The genus Hoya attains its maximum in transgangetic 
India, and there are still many beautiful species to be im- 
ported, especially from Assam, Burma, and the Malay 
Peninsula and Islands. Westward the genus rapidly 
diminishes in number of species, and is confined to the 
hotter and damper valleys of the Himalaya. In the most 
recent examination of the Indian Hoyas (Flora of British 
India, ined.) there are described seventeen species from the 
country extending from Burma to Malacca ; thirteen inhabit 
the Khasia Mountains and Assam ; ten are found in Sikkim ; 
four of the latter in Nepal, and only two of these enter 
Kumaon, which is the western as well as northern limit of 
the genus; five are known in the mountains of the Deccan 
Peninsula, and only two in Ceylon. By far the most 
gorgeous species are natives of Borneo and the Moluccas, 
from whence the allies and rivals of H. imperialis, namely 
H. grandiflora, Blume, H. Ariadne, Dene., A, lutea, Dene., 
are to be obtained. oe 
H. linearis was founded by Wight on Wallich’s Nepal 
APRIL lst, 1883.
