Known only from Amboina.

India to the Malay Archipelago and the Philippines. The Amboina 

 specimen, cited above, is apparently this species, at least as currently 

 interpreted.

Amboina, Soja road, Rel. Robins. 1766, August 1, 1913, on grassy dry 

 hillsides, altitude about 300 meters. 



The discovery of this species in Amboina, a characteristic Australian 

 type, is of some interest. Doctor Robinson had previously collected it in 

 Guimaras Island, Philippines, and wrote regarding the discovery of it 

 in Amboina, that on the first of August he located a region that strongly 

 resembled the place in Guimaras where he had found Stackhousia and de- 

 liberately commenced a search for the plant, succeeding in finding it in 

 quantity. It is inconspicuous, slender, and grows among grasses, which 

 perhaps explains why it has not been discovered more frequently. It is 

 known from northern Luzon and from Guimaras Island in the Philippines, 

 from Yap Island in the Carolines, from Amboina, and from northeastern 

 Australia, with a closely allied or identical form in Sumatra.

 a diagnosis of it is not at present available.
