A native of the mountains of Java, to which island it 
appears to be confined, this distinct species, which was dis- 
covered by Teijsmann and Binnendijk, and described by 
them more than half a century ago, long remained prac- 
tically unknown in Europe, and has but recently been intro- 
duced to cultivation. The plant from which the figure now 
given has been prepared was presented to Kew in 1908 by 
the Hon. W. Rothschild, Tring, and flowered in the tropical 
orchid collection in June, 1909. C. biflorum is, perhaps, 
most nearly allied to C. picturatum, Lodd. (Bulbophyllum 
icturatum, Reichb. f.), a native of Tenasserim, figured at 
t. 6802 of this work, but is very easily distinguished by the 
characters noted by Mr. Rolfe. The most striking feature 
in our plant is the constantly 2-flowered scape, to which it 
owes its name, and on account of which it serves as a link 
between the group of forms with solitary flowers, referred io 
at t. 8199, and those species that possess the umbellate 
inflorescence at one time thought characteristic of the 
genus, The difficult question as to whether the genus Cirrho-
