Paul Ormerod (pers. comm.) never intended to propose this combination, which was inexplicably attributed to him by Szlachetko & Margonska.
Crepidium cordanthemon is reduced to Crepidium bisepalum. Both have connate lateral sepals, but otherwise appear to fit in section Pseudoliparis. They share the characteristic blue-green column with a dorsal appendage often found in that section. See also the images of a related, possibly undescribed species under the genus Crepidium.
