is usually ascending, but in the lower part of the spikelet sometimes 
spreading. Bristles 0 or very minute. Achene brown, smooth, a as

Mauritius, in swamps at Pamplemousses, etc. F. mauritiana, Nees ; Kunth, 
Enum. iii. 186, is apparently a form without the awn to the glumes. Our specimen of 
Sieber, Herb. Maur. ii. No. 1, has it as usual. F. Thouarsiana , Kunth, iii. 186, is 
probably another variety in which the bristles are developed. The Indian F. 
pentagona, Wight, appears another variety of the same species, which is spread 
through the tropics of both hemispheres.
