Note
|
This species is similar to Teramnus labialis but differs in leaf shape, longer pedicels and in the upper calyx teeth being fused for all or most of their length. It is possible that the two species intergrade. Teramnus volubilis ranges throughout the Caribbean area, but appears to be somewhat rare.
