Distribution. 



Java. Denu, 450 M., „in sylva virginea in collibus aridis. Flores toti 

 dare punicei, labello flavo, herba iuodora". BACKER 8S87, 20/8 1913. 

 Semel occursa. 



This new speceis is apparently very rare, as are the primaeval forests, 

 its habitat, in the lower mountain districts beneath 500 M. in West-Java, 

 and it seems to be endemic, at least it has not been described, either by 

 Ridley or by Schumann. 



it may be reduced almost with the same right to both Achasma 

 and Oeanthiis. To the first it belongs because of the showy vacous in- 

 volucralbracts, and the shape of the anther, to the latter because of the 

 want of a limbiform prolongation at the top of the labellum (called ap- 

 pendicula by Schumann). 



it cannot easily be reduced to Geantluis ( Elettaria) minuta BLUME, 

 because of the narrow half bifid labellum, with subulate lobes, ascribed 

 to that species by the author. 



It seems to show some affinity to Hornstedtia sanguinea RlDL, spe- 

 cim. in Herb. H. bog.
