 epiphytic in forest, 7000-8000'. Fl. Dec. 5547. 



The flower recalls very much that of D. angiense J. J. S., but the habit of 

 the plant is very different. I do not know whether the plant is indeed a 

 small one or that only the end of a stem was collected. 



The colour of the flower is described as red.
