The description of D. nycteridoglossum Rchb. f., which is said to be of 

 Papuan origin, more or less fits this plant. As, however, the description 

 is very poor and the exactness of the information about the origin is very 

 uncertain, further comparison with that species is for the present useless. 



The material was very poor, and especially the description of the lip 

 wants further confirmation. 



The flowers are said to be yellow.

Though I now think that this plant is not a form of Eria rigida Bl., I 

 quote it under the above name because I do not yet wholly understand 

 Schlechter's Papuan species of this group.
