139. GRAMINEJE. [60. Pollinia. 



pediceUata) both equally pedicelled, -08" long, rhachis, j)edicels and 

 short obtuse callus of spkts. with long silky hairs, rhachis fragile 

 articulate. Gl. i narrow-elliptic -oblong, shining (in nature, appearing 

 hyaline when boiled), Avith truncate apex but with the two marginal 

 keels shortly produced, dorsally hairy and ciliate ; ii subequal, 

 scarcely keeled, slightly hairy, minutely 2-fid at its apex and with 

 a very fine awn longer than itself, nerveless ; iii obsolete ; iv narrowly 

 oblong 2-fid or 2 -toothed (_^V/e J.D.H.) and awned, or (in our specimens) 

 reduced to the narrow base of the long twisted awn which is about 

 •75" long. Palea lanceolate-oblong hyaline nerveless about •02--03" 

 long. 



Common in open ground and open foi'est. N. Champaran ! Very common on 

 half -bare soils of hard clay associated with Laggera flava, Vicoa, etc.. in all 

 districts of Chota Nagpur!' Santal Parg. ! Probably iii other districts, but not 

 collected. Fl., Fr, Oct.-Dec. Annual. 



All the Chota Nagpur specimens belong to variety pediceUata. 



60. POLLINIA, Trin. 



Annual or perennial often decumbent below. Leaves conspicuously 

 contracted at the base or petioled. Spikelets 2-nate, sessile and pedi- 

 celled or both pedicelled, in fragile (easily disarticulate) subdigitate 

 or fascicled usually very hairy spikes. Glumes 4, i membranous or 

 coriaceous, dorsally deeply channelled or concave, truncate or narrowly 

 truncate or 2 -toothed with margins narrowh^ inflexed throughout 

 their length ; ii as long, usuallj^ laterally compressed, keeled, acute, 

 iii hyaline or 0, ciliate, paleate or not ; Avhen glume sometimes palea 

 as long as glume i, male or neuter ; iv very short, hyaline, entire 

 2-fid or 2-auricled or reduced to the dilated base of the long awn, 

 palea small or 0. Lodicules obliquely truncate. 8t. 3, rarely 2. 

 Stig. as long. Grain free. 



Sfapf in liew Herb, sights up PoU'uiia into Pollinia, Eidalla, and PuUculum. 

 Of our original species P. articulata is refei'red to Pulicnliim, P. argenfea and 

 Cumiuffii are referred to Eidalia and only ciliata remains in Pollinia. 



1. P. ciliata, Trin. 



A straggling branched grass 2-4 ft. high with rather thickened 

 nodes and firm terete polished internodes. Leaves narrow-lanceolate 

 tapering both ends acuminate 1-4" by •2--5". Spikes 3-10, 1-5-2 -5" 

 long ; joints of rhachis rather stout, somewhat triangular in section 

 and slightly thickened upAvards, shorter than the spikclets, bases 

 bearded, laterally ciliate at least in their lower halves. 8pikelets 

 sessile and pedicelled. Sessile -09" long, callus short blunt bearded. 

 Gl. i flattened dorsally and grooved, oblong, margins inflexed keels 

 scabrid-ciliate and tips ciliate ; ii cymbiform acuminate keeled 

 scabrous-ciliate on keel ; iii absent ; iv minute hj^aline with an 

 awn -4" long ; palea oblong hyaline -04".

 Fl., Fr, Oct.-Nov. 



The pedicelled spkt. usually seems shorter than the sessile, but is otherwise 

 similar. The F.B.I, speaks of a palea to iii which I do not find. The anthers are 

 •08" long, ii is often aristulate (sometimes witli the awn longer than itself, 

 F.B.I.) and hispid on the sides ; iv is sometimes 2-toothed.
