Herb. 82 Quisumbing, February 13, 1933, originally collected by 
Mr. L. Hachero from Surigao, Mindanao, presented to Doctor

A species with the habit of Dendrobium Dearei Reichb. f. and 
D. Sanderae Rolfe and allied to them, but differing strikingly 
in the short, obtuse spur. In addition to the different spur, 
this species differs from D. Dearei in having much larger flowers 
with different petals; it differs from D. Sanderae in the color 
and details of the flowers.
