the awned ; IV the hyaline base of the awn. Hackel classifies the form of this protean 

 plant under 6 subspecies and 12 varieties. Of these the Indian (exclusive of inter- 

 mediates) may be grouped as follows. They do not affect definite areas, and some of 

 them may be different states of one variety. 



Subsp. genuina, Hack. 1. c. 672 ; panicle decompound, branches branchlets and 

 peduncle of spike villous with rusty hairs, proper sheaths 1 1 in., spikelets | in. 

 or more dorsally hirsute with rusty-brown hairs, bisexual spikelets 1-3 in each 

 raceme in. awned or not. A. gigantea, Cav. I. c. A. vulpina, Anderss. in Nov.

Subsp. arundinacca (including subsp. intermedia), Hack. I.e. 674; panicle 

 compound dense or lax, branches and branchlets glabrous, proper spathes l-2 in. 

 ciliate, invol. spikelets ^-f in. dorsally hirsute with golden or rusty hairs, bisexual 

 spikelets 1 rarely 2 in each spike about -j in long, awn 1 4 in. A. arundinacea,

 from arundinacea in the less hirsute male spikelet and in the awn reduced to a 

 bristle.

 glabrous or scaberulous, proper spathes 1-1 ^ n -> spikes erect or divaricate, invol.

Var. longispatha, Hack. 1. c. 677 ; leaves glaucous beneath smooth except the 

 scabrid margins, stems and sheaths quite glabrous, panicle broad compressed, 

 branches scaberulous, pedice)led spikelets nearly smooth except the scabrid keels, 

 involucr. spikelets about f in. ^-Terai of the Himalaya, Kuntze. I have seen no 

 authentic specimen. 



DOUBTFUL SPECIES. 



ANTHISTIRIA sp. ? an imperfect specimen from Chota Nagpur, Dr. Wood (Herb* 

 Calcutt.) with the invol. gls. of J.. gigantea, var. villosa, -but with very broad leaves- 

 deeply cordate and amplexicaul at the base. 



55. ISEILEMA, Hack. 



Differs from Anthistiria in each spike being jointed below the iuvolucral 

 spikelets on the top of its peduncle, and falling away from it as a whole 

 after flowering ; whereas in Anthistiria the involucrant spikelets are 

 persistent and the rest of the spike deciduous. In the former case, as 

 Hackel observes, the dispersal of the species is by the wind, in the latter
