Impatiens Hawkeri is one of the only two species of 
Balsamineae hitherto discovered in New Guinea, the other 
being the closely allied J. Herzogit, K. Schum. (? = J. 
cordipetala, Zipp.). These are the most easterly members 
of the family in Asia, from which continent and its islands 
about 500 species are preserved in the principal European 
Herbaria. The most remarkable feature of these Asiatic 
species, Sir Joseph Hooker points out, is the very restricted 
geographical area to which they are confined. There are 
five such areas, each of great extent: the Himalayan; the 
Burmese, including Assam; the Western Indian Peninsular, 
including Ceylon; the Chinese; the Malayan, from Sumatra, 
- Java and Borneo eastward to New Guinea and the Philip- 
pines. No two of these areas contain more than half-a-
