lepidibus, Maio 1860, по. 68790; in arvis post Sorghi plantationes, nimis frequens 
prope Lopollo, по. 6854.

С. ($ PycREUS) PELOPHILUS, n. sp. Czspitosus, radicibus tenuibus; culmis ssepius pluribus 
patulis, subpedalibus compressis apice triquetris striatis; foliis linearibus angustis, 
culmis multo brevioribus flaccidis, vaginis fissis membranaceis striatis purpureo- 
punctatis ; umbella szepius magna diffusa, radiis valde inzequalibus, longissimo eorum 
4-unciali, ocreis ore truncatis seepius laminiferis basi purpuratis; spiculis aggregatis 
multifloris linearibus uncialibus patentibus ; foliis involucralibus 6, linearibus flaccidis 
radios subeequantibus, apicibus remote spinulosis scabriusculis; rhacheola angusta 
flexuosa, foveolis angustis oblongis; squamis remotis ovatis lanceolatis, brevissime 
mucronulatis 5-nerviis flavis, carina viridi; stylo bifido tenui haud exserto; caryopsi 
obovata compressa brevissime apiculata, nigro-brunnea, squama 3 breviore. 
Mossamedes, in paludosis arenoso-argillaceis prope Giraul, sparsim, no. 6887. 
Loanda, ad stagna exsiccata in via versus Calumba prope Cumano, initio Julii 1860; in 
arenosis inundatis exsiccantibus prope Bemposta, Julio 1858, no. 7025; in argillaceis 
stagnorum exsiccatorum prope Forte de Conceiao satis frequens, Julio 2, 1854, no. 7082. 
The caryopsis in this plant is remarkably flattened laterally, very much like the seed 
of ап ris. The spikelets in no. 7082 are faleate, owing to some injury, probably 
due to an insect.

erectis pedalibus vix triquetris canaliculatis ; foliis culmo duplo brevioribus rigidis 
linearibus angustis, acutis patentibus apice scabris, vaginis truncatis amplis minute 
purpureo-punctatis ; foliis involucralibus 3-linearibus acutis patentissimis, basi vix 
dilatatis, marginibus scabridis, imo triunciali, cæteris brevioribus ; radiis umbellæ 
inæqualibus brevibus obtuse trigonis canaliculatis, spicis oblongis, spiculis lanceolatis 
acutis patentibus trilinealibus ; ocreis brevibus truncatis sæpius brevi lamina munitis ; 
bractea parva lanceolata acuminata in basi spiculis infimis ; squamis lanceolatis 
acutis atro-sanguineis, carina viridi; stylo profunde bifido, brevi, pallido, parum 
exserto; caryopsi (immatura) minuta squama $ breviore, obovata fusiformi bicon- 
vexa, mucrone longo; staminibus tribus linearibus; rhacheola subflexuosa, foveolis 
brevibus angustis oblongis. 
Huilla, in pascuis uliginosis inter Ferrao da Sola et J ati, unico loco sat frequens, April.
