The discovery of a typical member of tlie section Calyptrocliiliis in 

 Sumatra is very interesting, 



The short description of D. acf^^le RiDL. is somewliat suggestive of 

 this species, but the leaves are broader, the pedicels shorter; the bracts 

 lanceolate, the mentuni oniy '/, inch, the petals shorter and broader than 

 the sepals, the hp without a callus and the anther conic. 



The flowers are said to be violet. 



Description from a single dried spécimen, the flowers of which were 

 preserved in alcohol.
