ID notes: Reddish pubescence is typical on abaxial surface of leaves, particularly on veins and in vein axil.
Origin/Endemic status: Endemic
Taxonomy Comments: Intermediate in morphology between C. aestivalis and C. opaca and demonstrated through genetic analysis to be of hybrid origin; the range is at the interface of the two parental mayhaw species. This taxon has been shown to be a triploid, while C. aestivalis and C. rufula are known diploids.
