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

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

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

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

 long, rooting at the nodes, but Hackel has pointed out tbat Roxburgh's descrip- 

 tion is that of an annual ; 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. 



Var. Helferi ; dwarf, spikes in more compact globose heads. A. Helferi, 

 Munro mss. Themeda Helferi, Hack. I. e. 665. Tenasserim, Heifer. I think this is 

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

 herbarium. 



5. A. strigrosa, Ham. mss. ; perennial, stem tall rather stout, spikes 

 in small dense shortly peduncled heads arranged in a long very narrow 



eiicle with filiform leaves, spathes very short glabrous, invol. spikelets 

 in. gls. 3 dorsally clothed with very rigid tubercle-based bristles, 

 5xual spikelets 1-2 i- in. hispidulous towards the tip, callus short 

 obtuse, awn very short capillary. Anthistiria, Wall. Cat. n. 8766.

Stem 3-4 ft., erect, as thick as a small goose-quill, polished. Leaves 1 ft. by 

 g i \ 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., flexuous; fascicles of spikes triangular, about 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 spikelets terete ; 

 callus 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 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 

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

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

 and armature of the spikelets.

Perennial ? Stem tufted, 1-3 ft., rarely thicker than a crow-quill. Leaves 6-12 

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

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

 distant compound fascicles of spathes and spikes on flexuous capillary peduncles |-1 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.
