258 ILLUSTRATIONS OF THE BOTANY OF [Ericacee. 
tains of Nepal, and referred by Mr. Don with the Japan species to his new genus, Pieris. 
The last is also found in the mountains of Sirmore and Gurhwal, with Dr.Govan’s variety if 
not distinct species, A.cordata ; both are common at elevations of from 5,000 to 8,000 feet 
along the Mussooree Range from Dhunoultee to Budraj. The fifth species, A. fastigiata, 
closely resembling A. hypnoides, lycopodioides, and tetragona, found in northern Europe 
and America, and along Siberia to Kamschatka, has been formed with these into a new 
genus (Cassiope) by Mr. Don. Dr. Wallich obtained it from Buddrinath and Gossainthan. 
I have found it on Choor and Kedarkanta at elevations of from 9,000 to 12,000 feet, 
and have obtained it from Kunawur. It may be seen in flower from April and May to 
June, according to the elevation, and is called seeroo on the Choor mountain. It has 
been figured by Dr.Wallich, Pl. As. Rar. t. 284, and repeated in this work, t. 63, 
on account of the interest it has excited in consequence of being supposed to be the 
only heath found in Asia. This was in consequence of travellers, especially Mr. Fraser, 
having mentioned that they had met with the heath in the mountains. Mr. Saunders 
(Turner’s Emb. to Tesshooloombo), probably alludes to the same ‘plant. Dr. Govan 
appropriately calls it the heath-like Andromeda. 
The species of Rhododendron found in the most southern latitude is R. nobile, Wall. 
found on Adam’s Peak, in the Island of Ceylon, and on the Neelgherry mountains ; 
the specimens from Kemaon belong rather to R. barbatum and campanulatum. This 
species is nearly allied to the well-known Boorans or R. arboreum, which is found at 
the lowest elevations and in the most southern latitudes of the Himalaya, that is, from ~ 
Chirraponjee and Nepal to the Sutlej, or from 25° to 32° of N. latitude, at elevations in 
Gurhwal of from 5,000 to 8,000 feet. In the ascent to Mussooree, it is first met with 
above Jurreepanee, and presents a broad belt of large trees, which, when in flower in 
March and April, with every branchlet terminated with a bunch of large crimson 
flowers, forms one of the most magnificent objects in nature. The cold it. experiences 
at the highest elevations is necessarily considerable in winter, but the rise and fall of 
temperature being so gradual, it is better able to bear a greater degree of severity than 
the changes of an English climate. But even this, by careful management, it may be 
made to withstand; for I am informed by Mr. Anderson, of Chelsea, that some trees 
which were planted more than ten years since in the open air, have flowered this season 
in great luxuriance at the Earl of Winchester’s, at Ashridge, in Herefordshire. The only 
precautions taken were to place the plants, when two years old, in a sheltered situation, 
and to cover the ground in their neighbourhood with a thick layer of fern leaves in 
winter. There is a-white variety of this species in Nepal, Kemaon, and Sirmore, but 
itis not common. It has been figured by Dr. Wallich, from Sheopore, at an elevation 
of 10,000 feet, where the rose-coloured variety is also found, Pl. As. Rar. t. 128, and 
by Dr. Lindley, Bot. Reg. N. 1684, from Mr. Well’s Conservatory at Redleaf. R. 
cinnamomeum, is nearly allied to R. arboreum: R. formosum, Wall., Pl. As. Rar t. 207, 
is distinguished by its lepidote leaves and few flowers, and R. barbatum by the setze 
surrounding the petioles and upper part of branches.
