Handbook, to restore the /. hipartita^ of Wight and Arnott, which in 
that work is (following ThwaiteSj referred as a variety to the Malabar 
/. cuspidata, W. & A. and in the Flora of British India to 1 . Jlaccida, 
Am. Also I have, following Beddome, referred /. Hookeriana 
Am., to the Malabar /. grandis,^ Heyne. 
All the Ceylon Balsams, 21 in number, like those of Malabar and of 
the Malayan Peninsula, belong to the division of the genus with short 
capsules turgid in the middle ; fifteen are endemic, but for the most 
part allied to Malabar congeners ; to which latter region the remain- 
ing six belong, namely, I. acaulis^ oppositifolia, Bahamina, Henslo* 
viana, flaccid a and grandis, of which /. oppositifolia- is also found in 
Burma, and /. Bahamina is widely distributed over various warm 
parts of India and Eastern Asia. Except /. acaulis^ no Ceylon 
species presents any abnormal character, such as the 4 sepals of 
various Himalayan and Burman species, or the filiform development 
of the dorsal auricle of the wings descending into the spur of the lip, 
which occurs in species of the E, and W. Himalayan regions, Burma 
and Malabar,
