1G. Lasiurus, Boiss. (Stapf in Fl. Trop. Afr. ix r 60) 



Perennial, more or less branched and woody below ; branches often in dense 

 fascicles, intravaginal. Leaves linear, convolute or flat, hard ; ligule a fringe 

 of hairs. Racemes silky-viHous. Spikelets usually 3-nate, rarely 2-nate, on 

 the more or less fragile rhachis of villous spike-like racemes which end the 

 stems and branches (if any) and are supported by or exserted from often 

 spathaceous sheaths, if 3-nate 2 sessile, the. sessile different in sex from, but 

 similar in shape to, the pedicelled ; rhachis nodes bearded all round ; joints 

 and pedicels linear, the latter more slender and shorter, opposite the joints if 

 2 sessile spikelets be present, otherwise approximate, but not contiguous and 

 parallel to one of the sides of the joint ; disarticulation at a right angle to the 

 rhachis, scar at the tips of the joints suborbicular, smooth, often ciliate. Sessile 

 spikelets, if 2, one on each side of the pedicel with a narrow ring-shaped callus. 

 Florets 2, lower male, upper bisexual, awnless. Glumes unequal ; lower 

 longer, subcoriaceous, flat on the back, acuminate, 2-keeled upwards and 

 2-dentate, densely ciliate, upper boat-shaped, membranous, keeled. Valves 

 hyaline, 3-nerved. Valvules hyaline, 2-nerved. Lodicules 2, cuneate. Stamens 

 3. Stigxas linear, laterally exserted. Grain oblong, slightly dorsally com- 

 pressed, embryo half its length. Pedicelled spikelet similar to the sessile, but 

 with an indistinct glabrous callus and with both florets male or more or less 

 reduced,

17. Rlyonurus, Humb. and BoupL (Stapf in Fl. Trop. Afr. ix, 62) 



Usually perennial, csespitose, aromatic grasses. Blades of leaves flat or 

 folded ; ligules very short, membranous. Racemes erect, joints strongly 

 compressed, usually villous, tips oblique, not appendaged. Spikelets similar, 

 usually awnless, differing in sex, 2-nate, one sessile, the other pedicelled, on 

 the articulate fragile rhachis of solitary spike-like racemes, the sessile deciduous 

 with the adjacent joint of the rhachis and the pedicel. Florets 2 : Lower 

 reduced to an empty valve, upper bisexual in the sessile male, rarely barren, in 

 the pedicelled spikelet. Glumes equal : Lower subcoriaceous to herbaceous, 

 often 9-toothed or 2-fid, rarely awned, dorsally flattened, 2-keeled, usually 

 with fine filiformed transparent balsam ducts close to the ciliate or penicillate 

 keels ; upper membranous, lanceolate, acute, rarely awned. Valves hyaline, 

 awnless. Valvule obsolete or absent. Lodicules 2, cuneate. Stamens 3. 

 Stigmas laterally exserted. Grain oblong, dorsally compressed ; embryo about 

 half the length of the grain. 



Species about 15. — Tropical and subtropical regions of both hemispheres.
