On rocks in quickly flowing water. Only met with in two localities, both 

 in Koh Chang, viz. Klong Majum alt. 700 ft. and Klong Sarlakpet alt. 600 ft. in 

 small waterfalls in the jungle ; it does not grow where the stream is less rapid. 

 The specimens from Klong Majum were collected on February 23 rd and were ste- 

 rile, whereas those from Klong Sarlakpet found on March 15 th bore flowers and 

 unripe fruit which extended above the surface of the running water.
