This species was found mingled with specimens oiDendrobium 

 Eurorum Ames. The type consists of three plants preserved in 

 my herbarium. D. interjectum is a close ally of D. angust'ifolium. 

 From dried specimens the flowers appear to have been whitish 

 or yellowish, with the apical third of the labellum yellow and the 

 basal two-thirds deep purple. Through the basal portion of the 

 labellum run two raised lines which suddenly dilate at the base 

 of the midlobe into large deep purple lamellas. The midnerve of 

 the labellum is prominent.
