: AmBOINA, Hatiwe, Robinson Pl. Rumph. Amb. 14, September 15, 1913, in 
light forests, altitude 250 meters. Flowers green, the column white. 
The nearest allies of this species are probably Habenaria dracaenifolia 
Schitr., H. keyensis Schitr., and H. bantamensis J. J. Sm. The specimen 
does not represent any of the species described by Rumphius as Doctor 
Robinson supposed. 
The plant differs from H. dracaenifolia in its smaller leaves, hardly 
acuminate sepals, the petals not cohering with the dorsal sepal, and pro- 
vided with a short enterior lacinia, shorter lateral lobes, and the spur
