or rotate-campanulate corollas, and some of them very 
deciduous perulz to the separate flower-buds.” &. Vaseyt 
‘is one of that group, and it thus adds another to the now 
very numerous cases of remarkable relationship between 
the Chino-Japanese and the Alleghanian floras.” It is 
closely allied to R. Albrechtit, Maxim., and perhaps nearer 
still to R. rhombicum, Miq. (t. 6972), and BR. dilatatum, 
Mig. (t. 7681) ; all Japanese species. 
Rk. Vaseyi was first discovered by Mr. G. R. Vasey in 
1878 on Balsam Mountain, Jackson County, North Caro- 
lina. It was afterwards found on Grandfather Mountain, 
Caldwell County, in the same State, and in Cashier’s 
Valley, South Carolina. Mr. S. T. Kelsey informs us 
that on Grandfather Mountain it was growing everywhere 
in clumps and patches on the southern and south-eastern 
slopes at 4,500 to 5,500 ft. elevation, but most abundantly 
and vigorously in moist situations. It is associated with 
Rk. maeimum, EF. catawbiense, and Kalmia latifolia. 
Professor Sargent mentions that Mr. Faxon, the author 
of the figure in the Garden and Forest, noticed that the 
upper or posterior lobe of the corolla is exterior in the 
expanded flower, a peculiarity not detected in any other 
Rhododendron. The same lobe is innermost in estivation. 
The Kew plants which furnished the material for the 
accompanying plate were raised from seed received from 
the Arnold Arboretum in 1891. They are perfectly hardy, 
and flower annually early in May. 
Descr.—A shrub attaining a height of eighteen feet; 
branches slender, at first shortly pubescent, afterwards

long, recurved after flowering, covered, as well as the 
small truncate calyx, with stalked glands. Corolla bright
