29. Dendbocalamus.] 97. GRAMINEM. [30. Cephalostachyum. 



A very strong useful bamboo, but the Singbhum culms were not 

 favourably reported on for lance shafts by Messrs. Manton & Co. to whom 

 some specimens were sent by Mr. E. R. Stevens. The new shoots are 

 eaten. 



Var. sericeus, Munro (Sp.) only grows on Parasnath. It is distin- 

 guished by having softly silky spikelets and obtuse anthers, the anthers 

 of the type being apiculate. 



30. Ceplialostacliyum, Munro. 

 1. C. pergracile, Munro. 



A handsome csespitose bamboo with culms about 2" diam. 

 Stem sheaths light brown deciduous 5*6", young with felted 

 deciduous shining black hairs without, blade triangular 

 acuminate only 2", felted within towards the base, with densely 

 fimbriate setose sometimes reflexed auricles, ligule hardly any. 

 L. 8-10" by 1-1 1" with twisted tip and soabrid margins. 



Sides of valleys in Singbhum but rare (Luia in the Kolhan, Kiringka 

 Lor in Porahat). 



Wall of culms very thin. L.-sheaths with closely ciliate margins and 

 with long set® or bristles above when young. Pellucid nervules usually 

 joining two tertiary nerves. Inflorescence (fide Gamble) a large panic 1 e 

 with verticels of long drooping filif orm npikes, bearing distant broad heads 

 of spikelets supported by small chaffy sheathing bracts ; the rachis very 

 Blender, wiry, thickened abov*, and 1^-2" between the cluster*. Fafe 

 long, apex deeply bifidlymucronate. 



The green culms split and crack in drying in Chota Nagpur, but 

 Gamble says they are used for building in Burma. 



* Note. — The " nerves " refer to the stronger nerves each side of 

 the mid-rib.
