xi. c, 5 Merrill: Reliquiae Robinsonianae 267 



Wedd. in DC. Prodr. 16 * (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.

ELATOSTEMATOIDES POLIONURUM (Hallier f.) comb. nov. 



Elatostema polioneurum Hallier f. in Fedde Repert. 2 (1906) 62. 



Amboina, Hatiwe and Kati-kati, Rel. Robins. 181b, 1917, September and 

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



Amboina and Celebes; very closely allied to the Philippine Elatostema-

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.
