Two quite distinct species have been confused under 
the name Coelogyne sulphurea. The original was based 
upon Chelonanthera sulphurea, Blume, Bijdr. p. 283, a 
native of Java, but Sir J. D. Hooker afterwards included 
under the name a Perak plant which had been collected by 
Scortechini and Wray, and in this he was followed by Mr. 
H. N. Ridley, the latter pointing out that in some respects 
the species was almost intermediate between the genera 
Coelogyne and Pholidota. The late Dr. E. Pfitzer, in mono- 
graphing the Coelogyne group, proposed several new genera, 
and among them Chelonistele, in Engl. Pflanzenreich, Orch. 
Coelog. p. 136, to include Coelogyne sulphurea, Reich. f., 
and four other species, Chelonanthera being retained for 
Blume’s original Chelonanthera gibbosa and one other: but 
the differences between them are so slight that the old name
