30. P. coloratum L. Mant. p. oO (1767). 

 Var. strictum Renclle var. nov. 



Differs from the species in its stricter panicle and more rigid 

 spikelets, with a very blunt often truncate outermost barren glume. 



Huii.LA. — Rather damp clayey wooded meadows near Catumba : 

 end of March 1860. No. 2688. 



Vai-. cuanzense Rendle var. nov. 



A laxer plant with a larger panicle and slightly smaller less 

 rigid spikelets than in the species. The structure of the spikelets 

 i-esembles that of the latter too closely to allow of its specific 

 separation. I have therefore adopted Welwitsch's ms. name, 

 reducing it to varietal rank. 



LoAND.v ? — No. 7355 (no information). 



PiTN(K) ANnoxGo.— Annual ; culms sparsely and laxly casspitose, 

 erect, panicle effuse, much branched. In rather damp sandy places at 

 the great cataract of the river Cuanza near Condo ; March 1857. 

 No. 2833. Com.. Carp. 1083. 



31. P. subrepandum Rendle sp. nov. 



Perennial, shoots slender, erect, unbranched, or rarely with a 

 short leafy branch at the base, leaves suberect, narrow-linear, 

 acute ; panicle effuse, lax-flowei-ed Avith rhomboidal or ovate 

 outline, spikelets ovate, 1^ to 11 line long; gl. I. reaching to 

 about H the length of the spikelet, broadly oval, blunt, 3-nerved, 

 gls. ii. and III. equal, 5-nerved, the former with a broadly- 

 rounded back, and suborbiculav when flattened, the latter foi-ming 

 a hood with broad translucent margins and sheltering a pale and 

 a (^ flower ; fertile gl. whitish, subcoriaceous, convex, covered 

 with large warts, as is also the back of the pale. 



>Shoots 18 to 22 in. long, glabrous, crowded on a thin knotted 

 rliizome with slender wiry roots. Internodes 1 to 3 in. long, 

 slendei', terete, striate ; nodes smooth, glabrous. Sheaths narro-vv, 

 striate with minutely ciliate margins, completely enveloping the 

 lower intei-nodes, about ?. the length of the one below the 

 inflorescence ; ligule short, truncate, brown, membranous, shortly 

 fimbriate ; blade 21 to 4 in. long, by 1} line or less in width, 

 midrib conspicuous below. Panicle 3?^ to 4 in. long on a 

 stalk 8 to 12 in. ; branches alternate, spreading at an angle of 

 about 45° and bearing filiform subspreading branchlets, which 

 again branch and bear the subdistant long and shortly-stalked 

 spikelets. Glume I. barely 1 line long, broadly oval to sub- 

 orbicular, edges broad, translucent; gl. II. 1^ line long, witli 

 lounded incurving edges, giving a broadly oval outline and a 

 bluntly apiculate apex; gh III. broade)', pale oval when in 

 position with broad edges sharply infolded at the strong con- 

 verging nerves. Fertile gl. enveloped oy the second barren 

 glume, i to ^ line long, suborbiculai- when flattened, 5-nerved ; 

 2)ale oval in outline except foi- the broadly overlapping .sides. 



Near P. imtalense llochst., which is distinguished by its long 

 ligid convolute leaves, more strongly nerved glumes, and the 

 ab.sence of the large warts on the fei-tile glume and pale.
