 aphylla amplexa, culmo breviora, stricta, e semitereti compressa, apicera versus potius trigona, apice 

 rigido fusco, margine tevia. Vagina striate, spice obtuse carinate margine fusco-membranaceo in ligulam

 semiteretia, apice tereti-trigona; vagina ut in illis. Spica 2-6-pollicaris, decomposita, e spicis partialibus 

 6-10 approximatis, alternis, tri-unipollicaribus, summis semipollicaribus. Rachis depresso-semi-teres, tevis, 

 altero latere canaliculate. Bractea sub singula spica partiali ovalis, scariosa, fusca, basi vaginans, apice 

 contracto in mucronem rectum linearem planum obtusum procurrens, spica partiali brevior, nervoso- 

 -striata pruinosa. Spica partiales 6-5, alternae, approximate, ovate, 1-1^ poll, longae, bracteate. Spi- 

 cula in ramulo suo subimbricate, geminae vel solitariae, bracteola communi siinili aristulata longitudine 

 spicularum stipatae, lanceolate, l£-2 lin. longae, compressaa, squamis 5-6 aequalibus trifariam imbricatis char-

 trigonum, in styli basin crassiusculam connivens. Spica fructifera major, subnutans. Caryopsis nucamen- 

 tacea, ovalis, subtrigona, mucronulata, fusca, albo-irrorata, lsevis, basi perigynio brevi obconico cartilagineo

[Our specimen, also collected by the Rev. Mr. Vachell, and under the same number from Professor Hens- 

 low, does not quite agree with the above description ; we, therefore, insert also the specific character we had 

 drawn up previously to receiving that by Prof. Nees von Esenbeck : — Culmo (apicem versus saltern) aphyllo 

 glaberrimo laevi tereti-compresso apice uniangulato, rachi leniter flexuosa, spiculis oblongis in spicis densis 

 dispositis, spicis erectis inferioribus compositis ovato-oblongis breviter pedunculatis mediis subsessilibus, 

 ovatis superioribus simplicibus confertim glomeratis, bracteis pruniosis omnibus spica propria multo breviori- 

 bus, squamis oblongo-lanceolatis, exterioribusobtusiusculis sterilibus, interioribus carinatis acuminatis. — Thus 

 the principal difference consists in the lower partial spikelets of our plant being peduncled, and forming a 

 kind of panicle.]

Culmus 1-2-pedalis altus, basi bulbosus, et purpureus. Folia inferiora culmum aequantia, 2 lineas lata, 

 floralia 4-3 pollices longa, 2 J lineas lata, omnia apice attenuata, apice ipso obtuso. Panicula axillares, 1-3, 

 saturate purpureas, 1J-2 poll, longas, basi ramosa?, apice ramisque simpliciter spicatis. Bractea subulate, 

 basi dilatata purpurea, pilis rigidis ciliata. Spicula geminte, conferte. 



[To the description and character given by Prof. Nees Von Esenbeck, we may add that the caryopsis is at 

 first only slightly rugulose, the elevated parts being covered with numerous short bristles i afterwards it is 

 almost or quite glabrous ; the lobes of the hypogynium are obtuse and not more than one-fourth the length 

 of the caryopsis. The margins of the leaves and sheaths are often only slightly scabrous.]
