flab. Arfak Mts., Koebré ridge between 9 and ¢ Angi lakes, epiphytic

The nearest ally of the species seems to be G. salicornioides J.J.S. This 
differs by the more robust stems, probably different-shaped leaves, colour of 
the flowers, much broader blade to the lip, and longer spur. 
I suppose that only the rooted upper parts of the stems were collected. 
The flowers are described as being white.
