leaves and the 1 head (rarely a leaf-bearing node 3-4 in. above the 
base is present). Leaves often overtopping the stem, almost setaceous 
or up to ;'5 In. broad. Head 4-4 in. in diam., of many lanceolate 
spikelets, rusty-brown ; bracts 3-8, ascending, usually overtopping the 
head, linear, often villous or ciliate on the margins. Spikelets 4-1 in. 
long, of 6-7 glumes; 4 lowest glumes empty, 5th rather larger, con- 
taining a bisexual fertile flower, 6th male or empty. Hypogynous 
sete usually 6, as long as the nut, stiff, scabrid, with upward-pointing 
barbs, sometimes 6-4, weaker hardly 4 the length of the nut. Stamens 
3,anticous; anthers crested. Style long, linear, red, at the top minutely 
2-fid. Nut 3 the length of the glime, biconvex, compressed laterally, 
smooth or sometimes minutely scabrous on the shoulders, dark brown ; 
beak 4 the length of the nut, much narrower than it, short conic, dusky 
straw-coloured or green.—C. B. Clarke in Durand & Schinz, Conspect.

2. R. erinacea, (. B. Clarke in Durand & Schinz, Conspect. F1. 
Afr. v.654. Minutely puberulous-scabrous. Stems 2-2} ft. long, with 
strong lateral offsets at the base, and no nodes between the basal leaves 
(which sheath the stem 8 in. up) and the 1 head. Leaves 8-16 by 
5in. Head 1 in. in diam., with numerous lanceolate white spikelets ; 
bracts 3, spreading, lowest up to 8 by } in., minutely pubescent or 
glabrate. Spikelets very young; no sete found, possibly not yet 
developed. Style long, at the tip very shortly 2-fid—Rendle in Cat.

The style is shown erroneously by Ridley’s artist with 3 linear branches. The 
plant in young flower appears very near a Brasilian Rynchospora (Burchell’s 7023 
in herb, Kew.), but has much longer bracts. 
3. R. cyperoides, Britton in Trans. New York Acad. xi. 84. 
Nearly glabrous. Rhizome short, arising from basal offsets (short 
stolons). Stem usually 1-2 ft. long, carrying 1-25 heads in a loose 
irregular corymb. Leaves long, often overtopping the stem, }—5 in.

lanceolate or elliptic-lanceolate, perfecting 1 or 2 nuts ; lowest 4 glumes
