Alba forms of Cym canaliculatum

[Cym Ladye]

Andrew,

I am certainly not the expert on describing a species but in my experience, once the species itself has been described, all different color forms are merely absorbed into the species and referenced only as "varieties". They are not separately described.

In this case, the absence of anthrocyanin (red color) in all the flower segments, especially in the lip, is what determines the "alba" varietal designation.
