The striking Bulbophyllum which forms the subject of 
our illustration is a member of a very distinct group of 
Malayan species which includes B, Pahudii, Reichb. f., 
B. Eriessoni, Kraenzl., figured at t. 8,088 and B. Bin- 
nendijkii, J. J. Sm., figured at t. 8,187 of this work. 
From the last-mentioned species, which is its nearest ally, 
our plant differs in a few minor structural details and in 
having flowers without spots. B. virescens was_ first 
described ten years ago from specimens collected on Mount 
Tuna in the island of Amboina, at about 2,500 feet above 
sea level. Shortly thereafter plants which, on flowering, 
proved to belong to this species were obtained by Messrs. 
Hugh Low & Co. from an island off the coast of New 
Guinea. ,The plant from which our figure has been 
made was acquired by purchase from Messrs. Low in 1905 ; 
it flowered in the tropical Orchid house at Kew in June, 
Aueust, 1910.
