14 THE RHODODENDRONS OF SIKKIM-HIMALAYA. 
spongy moss, often bend down and touch the ground: the foliage, moreover, is scanty, dark green, and far from 
graceful ; so that notwithstanding the gorgeous colouring of the blossoms, the trees when out of flower, like the Fuchsias of 
Cape Horn, are the gloomy denizens of a most gloomy region. 22. Campbellia and R. barbatum T observed to fringe a 
little swampy tarn on the summit of the mountain,—a peculiarly chilly-looking, small lake, bordered with Sphagnum, and 
half-choked with Curices and other sedges: the atmosphere was loaded with mist, and the place seems as if it would 
be aguish if it could, but was checked by the cold climate. 2. barbatum had almost passed its flowering season : itis a 
less abundant and smaller tree than the last mentioned, but more beautiful in the brighter green and denser foliage, clean, 
papery, light-coloured bark, the whole forming a more picturesque mass. 
Along the north-east and exposed ridges only, grew the R. Falconeri, in foliage incomparably the finest. It 
throws out one or two trunks, clean and smooth, thirty feet or so high, sparingly branched: the branches terminated 
by the immense leaves, deep green above, edged with yellow, and rusty red-brown below. ‘The flowers are smaller, but 
more numerous in each head than in the two last mentioned (2. Campbellie and R. barbatum). 
The temperature of the earth in which the above species grew, was, in the middle of May, at twenty-seven inches 
below the surface where the roots are chiefly developed, 49°5’ at all hours of the day: that of the air varied from 
50° to 60°. 
In naming the new species before me of this eminently Himalayan genus, I have wished to record the services of 
some of those gentlemen who, besides Mr. Griffith (to whom a species had been already dedicated by Dr. Wight), have most 
deeply studied the vegetable productions of the country: they are Drs. Wallich, Royle, and Falconer. With their names 
that of Dr. Campbell, the Political Resident at Darjeeling, author of various excellent Essays on the Agriculture, Arts, 
Products, and People, &e., of Nepal and Sikkim, is no less appropriately associated ; and in compliment to his amiable 
Lady I designate that Rhododendron which is most characteristic of Darjeeling vegetation; while to the Lady of the 
present Governor-General of India, I have, as a mark of grateful esteem and respect, dedicated the noblest species of the 
whole race. J. D. H.
