 Lamarck founded Canscora and the species C. perfoliata on Kheede 1. c. ; Grisebach 

 says the calyx is exalate, in direct opposition to Rheede's figure and description ; 

 moreover the size of the calyx and corolla and whole habit of the plant in Rheede 

 shows that his figure means the Pladera perfoliata of the old collectors.
