This species has much larger flowers than the preceding, 
though the difference is not well indicated in Wight’s figures ; 
and the hairs of the disc are also much less distinct. The 
flowers are white, with a little light yellow in the throat.

This has much larger flowers than the preceding, as much 
as 3+ inches long. The colour is pure white. From sketches 
of the flowers and fruit sent by Sir John Kirk the bracts would 
appear to be deciduous before the capsules are mature. The 
material at hand is very impertect. 
The following may belong to this species :—A sketch from
