The Rhododendron now figured was first discovered 
by the Abbé David about the year 1870 in woods near 
Moupine in Szechuan and was described by the late Mr. 
Franchet in 1886 as R. lutescens. It has been met with 
again in the same province by Mr. E. H. Wilson on 
various occasions when collecting on behalf of Messrs. 
J. Veitch and Sons and for the Arnold Arboretum. His 
notes speak of it as very common in thickets and in the 
Aprit-J UNE, 1920,
