Calea tricephala is most closely related to C. lucidivenia Gl. & Blake of 

 Auyan-tepui, Uaipan-tepiu , and Cerro Guaiquinima, all in the State of Bolivar. 

 For this latter species Gleason and Blake suggest a close affinity with C. trianae 

 var. tolimensis Hieron. of Colombia. The Venezuelan species, at least, show 

 further strong relationship with C. myrtifolia (DC.) Bak. of Minas Geraes, Brazil. 



Stenopadus Blake.
