Differs from all the species of Anoectochilus by the mesochil which is 

 not afforded with pectinate lobes, but has broadly entire wiugformed lobes, 

 by the columnal appendages which are doubly folded and beak-shaped at 

 the apex, and by the triangular lateral lobes at the mouth of the spurs. 

 It may constitute a new genus (Aviglossum, I should propose to call it), when 

 the above mentioned characters are fully ascertained by the study of a 

 living material.
