generally of G to 8 pairs of lieterogamous spikelets and a terminal 

 male ; rhachis-joints shorter than the ? spikelets, sparsely 

 puberulous with a short tuft of whitish hairs i>t the base, plane of 

 union clean, slightly oblique, round ; spikelets purplish, subfalcate, 

 narrowly elliptical, the sessile ( ^ ) slightly shorter than the 

 pedicelled (S); outer glume of sessile with nai-rowly keeled 

 margin scabridulous above, and flattened membranous encrved 

 back ; gl. II. 1-nerved, navicular, acute; gl. III. hyaline, lanceolate 

 blunt, enerved ; fertile glume hyaline, linear from a weak stipiti- 

 form base, 1-nerved, apex entire ; pale absent ; lodicules cuneate 

 with crenate apex, almost as long as the glabrous ovary ; styles 

 about }. length of stigmas; pedicel of c? spikelets shorter than 

 rliachis- joint, villous with short white hairs; gl. I. subacute with 

 narrowly carinate scabridulous margins, back 1-nerved; gl. II. 

 t)val, blunt, 3-nerved, margin inrolled, back round; gl. III. hyaline, 

 o-nerved, elliptical, blunt, margin ciliolate in the upper half ; 

 fertile glume oblong-elliptical 1-nerved. 



Plants 2 to 2-^ ft. high; radical leaves 10 in. long or less, 

 and 1?, line or less in width, plicate or subconvolute, the solitary 

 rauline leaf shorter often subtending a short liliform flowering 

 branch. Inflorescence about 10 in. long, lower branches 31 to 

 4i in., upper shorter and more crowded. Ultimate spathes I to 

 1 in. long, acute ; spikes generally H to ■} in. ; rhachis-joint 1 line 

 long, narrowly clavate ; sessile spikelet acute, 2 lines long ; gl. I. 

 1 J to scarcely 2 lines long, keels scabridulous in the upper two- 

 tliii-ds; gl. II. li line, upper half of keel scabridulous ; gl. III. 

 1 ] line, pinkish ; fertile glume 1 ] line. Pedicelled spikelet 21 to 

 2'-} lines long, including pedicel ; spikelet 2 lines ; outer glume with 

 keeled margin, scabridulous in the upper half to two-thirds ; gl. II. 

 1.^ to ly line; gl. III. 1^ line, pinkish; fertile glume 1^ line, 

 colourless ; anthers ^ line. 



Most nearly allied to the American A. spathijiorus Kunth, but 

 easily distinguished by its longer narrow i\aceme, and larger 

 spikelets. 



HriLLA. — A grass 2 to 2h ft., cajspitose, erect, rose-violet, with

 and spongy places near the streams in the Humpata district ; Dec.

PuNco AM)(tN(;(). — Growing sparsely (or perhaps already over) in 

 rather dry meadows near Bumba, not far from Condo ; a unique

10, A. huillensis Rendle sp. nov. 



Perennial, apparently cpespitose ; culms geniculate rising from a, 

 basal leafy tuft, lower internodes long, stout, subterete, like the 

 upper considerably exceeding the sheaths, nodes glabrous, long 

 slender flowering branches spring from the third and higher nodes ;
