stamens. In full bloom. Calyx green dusted with scaly meal. 
One of the prettiest dwarf Rhododendrons met with colouring the © 
bare rocks. Leaves aromatic, flowers slightly fragrant. King- 
don Ward No. 3302. 2.7.10. 
A good many plants still in bloom. This with Nos. 3290, 
3301 [Rh. aperantum], 3365, 3610 and dwarf salix forms the bulk 
of the carpet covering the granite rocks of Imaw. Kingdon Ward.

Kingdon Ward. 25.7.19.”’ 
This plant found by Ward is in vegetative characters very 
like the Burmese Rh. charitopes, Balf. £. et Farrer discovered by 
Farrer. Both of them belong to the phylum of Rh. brachyan- 
thum, Franch. within the Campylogynum Series. Looking at 
leaves and stems in the dried specimens I have not found diag- 
nostic characters. But when we come to the flower there is 
abundant specific difference within the bounds of the phylum. 
I will only indicate here that Rh. charitostreptum has unspotted 
yellow flowers, the corolla short subrotate lepidote outside villous 
in the throat and with short entire lobes in contrast with the 
spotted white suffused pink flowers (apple blossom) of Rh. chari- 
topes in which the corolla is campaniform nearly half again as 
long glabrous outside and with broad two-lobed segments. ‘There 
are other points of difference. The two species are quite dis- 
tinct, but certainly the vegetative resemblance is remarkable.
