Hob. Arfak Mts., Angi lakes, terrestrial in forest, 7000'. Fl., Fr. Dec. 

 5685, 5686, 5687, 5988, 6014, and 6140. 



Amongst the eleven numbers of this species collected, only one (viz. n. 5602) 

 is in habit very much like the type. The compact growth of both plants is 

 probably due to the fact that they were found in open ground, whereas the 

 other ones grew in the shade of the forest. 



The remaining ten numbers readily may be divided into two series the 

 one characterized by a tall stem and a short spur, the other by distinctly 

 shorter stem and a much longer spur. 



The flowers of all are green.

 specimen. " Labellum red, with green perianth."
