130 BALFOUR—NEW SPECIES OF RHODODENDRON, 
found with fruit below, but a few in flower at summit ; former 
collected. Large balls of flowers yellow white. Young leaves 
erect white woolly below with large red bracts and scales forming 
a curious feature of vegetation at thisseason. Watt. No. 6892. 
May 18, 1882. 
Manipur. Japvo, Naga Hills. Alt. 8000-9500 ft. Re- 
gathered by my friend Dr. Conry, who reports that it was quite 
out of flower in July, also RA. Elivottii—just three specimens in 
flower. Leaves densely and softly tomentose or lanate. This 
seems to me a remarkable form the leaves being much more 
elliptic than in the Sikkim plant. Named in honour of the 
Deputy Commissioner, Naga Hills, who accompanied me on my 
first trip to the Naga Hills. Watt. No. 7334. July 
22, 1882. [Mr. M‘Cabe was subsequently killed in the great 
earthquake.—G. W., I915.] 
In Sir George Watt’s Herbarium are four sheets of specimens 
of this Rhododendron collected by him in Manipur, and which 
he regarded as a variety of Rh. Falconert, Hook. f. and named 
var. Macabeanum. It differs from Rh. Falconer1, Hook. f. ina 
degree too great to allow of our looking upon it as a form of 
that species. Prominent differences are :—The leaves want 
the cordate base, the indumentum is composed of branching 
stalked hairs not of cyathiform scales, the pedicels and ovary 
are tomentose and altogether deficient in glands. The plant 
is much more closely related to Rh. grande, Wight (the relation- 
ship was recognised by Sir George Watt: see his interesting and 
prescient comments quoted on pp. 131-32), but is not identical 
with that species, differing in the broader leaves, in their ulti- 
mately lanate indumentum, in the eglandular tomentose short 
pedicels and ovary. As a distinct species of the Grande series 
of Rhododendrons Rh. Macabeanum, Watt is of special interest 
as a connecting link between the Sikkim and Bhutan Rh. grande, 
Hook. f. and the Eastern Burmese and Yunnan Rh. sinogrande, 
Balf. f. et W. W. Sm. To Rh. sinogrande, Balf. f. et W. W. Sm. 
its resemblance is greater than to Rh. grande, Wight, but the 
smaller leaves, the longer hairs of the indumentum ultimately 
making the under surface of the leaves woolly, and the shortly 
stalked flowers making a compact umbel are easily observed 
diagnostic marks. 
Sir George tells me that in the early eighties of last century 
he sent home in manuscript descriptions of this and other species 
along with his Manipur collections which were made use of to 
some extent by Mr. C. B. Clarke for his paper ‘‘ On the Plants 
of Kohima and Manipur,” published in the Journal of the 
Linnean Society, xxv (1890). The novelties of Dr. Watt’s col- 
lecting which had not been collected also by Mr. Clarke were not
