 cribed on p. 259 of my C.P. List, which are apparently montanus, Trin. 

 (described below) or monticola proper of the F.B.I., and robustus 

 (see below) : 



J. Sessile spkts. -IG-'i" loiio- : — 



A. Leaves ■l-'2" wide only: — 



1. Leaves S'lfi^irous on tlie surfaces : — 



Slender 2-3 ft. L. eciliate. Panicle 2-3". Gl. i 



and ii of sess. spkt. scabrid or ii witli few 



bristles. Ped. spkt. hispid all over 'lo" long-, 



both awned a. scahrida. 



Gya, Rajmahal Hills. (C. serrulafns, Trin,?) 



Slender 3-4 ft. L. with long- tubercle-based 



cilia towards the base. Panicles 3-±". Gl. i 



with few short hairs at tip ; ii with a ridge of • 



bristles in the central three-fourths of back. 



Ped. spkt. '2" nearljr glabrous, not awned . 13. rnonianus, Tri». 

 Saidope Forest, Palamau. 

 •2. Leaves pubescent on the surfaces : — 



Panicle i", rhachis pubescent. Gl. i scabrid- 



ciliate on nerves; ii bristly along back and 



the bristles extending on to the awn . . y. puhescenf. 

 Parasnath. 



B. Leaves •3-'4" wide, somewhat glaucous beneath :— 

 Panicle 5-6". Gl. i hispid at tip, much shorter 



than ii ; ii with red bristles on the back. Ped. 

 spkt. awned or not. This is perhaps rohustns 



of F.B.I., but the leaves are much broader . 5. rohustus, J.D.II. ? 

 Palamau. 

 II. Ses.sile spkt. •25-"3" long : — 



Tall, up to 6'5 ft. and -25" diam. at base, lower leaves

 times ciliate, young glaucous beneath, upper 

 surface puberulous or hispidulous. Panicle (spkt.s.) 

 pink lanceolate 5-G". Sess. spkt. gl. i 2-dentate 

 or minutely 2-cuspidate, hard ; ii '0.5" broad at 

 sides, bristly above base, awn •2.5--3" long; iii "22"

and pedicels yellow e. 2}(iJ(f'"inni)i'if.

 This last is possibly a distinct species. Hole .states that all the forms he ha.s 

 fseen apparently pass into one another. 

 The grass is a valuable fodder. 



72. DICHANTHIUM, Willem. 



Perennial or annual usualh^ slender ciespitose grasses with narrow 

 leaves and short ligules, or ligule of hairs. Spikes solitary or in sub- 

 digitate panicles with a short primary axis, rarely spikes 2-3 on the 

 .short branches of panicle, branches or spikes shortly peduncled. 

 Spikelets often subimbricate, 2-nate, sessile and pedicelled similar 

 in shape or nearly so, lowest one or two paii's also homogamous, male or 

 neuter, others differing in .sex. Joints and pedicels filiform, without 

 thin translucent centre, articulations more or less transverse. Sessile 

 .spkts. dorsally compressed, callus short rounded shortly bearded or 

 glabrous. Glumes 4, i usually oblong obtu.se 2-keeled with margins 

 narrowly inflexed ; ii much narrower cymbiform 3-nerved, 1- or 3-
