celled, joints and pedicels rather slender -OS— 09" not clavate (tip only 

 dilated and toothed), villous. Sessile spkt. not tightly squeezed 

 between joint and pedicel nor covered by their hairs, -1.5— 2" long, gl. i 

 oblong-lanceolate flat or slightly concave below, hyaline and nei°^'eless 

 or with 2 green nerves between the keels which are not or very narrowly 

 winged above the middle, scabrous and slightly excurrent, proper 

 margins inflexed throughout. 



In the northern area chiefly. One of the commonest savannah grasses in

Var. a. flexuosus, Hack. (?Jlexiiosus is supposed to be South Indian only). 



Tall with very decompound panicle and slender erect often flexuous branches. 

 Outer spathes 1-25", but much larger and foliaceous on main branches. Spikes 

 unequal about -4 and "o" respectively in spatheoles about -7" long. Longer spike 

 sul)sessile with the lowest pair of spikelets homogamous and the sessile spkt. 

 nearly resembling the pedicelled one VKi" long, and its gl. ii not cymbiform. iv 0. 

 Other sess. spkts. -2", gl. i strongly 2-keeled ending in 2 small cusps above, keels 

 scaberulous towards tip and rather broader but not winged, margins narrowly 

 incurved throughout, back pale flat nerveless (or 2 very oliscure nerves) ; ii cymbi- 

 lorm, Its keel well developed and scabrid above ))ut scarcely winged, tip acuminate ; 

 "'•.', i?-"^*'i^®' cihate ; iv narrow-linear -08". 2-toothed and sparsely ciliate at tip 

 with a fine awn •18--2" long. Grain terete "l" long. 



This IS common in Purneah and the Duars. The joints and pedicels are slender 

 with ciha •05--08" long. Leaves -25" broad. 



Var. /3. grandis, Hack. The following description is from the F.B.I. :— 



Tall stout, L. 2-3 ft. long by -S-'S" wide. Panicle narrow, loosely branched, 

 branches distant often drooping, outer spathes 1-5-3", spatheoles 1-1 •2'', Joints and 

 pedicels shortly ciliate. sessile spkts. •17--2" long, oblong-lane., obtuse, dorsally 

 nat or slightly concave below, keels margined or winged above the middle, nerves 

 obscure, keel of u sometimes shortly winged above the middle, lobes of gl, iv 

 ciliate, awn •3--5", > « • 



Rajmahal, Mokim ! (This was the specimen seen by Hooker.) 

 Var. y. microstachys, Hook./.? 



Culms pale with dark nodes, L, 15" by -4", glaucous beneath, tip filiform, 

 f anicle rather strict with very long slender erect branches with numerous sheaths 

 bearing several peduncles, some again branched. Spatheole -4", spikes divaricate 

 and rettexed 'o or less with about 3-4 prs. spkts. only. Joints and pedicel 'OS-Og" 

 cdia up to -06" long. Sess. spkt. -U-'IS", gl. i 2-keeled. oblong lane, with 2 very 

 distinct green nerves between the keels, dorsally flat, keels slightly excurrent. 

 narrowly winged or margined above the middle aiid scabious ; ii with scaberulous 

 keel, inflexed margins softly ciliate ; iv -08" 2-fid wath filiform segments awn -25". 



Champaran, common ! This may be A. iiardiig proper of F.B.I. , but the spikes 

 and spikelets are very small. It dilTers from var. microstachys in the denser 

 decompound panicles and prominent nervation of gl. i. 



4. C. microtheca, Hool; f. Var. sameshwarensis. 



Tall 4-5 ft., nodes dark-coloured or not. Upper leaves 15" by -2" 

 A\ith scabrellous margins and marginal nerves and sometimes scabrel- 

 lous above on all nerves, somewhat silky above the scarious •07"-long 

 ligule. Panicle decompound odourless. Spatheoles •4--5" finely 

 acuminate or sub-aristulate, two to four very shortly exserted from 

 a spathe not much exceeding them which has the peduncle bearded 

 on one side near the pale swollen tip and is often subaristate. Spikes 

 very short -3" or less, strongly reflexed on their very short common 

 peduncle which is also ciliate on inner side and under" -5" long, base of 

 spikes long-eiliate, joints and pedicels -OT— 08" long slender gradually 

 wider upwards, toothed (mostly with one large and 2 smaller teeth).
