Along the transition zone between Kashmir and Ladak almost 
any Kashmir plant that will live above 10,000 feet may be found, 
especially in Suru. Most of the plants are alpine mesophytes. 
Only 10 per cent. of these were also found in Rupshu, and they 
are forms like Delphinium Brunonianum, Potentilla bifurca, Leon- 
topodium, Taraxacum, and Aster heterochaeta, which are widespread 
at high altitudes. Most of the plants in my list, that do not seem 
to have been reported before from Ladak, are from this transition 
region and are common Kashmir types. Examples are Podo- 
bhyllum Emodi, Lavatera Kashmiriana, species of Impatiens, Lotus 
corniculatus, and Astragalus frigidus. The same may be said of the 
species from this region which were first collected by Meebold. 
Coming from Kashmir, Meebold was impressed with the 
barren, Tibetan aspects of Suru, but going in the other direction 
later in the summer I was struck by the greater amount of green 
on the hillsides. While there are no forests and few trees, except 
willows, Juniperus and Lonicera glauca, there is much more her- 
baceous vegetation than in the rest of Ladak and everything indi- 
cates more moisture. This increased water supply is no doubt due 
to the presence of the Nun Kun peaks and glaciers. The greater
