panicles, and its pilose panicle and spikelets. The habit is some- 
what that of P. huwmile Nees, but the shoots are less spreading 
and the spikelets larger and more distant. 
Punco Anponco.—An annual grass, a foot high, erect, branched, 
with subpendulous hispidulous spikelets. Very rare by springs in 
high rocky places of the presidium near Quilombo ; end of April 1857. 
No. 2824. Also seen near Quilanga but not fully grown. A slender 
annual Panicum-like grass ; culms sparsely ceespitose, rather flaccid, 
very slender, erect or oblique; spikelets greenish. In wooded places 
by the banks of the river Luxillo between Pungo Andongo and 
Cambambe ; May 1857. No. 7421. 
29. P. pansum Rendle sp. nov. 
Annual, cespitose, shoots erect from an ascending base ; leaves 
ascending, hairy, linear-tapering, acute from a markedly striate 
sheath ; panicle very large, much-branched, branches long, 
ascending, spikelets solitary or in distant pairs, oval or oblong- 
oval, shortly acute, 1 line long; lowest barren glume ovate, acute, 
loosely embracing the base of the two higher and about 3 their 
length, incompletely 3-nerved, gls. TI. and III. ovate, subequal, 
and similar, 5- to 7-nerved, the latter with a short barren pale ; 
fertile gl. slightly shorter, suboval, coriaceous, with smooth 
rounded back and a similar equal pale. 
Strong-growing plants with a tufted growth, 3 ft. high; 
internodes in the stronger shoots 4 to 44 in. long, about 14 line 
in diameter ; nodes dark, glabrous. Sheaths 1} lines broad at the 
base of the shoots, + to + less than the smooth internodes; upper 
portion and margins hairy, sometimes scabrid. Blade 3 to 8 in. 
long by 22 to 3 lines greatest breadth, flat, lower face with 
prominent scabrid-hairy veins, margin and upper face also 
hairy; ligule short, breaking up into a ridge of short grey 
hairs. Panicle rather lax, 1 to 12 ft., branches solitary or in 
pairs, branchlets slender, flexuose, spikelets often long-stalked, of 
a shining gold colour. Barren glumes membranous, the lowest 
shortly acute, 3 to 1 line long, separated from the upper by a 
short internode ; gl. II. 1 to 14 line long, generally slightly longer 
than gl. III. (1 line), both broadly ovate, obtuse, or with margins 
incurved at the tip, forming a short point, pale of gl. III. about 
half its length. Fertile gl. + line long, ovately-oval or almost 
oval, indistinctly 5-nerved, yellow to a dirty brown in colour. 
The spikelet closely resembles that of P. atrosanguinewm, 
but the whole character of the plant and its large much-branched 
lax panicle at once distinguish it. The grain is also broader and 
lighter in colour.
