BY 
NELLIE CARTER, D.Sc. 
The Algae recorded in this paper were collected by Mr. 1. H. Burkill at 
various times between 1906 and 1912 in India. A considerable amount: of 
work has already been dorie on the algal flora of the Indian region, and @ 
complete list of the literature relating to it will be found in W- & G.S. West, 
Freshwater Algae from Burma, etc., 1907, 80 that it is unnecessary +0 refer 
to these papers here. 
_ The majority of the collections were made near the North-Eastern frontier, 
in North Cachar, the Assam plains, and in the Sikkim and. Abor Himalayas. 
A number also came from the North-West Himalayas near Suma, or from 
Nepal. The remaining samples were collected in the Plain of the Ganges, 
shag Satpura Hills in the Central Provinces, from Akyab, or in the Dawna 
S$. 
Most of the samples were taken at fairly high altitudes, varymse proee 
2,000 ft.—10,000 ft., whilst a few of the collections 
—700 ft. The latter, as would be expected proved 
former ; in fact nearly half the species recorded here 
taken from a ditch in a rice field near Sadiya at 
Were recognised. These included many of the 
of the Indo-Malayan type (see W. & G. 8. West.
