staminodia tria, posticum lateralibus minus. Discus annularis, crenatus, 
vix 1-5 mm. altus. Ovarium elongatum, ut stylus glanduloso-pubescens. 
There are no authentically named specimens of Didymo- 
carpus cyanea in the Kew Herbarium, but the plant figured 
agrees so well with the original description, except as 
regards the scapes, which are described as 2-flowered, that 
there is little doubt as to its belonging to that species. 
D. cyanea was collected at Kasum, in the Siamese part of 
the Malay Peninsula, by Mr. C. Curtis, Superintendent of 
the Botanic Gardens, Penang. . 
Ridley remarks that the number of Didymocarpi in the 
Siamese-Malayan region seems endless, every district sup- 
plying one or more new kinds; and the same holds good 
for many other genera of Gesneraceae in different parts of 
the world, as for example the Tropical American genus 
Columnea, of which more than twenty species have been 
described from Costa Rica alone.
