106 BALFOUR—NEW SPECIES OF RHODODENDRON. 
species of the series. The conspicuous style-character is shared 
by Rh. pogonostylum, Balf. f. et W. W. Sm. alone in the series, 
nd in that species perhaps Rh. facetwm finds its nearest ally. 
The corolla hairy on the outside in Rh. pogonostylum and the 
glands beneath the tomentum on the ovary separate it readily. 
. facetum carries farther westwards into Burma the dis- 
tribution of a Irroratum series. Kh. tanastylum, Balf. f. et 
Ward found at Hpimaw is the only species outside Yunnan 
hitherto assigned to the series, which occupies a much wider 
geographical area than I knew of when I read an account of 
the series before the Botanical Society of Edinburgh in 1917. 
I have since that date found amongst collections made by Mr. 
R. E. Cooper in Bhutan specimens under Nos. 4086, 4160, 
4978 of Rh. Kendrickii, Nutt. corresponding in all respects with 
Mr. Griffith’s Bhutan specimens of the species under No. 2235. 
Analysis of the new Bhutan material of this little-known species 
suggests that Rh. Kendrickit is an Eastern Himalayan repre- 
sentative of the West Chinese forms assembled in the series 
Irroratum. Nuttall,* and following him C. B. Clarke,f thought 
the affinity of Rh. Kendrickit was with Rh. arboreum, Sm., from 
which it differed, as Clarke says, “‘ by the very narrow capsule.” 
e general outward resemblance of dried specimens of Rh. 
Kendrickit o those of Rh. arboreum naturally tempts to the
