SUBSUBAREAS OF BRITISH INDIA. 5 
(3) The eastern boundary is 76? 30' Long. E., as far south as 
Mysore town, whence the boundary is a line drawn from 
Mysore to Tinnevelly. [I have, generally, tabulated plants 
labelled * Pulneys" in (3). Dindigal is of course in (5). 
The line from Mysore to Tinnevelly is artificial and not very 
satisfactory ; it remains for some one to discover a better. 
(5) The north boundary is the base of the hills which run east 
and west nearly parallel with the Ganges from Gwalior to 
Rajmahl at the great bend of the Ganges. Thus subsub- 
areas (3) and (5) together include the Gondwana region of 
geologists (except the Aravalli Mts., from which I have 
hardly a plant). Mt. Aboo, not being in Gujarat, is 
tabulated in subsubarea (2). 
(6) The Gangetic plain is a Hooker-and-Thomson area; it 
extends from Saharunpore to the sea, including the plain 
of Orissa. The Terai of Nepal and Sikkim is here supposed 
part of the East Himalaya (7). 
(8) Assam is understood to be the political province, as bounded 
by the present “inner line” of the 16-mile-to-the-inch 
administration map; but excluding such portion as drains 
into the Irawaddi: ©. e. Muneypore is in subsubarea (9). 
It is true that the administrative line which separates 
Goalpara from North Bengal is arbitrary; it does not 
appear possible to separate the Bruhmapootra Valley (ot 
Assam) from North Bengal by any line that is not 
arbitrary. 
(9) This arca includes all Burma that is not in Pegu nor iv 
Assam; and includes Muney poor as being a side valley of 
the Irawaddi. 
(10) The boundary-liue between this and Ava is the boundary - 
line between Pegu and Burma in 1870 (and for some time 
before, aud after); so that it coincides with the north 
boundary-line of Kurz's ‘Forest Flora of Deen / The 
southern boundary, in the latitude of Junkceylan, is 
drawn to keep our subsubarea (11) identic with the “ Malay 
Peninsula" of Sir G. King.
