varies quite as much as that species does. The diagnoses given above serve to dis- 

 tinguish them, especially the small size of the spikelets of A. tiiUata, its annual habit 

 and the large size of the tubercles on which the far more copious rigid bristles 

 are inserted. Boxburgh describes it as perennial and scandent, with stems many feet 

 long, rooting at the nodes, but Hackel has pointed ont that Roxburgh's descrip. 

 tion is that of an annual j and as I have seen it growing in Bengal, it is rather 

 a scrambler amongst bushes than scandent in a strict sense. The stems are also 

 often erect with a geniculate base.

 only a dwarf Variety of A. ciliata, specimens of which accompany it in Heifer's 

 herbarium.

Stem 3—1 ft., erect, as thick as a small goose-quill, polished. Leaves 1 ft. by 

 J— J in., smooth, tips filiferous; sheaths polished, terete, keeled; ligule a narrow 

 ciliolate membrane. Panicle 1-2 ft., with one or two lower long axillary branches ; 

 leaves of panicle 6-10 in., flexuousj fascicles of spikes triangular, about i in. 

 broad, outer spathes hardly longer than the fascicles cymbiform with very slender 

 tips, glabrous. Invol. spikelets gl. I margins narrowly winged ; II as long, acumi- 

 nate, 3-nerved ; III lanceolate, hyaline, 1-nerved. Bisexual spiielets terete ; 

 callns bearded with white hairs; gl. II coriaceous, notched, awned ; III shorter, 

 hyaline, 1-nerved ; IV the very narrow bifid hyaline margin of an excessively slender 

 awn J in. long; palea minute. Gl. I of pedicelled spikelets lanceolate, keels with 

 long stiff tubercle-based hairs. — The long panicle and very small heads with short 

 spathes, and the strongly armed gls. of the invol. and pedicelled spikelets distin- 

 guish this from A. imierhis, and ally it to ciliaris with which it agrees in the size 

 and armature of the spikelets.

Perennial? -Stem tufted, 1-3 ft., rarely thicker than a crow-quill. Leaves S-12 

 in., finely acuminate, nearly smooth, margins scaberulous, upper often exceeding 

 the panicle j ligule a narrow membrane. Panicle 1-2 ft., subsimple, of many usually 

 distant compound fascicles of spathes and spikes on flexuous capillary peduncles \-\ in. 

 long ; lower branches sometimes elongate and again panicled ; fascicles red brown 

 when dry, the larger sometimes semiglobose ; outer spathes usually hardly longer 

 than the fascicles, proper spathes not twice as long as the spikes, sides and keel ciliate.
