140 MR. H. N. RIDLEY ON THE WEST-AFRICAN 
Some very small and young plants, about 1 inch in height, may perhaps belong to this 
species; they are labelled “ Huilla, in campestribus olim Solano tuberoso satis, nunc 
neglectis, sparsim, rhizomate tuberifero, initio Maii 1860, по. 6865." They seem to have 
sprung from bulbils, and, though none of the other specimens are bulbilliferous, as they 
seem in all other respects except size to be identical with this plant, I am inclined to 
refer them to it. 
C. actinostacHys, Welw. MSS. Cæspitosus, glaucus, radicibus copiosis, tenuibus ; culmis 
erectis crassiusculis ultra pedalibus striatis obtuse triquetris; foliis linearibus rigidis 
recurvis culmo multo brevioribus, vaginis longiusculis truncatis sæpius fissis purpu- 
rascentibus striolatis ; involucralibus circa 6, linearibus longis recurvis basi dilatatis ; 
umbella simplici, radiis valde inzequalibus patentibus; ocreis brevibus truncatis 
purpureis; spiculis pluribus congestis patentibus linearibus multifloris ; squamis 
lanceolatis breviter mucronatis remotiusculis trinerviis, carina viridi lateribus atro- 
purpureis, costulis pallidis; stylo gracili trifido parum exserto, rufescente; caryopsi 
oblonga obtusa trigona atra. 
Huilla, in sylvis mixtis claris, Monino, ad finem Martii, no. 6874; in arena calida ad 
ripas fluminis Cuanza prope Candumba, Jan. 30, 1857, no. 6928, no. 6931. 
The spikelets are aggregated in capitula at the extremities of the rays of the umbel, 
radiating from the centre as in C. dilutus, Vahl, whence the specific name. Тһе invo- 
lucral leaves are about 8 inches in length, and usually purple at the base. 
C. ANDONGENSIS, n. sp. Glaucus, radicibus copiosis fibrosis; culmis obtuse triquetris 
ultra pedalibus gracilibus erectis rigidis striatis; foliis pluribus angustissime linearibus 
semipedalibus; marginibus scabridis, vaginis membranaceis brunneis fissis; involu- 
eralibus 3—4 angustis linearibus patentibus, basi vix dilatatis; umbella compacta, 
radiis szepius brevissimis ; rhacheola subflexuosa angusta, foveolis angustis oblongis ; 
spiculis pluribus linearibus ; squamis remotiusculis atrosanguineis trinerviis oblongo- 
lanceolatis obtusis brevissime mucronatis lucidis; stylo profunde trifido, caryopsin 
sub:quante vix exserto, rufo; caryopsi oblonga, basi angustata breviter apiculata, 
nigra punetata, squama duplo breviore. 
Pungo Andongo, in arena calida ad ripas fluminis Cuanza, prope Sansamanda, Feb. 
1857, no. 6929. 
Culms erect and stiff, but slender, 1$ foot high; leaves narrow, stiff, and wiry, almost 
setaceous, with broader polished brown bases; the spikelets unusually long and narrow.
