THE VEGETATION! OF THE DISTRICTS OF 
631 . Oryza Linn. 
Oryza sativa Linn.; H. S. 71 1 ; B. P. ii. 1184. 
v. Dhan. Rice. 
Cultivated everywhere in several forms, some without awns, others 
with awns of varying length : native of various parts of India. 
var. * fatua ; B. P. ii. 1184. 
v. Dhan. Wild Rice. 
Occasionally met with in the Sundribuns, but it is possible that 
the Sundribuns wild stock is only feral after escape and not truly 
wild. It is apparently always long-awned. 
* Oryza coarctata Roxb, ; B. P. ii. 1184. 
v. Dhani ) harakata . 
Western Sundribuns, common. 
633 . Leersi'a Sw. 
* Leersia hexandra Sw. ; B. P. ii. 1185. H ygrorhiza ciliata H. S. 
710. 
Floating on ponds and jhils, everywhere. 
633 . llygrorkiza Nees. 
* Iffygrorhiza aristata Nees; B. P. ii. 1185. Potamochloa Retzii 
H. S. 7 1 1 . 
v. Jangli dal. 
Floating on ponds and jhils, general. 
634 . Tragus Haller. 
* Tragus racemosus Scop. ; B. P. ii. 1186. 
Goghat, Western Hughli, in dry fields. 
635 . Perotis Ait. 
* Perotis latifolia Ait. ; H. S. 710; B. P. ii. 1 f 85. 
Dry fields, west of river Hughli, occasional. 
636 , Zoysia Willd. 
* Zoysia puugeus Willd. ; H. S. 709 ; B. P. ii. 1186. 
Western Sundribuns, common, also reported by Voigt from Seram- 
pore. The latter record is not altogether impossible, but it is doubt- 
ful if the conditions in the neighbourhood favour the existence of 
the grass there now. It is particularly abundant in half-cultivated 
ground about Canning Town.
