spikes; spikelets many-Hflowered, (5 or 6) ovate, or Ian- 
ceolate, somewhat resembling those of Poa, but more 
compressed; valves of the calix and corolla similar, and 
nearly equal, persistent; outer valve of the calix about 9-

‘The very few genuine species of this genus are found — 
in India, Barbary, and North America. The Cynosurus

Spikes paniculate, filiform; spiculi 3 to 4- 
flowered, alternating on a l-sided racnis.— 
Common calix 2-valved, subulately acuminate,

valves uninervial. - Corolla 2-valved, minute, 
deciduous, valves obtuse, with or without a ter-

An American genus of grasses existing chiefly within 
the tropics; nearly allied to Eleusine, but producing long 
filiform spikes, disposed in panicles; leaves, in some spe- 
cies, scattered with glandular hairs; the cahx and flowers 
_of different forms, and the jatter decidous with the seed, 
which is naked, nearly spherical and smooth.
