216 LACE AND SMITH—INDO-BURMESE RHODODENDRONS. 
Fruit long linear bursting into 6 carpels with calyx forming a 
ring; near R. Griffithianum.” 
Watt 11,463 in Herb. Kew. without note of elevation. 
Collected as far back as 1882, this very distinct species has 
remained undescribed except for a very brief English diagnosis 
by Brandis in his Indian Trees, p. 410. Of the Himalayan 
species it comes nearest to R. Kendrickit, Nutt., and nearer 
to the cultivated form of that species (Bot. Mag. 5129) than to 
the original Bhutan types. In allocating it among the species 
with small or indistinct calyx lobes we are in accordance with 
Brandis ; Watt suggests above an affinity with R. Griffithianum, 
Wight; the calyx is of that intermediate magnitude which 
cannot be described as obsolete, nor on the other hand as dilated. 
There are abundant differences between R. Elhotti, Watt, 
and its nearest ally, R. Kendrickii, Nutt., in the shape, consist- 
ence, and reticulation of the leaves, in the shape of the buds, 
and especially in the ovary.
