opens, and shed the pollen on the lip. The second day 

 the filaments contract and curl up and the stigma ap- 

 pears at the mouth of the flower. 



Didymocarpus (§ Bceopsis). 



I propose this section of Didymocarpus for a number 

 of small species with the short corolla-tube and two 

 short stamens with thick sigmoid filaments and sub- 

 globose or elliptic anthers. The form of the flowers 

 and habit of the plants is exactly like that of Saint- 

 paulia, an African genus, and that genus only differs 

 in the thick conic capsule. It would probably be better 

 to separate the section above, mentioned into a distinct 

 genus, Baeop>sis, but there are intermediate links with 

 the long tubed /. idymocarpi. The section would include. 

 D. perdita Ridl., D. puncticulata Ridl., D. heterophylla 

 Ridl., and the following new species from the island 

 Pulau Eattam, south of Singapore.

Leaves elliptic obovate 2 to 3 inches long 1^ inch
