Susrrise VIL. CHLORIDEAE. 
Spikelets sessile on one side of spikes which are either solitary or 
digitate or scattered on a common rhachis, laterally compressed, 1- to 
several - flowered, with one or more of the upper florets imperfect, arkiculate 
above the persistent empty glumes. 
25. CYNODON, Pers. 
Spikelets 1-flowered, awnless, singly sessile in 2 rows on one side of 
slender spikes which are digitate at the end of the stem. Outer empty 
eeled. ea 
narrow, bicarinate, with a small bristle at its base. yles distinct, ter- 
a with elongate stigmas. Grain free, not furrowed. 
A genus of 4 species, the following one — over the warmer regions of the 
whole world, the 3 remaining ones Australia 
+1. C. dactylon, Pers. — Kunth, Enum. PI. I, 259. — Stems creeping and 
rooting, dividing freely, the ascending flowering branches 6—12‘ long, 
weak, compressed, naked in the upper portion. Leaves linear, flat, 4—1’ 
long, glabrous, the ligule consisting of long ciliae. Spikes 3—5 at 
end of the stem, each 1—1'/2‘ long, their rhachis narrower than the 
aeons Spikelets ovate, 1—1'/4”. Empty glumes subequal, the oh 
shorter, narrow lanceolate, nee glabrous. Flowering glume 
ilies and nih broader, obtusely boat-shaped, rather chartaceous, with 
1 median and 2 marginal nerves, the keel often ciliate with softish hairs.

26. CHLORIS, Swartz. 
Spikelets with 1 fertile floret and 1 or more empty or rudiment 
glumes above it, singly sessile in 2 rows on one side of simple uh 
either solitary or several digitate at the end of the stem. Glumes thin, 
keeled ; the 2 outer empty ones pointed, or the second shortly awned; the 
flowering one 3-nerved, mostly ciliate on keel and margins, produced into 
a fine straight awn; the upper empty ones often awnless and usually with 
their ends on a level with that of the flowering one. Styles distinct. 
Grain free, elongate, trigonal, with a thin, often loose pericarp. 
A large tropical genus, common to the Old and New World. 
1. C. radiata, Sw. — Kunth, Enum. Pl. I, 265. — Tufted. Stems erect, 
re ft. high, compressed, glabrous, branching below, the uppermost leaf 
a short distance from the panicle. Leaves subopposite and distichous
