Emilio Quisumbing, s. n., July 1929, on tree trunks in thick 
forests at low altitudes. Flowers fragrant, recalling the odor 
of Dendrobium anosmum Lindl. Peduncles pinard yellow; later¬ 
al sepals and dorsal sepal wax yellow on the back, mottled with 
amaranth purple, the apices suffused with bordeaux; the bases 
of the dorsal sepal and petals suffused with amaranth purple 
within; the petals white on the back; lip bordeaux half-way 
to the apex and pinard yellow at the base; column and foot 
pinard yellow. 
A species closely allied to Bulbophyllum copelandii Ames, dif¬ 
fering in its much larger leaves and flowers and in its differently 
shaped dorsal and lateral sepals, petals and labellum. The 
species is dedicated to Mr. Emilio Quisumbing, civil engineer, 
who collected the living specimens.
