Hab.? (Cuit, in Hort. Bog. II M, b 34). 



Sumatra: Lampong. (Cuit, in Hort. S. Schogoers, Soekaboemi). 



This seems to be very near to D. bifidiim Ridl., but differs, as far 

 as can be traced from the very short description, in the blunt nientum and 

 the mucli longer not truncate lobes of the midlobe. 



Description from a living spécimen cultivated in the Buitenzorg Gar- 

 dens the origin of vi^hich is not known. 



For materials of the same species I am indebted to Mr. C. R. W. K. 

 VAN Alderwerelt VAN RosENBURGH, who found a plant, originating from 

 Southern Sumatra, cultivated in the garden of Mr. Schoggers, Soekaboemi. 

 The leaves of this spécimen were, however. longer and narrower than 

 those of the plant cultivated in Buitenzorg.
