These were found on lower heights.
I have seen Rhododendrones in all the colours but very few white ones, They were trees of medium height


One possibility is Rhododendron wightii

One feature of this is that leaves are brownish of greyish on the underside.

Two more Rhododendrons- Perhaps
100_1255.JPG- R. pronum
100_1263.JPG- R. hirsutum
on way to Bumla pass- 11000-12000 ft. Needs confirmation


The pink flowered rhododendron is R.campanulatum and the first one looks like R. anthopogon (note:-flowers should be in yellow color) and if not than check R.lepidotum


Please find attached herewith the identified species. R. wightii & R. campanulatum respectively.
