panicles, and its pilose panicle and spikelets. The habit is some- 

 what that of P. humile Nees, but the shoots ai-e less spreading 

 and the spikelets larger and more distant. 



PuNfio Andon(;o. — An annual gi'ass, a foot high, erect, branched, 

 with subpendulous hispidulous spikelets. Very rare by springs in 

 high rocky places of the praosidium near Quilombo ; end of April 1857. 

 No. 2824. Also seen near Quilanga but not fully grown. A slender 

 annual Pa)iivuin-\\k.e grass ; culms sparsely caespitose, rather flaccid, 

 very slender, erect or oblique ; spikelets greenish. In wooded placef^ 

 by the banks of the river Lu.xillo between Pungo Andongo and 

 Cauibambe ; May 1857. Xo. 7421. 



29. P. pansum Rendle sp. nov. 



Annual, caespitose, 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 f their 

 length, incompletely 3-nerved, gl.s. TI. and III. ovate, subequaJ, 

 and similar, 5- to 7-nerved, the latter with a short Imrren pale ; 

 fertile gl. slightly shorter, suboval, coriaceous, witli smooth 

 rounded back and a similar equal pale. 



Strong-growing phxnts with a tufted growth, 3 ft. high ; 

 interned es in the stronger shoots 4 to 4i in. long, about 1^ line 

 in diameter; nodes dark, glabrous. Sheaths 1^ lines broad at the 

 base of the shoots, i to -]- less than the smootli internodes ; upper 

 portion and margins hairy, sometimes scabrid. Blade 3 to 8 in. 

 long by 21- to 3 lines greatest breadth, flat, lower face with 

 prominent scabrid-hairy veins, margin and upper face also 

 iaairy ; ligule short, breaking up into a ridge of short grey 

 hairs. Panicle rather lax, 1 to 1^ ft., branches solitary or in 

 pairs, branchlets slender, flexuose, sjaikelets often long-stalked, o^' 

 a shining gold colour. Barren glumes membranous, the lowest 

 shortly acute, ^ to 1 line long, separated from the iipper by a 

 short internode : gl. II. 1 to 1| line long, generally slightly longer 

 than gl. III. (1 line), both liroadly ovate, obtuse, or with margins 

 incurved at the ti}), forming a short point, pale of gl. III. about 

 half its length. Fertile gl. 4 line long, ovately-oval or almost 

 oval, indistinctly 5-nerved, yellow to a dirty br-own in colour. 



The spikelet closely resembles that of P. atrosangui7ieum, 

 but the whole charactei' of the plant and its large much-branched 

 lax panicle at once distinguish it. The grain is also broader and 

 lighter in colour.
