plant, but is only iiMerfectlj known. Planchon (Hook. Lond, Journ. Bot. v. 64) sug- 

 psts that it may be Gomphia sumatranUj with which, however, the description of the 

 jeares does not appear to agree. Wallich describes it as having elhptic-lanceolate 

 leaves tapering at both ends, finely acuminate, sharply and minutely serrulate, the 

 nerves reticulating and uniting in two or more submarginal arches. — Native of Sinca- 

 pore and the contiguous islands.
