1 am indebted to Dr Greville for the figure here giverf, 
and to Dr Graham for the description of this superb plant, 
both of which were taken from a plant that blossomed in the 
greenhouse of Mr Cunningham at Edinburgh, in June 1825. 
The plant, as is well known, is a native of Nepaul, where 
it was found by Dr Hamilton and Dr Wallich about 
Narainhetty. General Hardwicke, I believe, first detected 
it in the mountainous tract called the Sewalic chain, which se- 
parates the plains of Hindostan, between the 75° and 85° of E. 
longitude, from the Himalah mountains. There, among fo- 
rests of oak, it rises with a stem 20 feet or more in height, and 
from 16 to 24 inches in diameter. About London, we know 
it has been cultivated in the open air, and we are not without 
hopes that it may be made to flower while treated as a hardy 
plant. 
Besides the vivid colour of the blossoms of this plant, the 
leaves present a fine appearance, from their size, and the sin- 
gular silvery tomentum or down which covers their whole un- 
der surface, with the exception of the midrib. 
I possess numerous native specimens of this plant, through 
the liberality of the Honourable the East India Company, to- 
gether with some other species of the same genus, and from 
the same country. Amongst them is one very nearly allied to 
this, which is marked by Dr Wallich as the Rhod. campanu- 
latum of Mr Don. This has shorter and much broader leaves, 
clothed on their under side with a dense ferruginous tomentum. 
The flowers appear to be longer than in the Rh. arborewniy 
and either of a rose-colour or white when living. 
The R. arboreum sometimes varies in its native country 
with white flowers, and the silvery hue of the lower surface of 
the foliage is far less distinct in some individuals than in 
others.
