The species are very difficult to discriminate, the flowers being much 

 alike in all. The above key is based almost wholly on the leaves, but I 

 am unable to determine the species by the venation-characters given in 

 Engler's recent monograph (Mon. Phan. iv. (1883). 



All our 13 species are endemic.
