middle one is the largest, and often compound ; all are more 
or less recurved, very strong, and sharp, By the number 
and strength of these spines, and of the branches of this 
species, it may be said to form the most impenetrable 
jungle in India. Leaves sessile on their sheaths, bifari- 
ous, linear-lanceolate, cuspidate, rarely more than six 
inches long. ‘The sheaths have their mouths ciliate with 
hairs and filaments. 
Inflorescence. The plants of the clump when in flower,

ed on the joints of the extreme branchlets, sessile, lanceo-— 
late, generally three, four, five or six-flowered, &c. ex- 
actly as in Poa. Florets the inferior two and terminal 
one male hermaphrodite, or neuter, the middle two, or 
three, or four hermaphrodite. Calyx, the number of scales 
which embrace the base of each spikelet uncertain, Co- | 
rol ; glume, two-valved ; exterior smooth, hard, and point- 
ed ; inner as long as the exterior, concave behind; margins 
incuryed, forming one acute angle, asin Poa ; edges 
of the posterior concavity much ciliate. Nectary of three, 
 Corol-like, oval, ciliate scales, Filaments six, three im- 
mediately within the nectarial scale, and three alternate 
with them. Germ clavate. Styles three, cuninnl pees 
with pale purple wool. :
