N.E. Upper Burma. Chawchi Pass, etc. Alt. 10,500 ft. A 
smaller tree than the last [presumably 1551] in full blossom amid 
the snow. Flowers very copious but of a virulent blue-magenta 
like Rh. fastuosum fl. pl. Though much like this some of its 
tones are less displeasing than others. Nos. 1549, 1551, 1552 
make up the spring flowering Rhododendron forest at 10,500 ft. 
F, 4552 is particularly abundant and copious just now among the 
snow at 10,500 ft. Farrer No. 15528. May 15, 1920. 
Also in miles of colour in the open on the Maguchi Pass. June 
Specimens of this very distinct plant were found in the cover 
along with those of Rh. chawchiense under No. 1552. There is 
no means by which one can say to which set of specimens the 
ticket refers. I have numbered this specimen 15528 and those of 
Rh. chawchiense 15528.
