at or below the middle. Lodicules minute or 0. Stamens 2, filaments 

 short, anthers small. Styles distinct, stigmas short. Grain linear, 

 laterally compressed, free.

1. D. ornithopoda, Trln. 



A very slender annual 3-15" high with many leafy stems from the 

 root. Leaves erect linear •5-2", rarely 3", hairy or ciliate and sheaths 

 with long spreading hairs (or, var. tenera) glabrous. Spikes 2, rarely 

 3, •5-1-5" long with slender very flexuous rhachis about -02" broad 

 with scaberulous margins. Spikelets about twice as long as joints of 

 rhachis, •05-^l", alternate sessile or subsessile -1" long with a pencil 

 of hairs at their base. Gl. i linear, a little shorter than the spkt. ; 

 ii linear, coriaceous Avith hyaline margins, as long as spkt., ^02" wide 

 when folded (they are strongly conduplicate), a few fine hairs on keel 

 near apex ; iv about |ths ii, very narroAv hyaline Avith terminal awn 

 •25" long. Grain linear -07" long. .

Tbe flowers of the Parasnath specimen are exceedingly small ('Oi '). and Ilackel 

 called it minutijlora. The spkts. of var. tenera are -08" long. 



2. D. connivens. Had. 



A much tufted grass with leaves chiefly near the base of the very 

 slender ascending stems, 4-10" high, nodes minutely bearded. Leaves 

 linear with long tubercle-based hairs chiefly on their margins, acu- 

 minate, -5-3" long, not over ^15" broad. Spikes erect parallel, 1-1-5" 

 long, rhachis •OS" Avide. Spkts. -14-- 15" long excluding the -3" long 

 awn, with a minute pencil of hairs at their base. Gl. i slightly shorter 

 than spkt. finely pointed, dorsally ciliate ; ii as long as spkt. acu- 

 minate, ^04" broad, prominently keeled and ciliate, with cilia especially 

 long towards the top ; iv hyaline 2-fid. Grain -1" long linear slightly 

 curved.

 Fr. Oct -Dec. 



Clarke's Banchi specimen is the type of D. connivens. The leaves are hairy. 

 Rhachis and glumes ciliate, Spkts. -12" or a trifle longer. In view of the great 

 variability in size of the spkts. of ornithopoda and that on the Singbhum sheet 

 both species appear represented, it is possible that co>i7iiceiis is only a form of 

 ornithopoda. 



57. POGONATHERUM, Beaur. 



Slender but often tough and Aviry grasses Avith suberect narroAV 

 leaves and very slender peduncles with solitary terminal spikes. 

 Spikelets binate, sessile and pedicelled similar except that the pedi- 

 celled is smaller and gl. iii sometimes absent. Gl. i narrow-oblong, 

 membranous, tip truncate or rounded Avith a tuft of haii's ; ii subequal 

 or longer Avith acute or 2-toothed tip and terminal aAvn ; iii hyaline, 

 paleate, male ; iv narroAV, hyaline, 2-fid, long-aAvned, palea oblong 

 glabrous. Lodicules 0. Stamens 1-2, anthers long. Stigmas 

 narrow. Grain oblong, free.
