East Himalayan species and 8 more than for the 57 Western 
Peninsular. It cannot well be doubled that ampler materials will 
increase or reduce or abolish some of these. 
Of the 52 Purmese species, 39 are endemic. Of the remainder 
one, I, Balsamina, is not confined to any of the Indian regions : /. 
hracteata^ pulchra^ latifiora^ trilohata^ tripetala^ arguta^ Jurpia, 
radiata^ drepanophora and racemosa are Himalayan, of which L 
arguta is also Chinese; I. oppositifolia and /. chinensis are Western 
Peninsular. None are Malayan Peninsular, but one, /. Parishii which 
has no Burmese ally, is nearly related, both in geographical position 
and character, to one of that region. A small group § 10, and a few 
species of other groups inhabit the sea level in Arracan, Lower Burma 
and Tenasserim. They are inconspicuous and small flowered, and 
have been for the most part very carelessly collected. 
Hitherto the only link that has been discovered between the 
Impatxens of Eastern Burma and those of the coterminous provinces 
of Western China, is the presence in both of /. arguta^ and what is 
more surprising is that the Chinese species belong for the most 
part to sections of the genus of which there are few or no Indian 
representatives. 
Key to the sections.
