-` This species should perhaps include C. affinis, Wall., C. luteo- 
viridis, Clarke, and the Javanese Tripterospermum trinerve, 
Blume. It is extremely variable in the number and size of the 
flowers and the relative length of the calyx-teeth.

The twining habit and axillary flowers are the only characters 
separating Crawfurdia from the polymorphous genus Gentiana. 
Indeed, as Professor Huxley points out (Journ. Linn. Soc. xxiv. 
p- 111), the species of Gentiana differ as much from each other 
as they do from most of the other genera of the Order.
