THE VEGETATION OF THE DISTRICTS OF 
In ditches in the vicinity of Calcutta chiefly. 
The form of this grass with variagated leaves, rather a favourite 
plant in gardens about Calcutta, is an introduction from Europe and is 
a form of the European variety of this species. Voigt gives two Indian 
forms as occurring in our area ; the first is the Gaba nal ( Arundo 
hengalensis ) which is the Bengal form of the European Arundo Donax ; 
the second which Voigt terms Unal is the form of Arundo Donax 
characteristic of the Circar Mountains (Eastern Ghats), Roxburgh's A. 
bijaria . It is doubtful if the latter be really indigenous in our area. 
The difference between the two grasses is chiefly in habit, the in- 
florescence in A. hengalensis being more lax, in A . hi f aria more 
compact ; the distinction between the two is much like the distinction 
between the Teng [S accharum arundinaceum) and the Shur ( Saccha m 
rum Sara), but is less pronounced.

Goghat, Western Hughli district, in poor dry soil. 
Eragrostis aspera Nees, Poa paniculata H. S. 716. 
Reported from Serampore by Voigt, but the record is most im* 
probable, as the species is confined, so far as is known, to Southern 
and Western India. Probably some other species is intended but 
there is no clue as to which.
