Description : Cke. I.e. except for the number and; description ©f the glumes, 

 this part of the diagnosis must read like this:. Glumes. 4: Lower invoSucral 

 glume more or less dorsally hairy, with ciliolate margins ; upper involucral 

 glume with a densely ciliate keel ; lower floral glume obovate-oblong, 

 hyaline, nerveless ; upper floral glume 2-lobed, with a geniculate awn about 

 12 mm. long from the sinus r column of awn 4 mm. long, spirally ciliate,. brown, 

 the upper part of the awn yellow, longer than the column.

6. Ischjemum, Linn. (Cke. ii, 957) 



Species about 50. — All belonging to the Old World, except 3 found fn 

 tropical America. 



Cooke, 1. c. describes 12 species. Of these Isehtemum angustif&Hum has 

 to go under Pollinidium and 1 'serhcemum laxitm, sulcatum and sp-athiflorum 

 under Schima. Instead 3 species new to the Presidency will be added to the 

 genus Isck&mum, viz;. /. impressum r Hack., /. conjugatum t Roxb. and 

 /. timorense, Kth. 

 In Ischcemwm the racemes are geminate or digitate.
