CXLIT. GRAMINER. 4A. 
20. SPODIOPOGON, Trin. 
Spikelets in pairs along the jointed, angularly-compressed 
rachis of simple or branched spikes, 1 subsessile, the other 
pedicellate, both 2-flowered ; the lower flowers male. Outer 
glumes rigid, often hairy ; the lower several-nerved (sometimes 
2-fid); the upper keeled, pointed or 2-fid and setigerous. 
Flowering glume and palea thin and membranous, the glume 
of the fertile flowers 2-fid, with a twisted awn.—Wees, l.c. p. 
96; Benth. Fl. Hongk. p. 426. 
S. arcuatus, Nees, a grass with leafy culms, the leaves flat and much- 
Bee and bearing 2-3 fulvous spikes, is found in British Caffraria 
and Natal. 
21. TRACHYPOGON, Trin. 
Spikelets cylindrical, in pairs along the slender rachis of 
solitary or tufted spikes; the lower male, pointless ; upper 
female, awned. Lowest outer glume several-nerved; the 
next narrower, 8-nerved; a third empty hyaline. Flow- 
ering glume (in the fertile spikelets) very thin, narrowed at 
base, then linear-expanded, obtuse and ending in a long, more 
or less hairy, twisted awn.—Wees, l.c. p. 99. 
T. Capensis, Nees, has a culm 1-2 feet high, flat, narrow leaves and soli- 
tary spikes. 
22. ELIONURUS, Kth. 
Spikelets pointless, in pairs along the jointed axis of a 
simple spike ; one male or neuter, pedicellate ; the other ses- 
sile, with a hermaphrodite flower. Two outer glumes of the 
fertile spikelets rigid, but thin; the outer much larger, many- 
nerved, taper-pointed or 2-fid, silky without, the second 
smaller, keeled, entire ; third also empty, shorter and thinner. 
Flowering glume still thinner, convolute. Scales truncate. 
Grain compressed, free.—Vees, l.c. p. 94. 
Rigid grasses, with filiform leaves and nearly nude culms, ending in a 
silky and silvery spike.— Nees has 2 species, one of which, #. argenteus, is 
common in the Eastern district and at Natal. 
23. VOSSIA, Wall. and Griff. 
Spikelets in pairs on each excavated joint of a flattened- 
jointed spike ; sessile spikelets slightly sunk in the rachis, 2- 
flowered, lowest flowers male; upper fertile, both very mem- 
branous or transparent, pedicellate spikelets also 2-flowered ; 
both flowers male or occasionally neuter, similar to those 
of sessile spikelets. Outer glumes 2, dissimilar, the outer 
very thick, in the pedicellate spikelets always, and in both
