full of Ranunculus aquatilis and Zannichellia palustris, also 
typical of similar situations in West Tibet.” 
In the Introduction to Hooker and Thomson’s ‘ Flora Indica,’ 
from which the preceding paragraph was extracted, ‘‘ Western 
Tibet,” including Little Tibet and Baltistan, is divided into eight 
Provinces, namely :— 
1. Guge, the Tibetan course of the Sutle). 
2. Piti and Parang, the basins of the rivers of those names, 
tributaries of the Sutlej. 
. Zanskar, the basin of the Zanskar river. 
- Drags, the basin of the Dras river. 
. Nari, the upper course of the Indus. 
. Ladak, the middle Tibetan course of the Indus. 
. Balti, the lower Tibetan course of the Indus. 
. Nubra, the upper basins of the Nubra and Shayuk rivers, 
tributaries of the Indus. 
These Provinces comprise the country botanized by Thomson, 
Strachey and Winterbottom, and others ; but only Gugé and Nari 
come within our limits. 
Respecting the boundary between India and Tibet, in relation 
to botanical regions, the authors express the opinion that it 
should begin where the dry region begins, and this is practically 
the boundary adopted in this paper.

Having made use of many of their data, it may be worth while 
to indicate briefly their route in the North-west Himalaya and 
‘Tibet. They traversed the country in many directions between 
70° and 80° and between 80° and 37°—that is to say, the valleys 
ofthe middle Sutlej and Indus and the upper Ravie, Chenab, and 
Jelam rivers. They crossed into Tibet by the Milam route, and. 
reached as far north as Gartok; and they crossed the Karakorum 
and Kuen Luen chains intwo places. Bushia, in the direction of 
Khotan, was their furthest to the north-east; but they reached 
Yarkand and Kashgar in the north-west. From the south they 
crossed the Pass of Skardo and made the southern ascent of the 
Karakorum range.
