Perennial, 23 ft. high, with a tuft of spreading branching shoots ; 
leaves patent, linear-lanceolate, acute, with rigid minutely aculeate 
margins ; spikes short, distant, sessile ; spikelets few, turgid, closely 
arranged in two rows on a slender flexuose rachis, 1} line long,

fertile gl. nearly equal to the last, obovate, enclosing a 8 flower. 
A number of shoots spring in a tuft from the short hard

ascending branches finally erect, and ending in long subfiliform 
spike-bearing axes; nodes puberulous. lLeaf-sheaths generally
