The DECCAN, Hnyne. PULNEY HILLS, Herb. Wight (n. 3338). 



Stem erect from a tuberous rhizome which is .clothed with the woolly bases of 

 leaf-sheaths. Leaves 6-12 by i- in., acuminate, base rather narrow ; upper sheaths 

 glabrous ; ligule a ridge of hairs. Panicle 5-7 in., flexuous; rachis filiform, scaberu- 

 lous; branches few, 4-6 in., naked below except a solitary long-pedicelled axillary 

 spikelet ; pedicels capillary. An obscure plant. Nees describes the leaves as with 

 pparsely setulose margins, and gl. IV as mucronate, from which it is evident that 

 the awn has fallen away in his specimen. This latter suggested the name mutica, 

 which, being misleading, I have replaced by Heyne' s of capillaris. Wight's Pulney 

 sperimens have a slightly hairy panicle 3 in. long, with more numerous close-set 

 bra.iches and closer spikelets. Lisboa (Journ. Bomb. Nat. Hist. Soc. v. .(1890) 

 344) gives mutica as a common plant all over Bombay, but without seeing specimens 



I cannot confirm this. 



16. A. laxiflora, Hook. f. ; very slender, glabrous, leaves narrow, 

 panicle effuse, branches spreading capillary solitary alternate or opposite 

 or the lower fascicled, branchlets spreading, spikelets |- in. solitary 

 shorter, than their capillary pedicels, gl. I = II ovate acuminate 3-nerved, 



II ovate-lanceolate 5-nerved, III longer than I oblong acute, IV longer 

 than III oblong-lanceolate scaberulous, awn or shortly exserted. A.

CEYLON, Gardner ; Central Province, alt. 3-5COO ft., Thwaites (C.P. 919). 



Annual ? glabrous. Stem 12-30 in., tufted, geniculately ascending, nodes glabrous- 

 Leaves 4-8 by - in., finely acuminate ; ligule narrow, membranous, ciliate.. 

 Panicle 4-6 in., green. Gl. 1 scabrid on the keel or not ; IV bearded at the base or 

 Dot ; column of awn twisted. The open panicle with long capillary pedicels of the 

 spikelet and quite acute gl. Ill which is | longer than I, characterize this species. 

 One specimen ( Gardner, n. 1007) has no trace of au awn. 



*** Awn 0, or very short and hardly exserted (see also A. laxiflora).
