The neat little Rhododendron which forms the subject 
of our illustration is a native of the moorland tracts and 
rocky slopes characteristic of the loftier passes leading 
across the Eastern Himalaya into Tibet, within a few miles 
of the summits of which it reaches its uppermost limit. 
Here the brilliant red-purple flowers render the species a 
charming object, and after hot sunshine the air is filled with 
the heavy aroma due to a copious resinous secretion which 
testifies to the comparatively dry climate it enjoys. In 
its late flowering, which takes place in June and July, and 
in its early fruiting, which occurs in October, &. setosum 
bears witness to the brief summer of the elevated regions 
it affects. The Bhoteas of Sikkim and of Tibet, who 
know the plant as “Tsallu,” regard it and £&. anthopogon,
