Notes
This species has been greatly confused, being still marked in most European herbaria, and by South African collectors, C. rubicundus, Vahl. From Vahl's description (as also from his West Indian locality) it is sufficiently clear that his C. rubicundus was not C. Teneriffæ; and from the type specimen in the Copenhagen herbarium, Vahl's C. rubicundus was C. brunneus, Swartz.
