BALFOUR—NEW SPECIES OF RHODODENDRON. 123 
Maddent is one of the most abundant bushes in the higher 
Manipur Hills and in our Naga Hill district. It may be said to 
make its appearance in the eastern corner of Sikkim and to 
be spread eastward to the higher Naga Hills and North-Eastern 
Manipur. 
“It was gathered in the Duphla Hills by Mr. Lister (a 
collector sent out from the Botanic Gardens, Calcutta, in 1875), 
very imperfect specimens being received. Griffith’s Bhotan 
specimens No. 3507 most probably belong to this species, as 
also those gathered by Simmons in 1855. Through the want 
of interest taken in botanical science in India it is to be de- 
plored that the history and distribution of so exceedingly in- 
teresting a plant should have practically remained unknown 
from the date of its original discovery in 1849 to the present 
day. 
ie It is very probable that my plants are nearer to the plant 
introduced by Booth from Bhotan and figured by Hooker in 
Bot. Mag. t. 5002—Rh. calophyllum. Not having seen the 
flowers of that plant I rely upon foliage entirely, and as far as 
one can judge from such material it might be better to regard 
the Manipur plant as calophyllum. It seems likely, however, 
that this species may be regarded as being a Bhotan form of 
Maddeni and not a distinct species, and for both these reasons 
I have considered it advisable to refer my plants to the more 
typical and best known form.” 
Note added 1915.—‘‘ I sent to Kew seeds of all the rhododen- 
drons I was able to collect. One grown under the name Rh. 
Elliottii, Watt proved to be Rh. Maddeni, and I was assumed to 
have made a mistake. But here I describe Rh. Madden as a 
separate species from Rh. Elliottii. I had never any doubt, and 
so the labels on the seeds must have got changed either by me 
or the staff at Kew. The Kew plant has been figured and de- 
scribed as Rh. Maddent, var. obtusifolium (Bot. tae oe: 
With reference to Sir George Watt’s note :—Rh. Elliottat is 
a plant very different from Rh. M addent, Hook. f., and its char- 
acters have been presented recently by, Lace and Smith in Notes 
from the Royal Botanic Garden, Edinburgh, viii (1914), 214. 
The Rh. Maddeni, var. obtusifolium, Hutchinson of the Bot. 
Mag. t. 8212 does not appeal to me as a form of Rh. Maddeni, 
Hook. f., and I note that Mr. Watson, writing of its cultivation, 
says: “It differs in habit and several other characters from 
the Himalayan Rh. Maddeni as represented in gardens.” As 
described it differs from Rh. Maddeni, Hook. f. in the two dis- 
tinctive characters to which I have referred on a previous page
