncate and generally 5-nerved. It 
varies in length from 3 to # the length of the third glume.
