This has hitherto been placed with ©. bulbosum, Schimp. in a section 
characterised by the exserted corolla-scales, but with that species it has no 
other affinity. It differs from it fundamentally in the fusiform root, the 
branched stem, and the many-flowered racemes. From ©, pseudobulbosum, 
Azn., which has slightly exserted corolla-seales, it is distinguished by the 
more slender habit, the wingless stem, and the deeply divided ealyx.
