Wedd. in DC. Prodr. 16 1 (1869) 173. I cannot distinguish the Amboina 
material from authentically named -Javan specimens representing Miquel’s 
species. 
ELATOSTEMA sp. 
Amboina, Salahoetoe, Rel. Robins. 1912, on rocks in ravines, altitude 
200 meters, November 27, 1913. 
A small, slender plant, perhaps undescribed, but the material is rather 
scanty.

October, 1913, along streams, altitude 10 to 70 meters.

HELICIA Loureiro 
HELICIA MOLUCCANA (R. Br.) Blume in Ann. Sci. Nat. II 1 (1834) 216. 
Rhopala moluccana R. Br. in Trans. Linn. Soc. 10 (1811) 191. 
Amboina, Hitoe messen, Rel. Robins. 1657, October 13, 1913, in forests, 
altitude about 200 meters. 
The type of this species was from Amboina. Its further distribution 
in the Moluccas is uncertain, as it has been reported only from Amboina.
