hills. This form appears to me to be most nearly allied of any in habit and 

 spikelets to Pasp. ambiguum. 



Var. 2. commutatum ; usually tall, stout or slender, tufted or prostrate and 

 widely creeping below, leaves rather long, spikes few or many (up to 20) 3-6 in. 

 long fastigiately or subcorymbosely arranged, lower often whorled or fascicled, 

 rachis slender narrowly winged, spikelets broad rather crowded shortly pedicelled, 

 gl. I lanceolate rather shorter and narrower than III, II with the lateral nerves 

 glabrous or pubescent, and with usually a minute gl. at the base, III lanceolate 

 acuminate. Pan. commutatum, Nees in Serb. Royle ; Digit, ciliaris ? Wight Cat.

 I.e. P. filiformp, Roxb. Ic. ined. Throughout India, especially in the hills, 

 ascending to 7000 ft. along the Himalaya, and to 10,000 in Western Tibet. 

 (Asia, Africa.) This is the typical S. African Pan. commutatum, Nees, but 

 I am doubtful as to its being the P. corymbosum, Roxburgh, which is 

 described as found " only in valleys of the Circars, growing to a great size in 

 standing waters, with culms creeping, or floating with their erect extremities 

 above water; when found on dry ground it is in general 14 ft. high, Roxb." A. 

 specimen of var. commutatum in Herb. Kew is labelled Pan. filiforme in Roxburgh's 

 handwriting, but probably the ticket is misplaced. 



Var. 3, ciliare ; usually tall, slender, spikes few (2-6) 3-6 in. long, rachis 

 slender narrowly winged, gl. I long or short ciliate, gl. II of lower spikelet, with 

 glabrous or sparingly villous, marginal nerves, of tipper spikelet with the marginal 

 nerves densely villous or bearded with soft spreading hairs that are much-broader 

 than the gl. and often hooked at their tips. P. ciliare, jRetz.; Wall. Oat. n. 

 8682). Digitaria ciliai'is, var. quadristachya, Wight Herb. n. 3034. D. commu- 

 tata, Herb. Strach. 8f Winterb. n. 2. The bearded glumes may occur in other of 

 the varieties here enumerated (as in var. debile from the Nicobars) as it is only 

 when the spikelet is well advanced that the beard appears to be fully developed. 

 Very common. 



Var. 4,pabulare; perennial, tall, strict, erect, spikes very many 3-7 in., rachis 

 slender trigonous, spikelets rather distant narrowly lanceolate acuminate silkily 

 villous white, gl. I as long as III 3 -nerved, II with approximate nerves and 

 usually a minute accessory gl. at its base, III very narrow acuminate. Pan. pabu- 

 lare, Aitchis. 8f Hemsl. 1. c. The lower hills of the Panjab, Affghan,istan, and Belu- 

 chistan, Jacquemont, &c. 



Var. 5, pruriens ; erect, glabrous, or sheaths hirsute, spikes many 3-5 in., rachis 

 slender trigonous, spitelets narrowly lanceolate acuminate nearly glabrous, gl. I 

 nearly as long as III, II very narrow, with approximate nerves and a minute 

 basal gl., Ill very narrow acuminate. Pan. pruriens, Fisch. 1. c. Bengal, Wallich 

 (Cat. n. 8681, L.). Burma, Griffith, Malacca, Cuming (n. 2397), Maingay (Kew Distrib. 

 1729), (Java. &c.). Hardly different from var. extensum. 



Var. 6, Griffithii; spikes several 2-4 in. long very slender often drooping, rachis 

 filiform trigonous, spikelets linear-lanceolate solitary or in distant pairs glabrous or 

 ciliate, pedicel of upper often longer than the spikelets, gl. I nearly as long as III 

 narrow 5-nerved ciliate, II with ciliate lateral nerves, 111 narrow acuminate. Paui-

 longer pedicelled spikelets. It occurs in S. Africa, and no doubt elsewhere. There 

 is no locality on Arnott's ticket of Griffithii, which is doubtless from the Madias 

 peninsula, he has added to it, Wight Cat. n. 2057, which is Pan. horizontale, var.
