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.
