C. hmenlom, Liiull, Folia Oix-liid 3, is descri])od as liaving a 

 toinojitose ovary and three keels on the \\\). It was collected Ijy Lohh, 

 Xo. 1ST oi' his collection and has no localit}^ on the specimen, C. 

 ])(i!/ana is not tomentose at all, but the rachis and ovary are covered 

 with a nigrohirsute pubescence, and has five keels on the lip. C. 

 Massangeana, Echb. til. has been a very puzzling plant on account of 

 the fact that it has been confused with typical Dayana. Hooker 

 (Bot. Mag. t. GT99) states that it is not nigrohirsute; Williams' 

 Orchid album gives it as nigrohirsute (Orchid Album t. 29). The 

 original plant had short bulbs and broad leaves, but plants from the 

 Larut Hills with the tiowers of C. Massangeana, have the pseudobulbs 

 and leaves of 0. Dayana. The coalescence of the ridges on the disc 

 seem to be the only distinguishing point.
