bearing glume without glands; keel wingless, scabrous. Nut 3-3 the 
length of the glume, oblong, finally black.—X. spherocephala, var. 
brunnescens, C. B. Clarke in Durand & Schinz, Conspect. Fl. Afr. 
v. 5382. 
Upper Guinea. Upper Senegal, Lécard, 215. 
The short thick rhizome, as well as the 5 cylindric heads, negative this plant 
being arranged under K. sph erocephala, Boeck. 
15. K. melanosperma, Wees in Linnea, ix. 286. Rhizome thick, 
$-1} in. long. Stems 20-30 in. long, triquetrous under the inflores- 
cence. Leaves much shorter than the stems, often 4—6 in. long, }-} in. 
broad. Head of 1 spike, ovoid, dull green, $ in. long and more; 
bracts 3—4, similar to the leaves, the lowest often 4 in. long. Spikelets 
numerous, }-} in. long, each producing 1 (very rarely 2) nut. Nut- 
bearing glume ovate, acute; keel not winged, almost smooth. Nut }—3 
the length of the glume, narrowly obovoid, finally black.—Nees in

The plants with the ticket “ Stuhlmann, 93,” are by some error in distribution 
marked Rhyncospora echinophora, K, Schum. ; but I have not found where that 
Rhyncospora is published. In Cameron, 89, the stems exceed 5 ft. in height; the 
heads are young and I do not see how they differ from young heads of K. melano- 
sperma. 
16. K. pungens, Link, Hort. Berol. i. 326. Rhizome horizontal, 
thick, closely covered by ovate rigid brown scales. Stems 8-18 in. 
long, rather stout, contiguous and uniseriate on the rhizome. Leaves 
3+} in. broad, less than } the length of the stem, often quite short. 
Head of 1 spike, }-} in. in diam., dense, subglobose ; bracts generally 
4, sometimes 5, 1—4 in. long, similar to the leaves. Spikelets ;',—} in. 
long, each perfecting 1 nut. Keel of the nut-bearing glume slightly 
Scabrous, not winged. Nut scarcely 3 the length of the glume, finally 
black.— Kunth, Enum. ii. 128; C. B. Clarke in Durand & Schinz,
