54, Cyrtococcum, Stapf in Prain Pi. Trop. Afr. ix, 745. 



Perennial. Culms weak, rising from a decumbent or creeping and rooting 

 base. Leaf-blades flat, linear-lanceolate or almost linear. Ligules membranous, 

 short. Spikelets on long to very long and capillary or short pedicels, widely 

 scattered or approximate, obliquely obovate to semi-obovate, laterally much 

 compressed, falling entire from the pedicels of very loose and open or contract- 

 ed and dense panicles. Involucral glume thinly membranous, unequal to 

 subequal, 3-5 nerved. Lower floret barren with or without a pale, glume 

 similar to the upper involucral glume, pale, if present, narrow, 2-nerved. 

 Upper floret about as long as or almost as long as the lower, hermaphrodite, 

 glume narrowly boat-shaped, papery to subcrustaceous with firm very narrowly 

 involute margins, obsoletely 5-nerved ; pale subequal to the glume, with a 

 narrow convex back, of the same substance as the vaJve, with fine keels and 

 thin flaps. Lodicules two, minute, broadly cuneate. Stamens three. Styles 

 distinct ; stigmas sublaterally exserted high up. Grain not known. 



Species 6 or 7. Tropical Africa, Indo-Malaya. 



None of the species here described were mentioned by Cooke. Hook, f . in. 

 F.B 1. has them under Panicum, sect. Gibbosce.

 \ the length of the lower floral glume, obtuse or acute, 3-nerved, pale brown ; 

 upper pale brown. Lower floral glume 5-nerved, pale brown ; upper naked or 

 bearded at the tip.

Description : Perennial. Culms 30-60 cm. high, geniculately ascending from 

 a slender, creeping, branching base, lower nodes rooting, upper subpubescent. 

 Leaves 5-15 cm. long, 8-35 mm. broad, glabrous or sparsely hairy above, 

 puberulous beneath, finely acuminate, base narrow. Sheath glabrous or ciliate, 

 mouth hairy. Ligule rounded. Panicle 7-13 cm. long, contracted, branches 

 short, rather remote, erect or spreading with short fastigiate branchlets, often 

 slender hairs on the pedicels. Spikelets 1'5 mm. long, brown, very shortly pedi- 

 celled, glabrous. Lower involucral glume about h the length of the lower 

 floral glume, obtuse, 3 nerved. Lower floral glume 5-nerved ; upper white, its 

 pale narrow, patent, hard.
