126 MR. H. N. RIDLEY ON THE WEST-AFRICAN 
C. ($ Русвкиз) FULVUS, n. sp. Glaucus, rhizomate repente lignoso, crassiusculo, radici- 
bus crebris validulis ; culmis semipedalibus rigidis striatis obtuse triquetris basi dila- 
tatis; foliis rigidis linearibus acutis carinatis, culmo brevioribus; involucralibus 
tribus rigidis linearibus acutis, demum patentibus basi vix dilatatis longis ; umbella 
plerumque congesta ; spicis pluribus, ultra viginti; ramis flexuosis triquetris brevi- 
bus, squamis ad 13, lanceolatis trinerviis carinatis breviter mucronatis lucidis fulvo- 
brunneis ; carina viridescente, marginibus crispis anguste scariosis ; staminibus tribus 
_ breviter apiculatis; stylo bifido parum exserto; caryopsi immatura minuta. 
Huilla, in humidis inter Lopollo et Eme ad oras sylvarum frequens ad finem Aprilis, 
no. 6872 : in agri Lopollensis arvis humidis olim dumetis juxta rivum, no. 6881. 
The affinity of this plant is with C. intermedius, Steud. The umbel is usually compact 
as in that species, but where it is not, the involucral leaves spring from the base of each 
ramus, and do not form a whorl, as in most Cyperi. А similar arrangement obtains also 
in C. stramineus, Nees, etc., but less conspicuously, and it is carried to an extreme in the 
allied C. divulsus, Ridl., where the inflorescence is actually a compound spike, each 
flower-spike, with its subtending leaf, being sessile on the produced primary rhachis. The 
brown shining leaf-sheaths break up by decay, leaving the bulbous base of the stem 
covered by the black wiry fibro-vascular bundles. Height of culm 5-7 inches; leaves 
2-5 inches high by 1 line in diameter; spikelets 4 lines in length; involucral leaves 
attaining the length of 2 inches.

С. ($ Русввов) LANCEUs, Thunb. Prod. p. 19, var. angustifolius, n. var. Rhizomate 
gracili descendente aut stolonifero; culmis bipedalibus, gracilibus; foliis elongatis ; 
culmis brevioribus, anguste linearibus ; involucralibus 2—8 similibus. 
Pungo Andongo, Candumba, Mart. 1857, no. 6950. 
The slender leaves and rhizome give this plant a very different appearance from the 
typical form, which it otherwise resembles. Тһе species is found at the Cape, and Nuer 
White Nile territory and Madagascar.
