Panicum XXVIII, GRAMINES, 169 
at the lower nodes and densely leafy below ; leaves short, linear- 
lanceolate, acute, margins thickened, often minutely aculeate ; 
spikes 1 or 2, short, consisting of a row of oval sessile spikelets 
alternating on the lower surface of the somewhat broadened 
rhachis ; glume I. oblique, with numerous parallel nerves, loosely 
wrapping the base and as long as the spikelets ; gls. IT. and III. 
similar, slightly shorter than gl. I., veins (7 or 5) with con- 
spicuous cross unions, the third subtends a large pale with a 
3 flower; fertile gl. equal to II. and IIT., concave, oval, finely 
transversely rugulose. 
Shoots to 13 ft. long; nodes glabrous; lower internodes 
short slender (1 in. or less) completely covered by the loose 
subcompressed sheaths which are striate and glabrous with shortly 
hairy edges and mouth. Ligule very short, truncate, membranous ; 
leaf-blades ascending or spreading, glabrous beneath, sparsely 
hairy above, 13 to 22 in. long, 3 to 4 lines broad, flattened or with 
incurving edges. Spikes single, or a secund pair at the end of 
the long slender axis, 2 to 1 in. long. Spikelets 8 to 10 in a 
dense single row ; the very short pedicel bears a few white hairs. 
Glume I. large, membranous, ovate to oval, with a rounded apex 
and numerous (17) parallel nerves, 14 line long; gl. II. mem- 
branous, broadly oval, rounded, nerves 7, converging above, 14 
line long; gl. III. 5-nerved, with a broad pale with well-marked 
nerves and strongly incurved edges, anthers orange-coloured ; 
fertile gl. with a closely fitting pale and @ flower; lodicules 
large (2 line long), subquadrate. 
Near P. falciferwm Trin., but distinguished by its broad spread- 
ing leaf-blades, its glabrous spikelets arranged in a single row 
with the large loose many-nerved outer barren glume.

No, 2726. Common in sandy low-lying wooded meadows between 
Condo and Quisonde ; March 1857. No. 2829. 
A specimen collected in Gambia by Mungo Park belongs to the 
same species. It has longer leaves (24 to 43 in.) and spikes (to 14 in.) 
than Welwitsch’s plants. 
6. P. humidicolum Rendle sp. nov. 
Stem stout, creeping, branching at its terminal node and 
emitting a tall ascending thin erect shoot ; leaves stiff, broadly 
linear-lanceolate, subacute ; spikes 4 to 5, secund; spikelets 
large (23 lines) oval, in a dense single row on the lower 
face of the scarcely broadened rhachis; glume I. nearly as long 
as the spikelet, blunt with numerous parallel nerves; gls. II. 
and JII. equal, hairy on the back, 7-nerved, with con- 
spicuous cross-unions, blunt or apiculate, the third subtending 
a pale with a d flower; fertile gl. oval, minutely apiculate and 
finely transversely rugulose. 
Creeping stem 1 ft. long in the single specimen, internodes 
1 to 3 in. long by 2 lines in thickness, leaves as in the erect shoot. 
Erect shoot, with a geniculate ascending base, 4 ft. long ; lower 
internodes 3 in. long, upper much longer, and with a circlet of
