Eacemes 1 to 1.^, in. long, terminal and lateral on long thread- 

 like branches from the uppermost nodes, protruding from their 

 stalked rufous narrowly lanceolate acuminate spathes ; rhachis 

 brittle, joints (Irj line long) with irregularly dentate cup-like 

 apex; sessile spikelet 31 lines long; callus short with a small 

 tuft of hairs ; gl. I. 3] lines, greenish-red ; gl. II. 4^ lines 

 including the awn (2 lines), bhuit, widest at or a little above the 

 middle ; gl. III. lanceolate, 2 -nerved with edges incurved at 

 the nerves, 2.} lines; fertile glume partite to about the middle, 

 2 lines long, the strong awn springing from between the two 

 acute points, brown and twisted below, kneed below or about 

 the middle and passing into the pale slender flexuose subula ; 

 pale short, truncate, scarcely 11 line ; lodicules large fleshy, 

 obliquely cuueate, 1 line long. Pedicel ItV lines long, apex 

 dentate as in the rhachis-joint, its stiffish hairs reaching }.- way 

 up the outer glume which including the awn is 4 lines long, 

 minutely hispidulous on the back and inconspicuously 9-nerved, 

 the median awn exceeds the two lateral ; gl. II. 3 lines long, 

 5-nerved, reddish ; gl. III. 21 to 21 lines, 2- to 3-nerved ; gl. IV. 

 2 to 21 lines, 1- to 3-nerved, pale as in sessile spikelet; anthers 

 reddish, linear, 11 lines long; lodicules as in sessile spikelet. 



An interesting addition to the subgenus which hitherto has 

 contained only the widespread tropical A. fastlgiatus Sw. Fi'om 

 this A. textilis is distinguished by its stifFer habit with more rigid 

 leaves, its smaller more compact spikes, the less difference in size 

 between sessile and pedicelled spikelet, and the smaller more rigid 

 outer glume of the latter. Other differences are found in the 

 approach to equality of the outer and inner barren glumes of 

 the stalked spikelets, and tlie more membranous shorter-awned 

 and more oval inner barren glume of the sessile.
