Notes.

In his publication elevating Croton brevispicatus var. isalensis to C. isalensis , Leandri (1972a) called the Perrier de la Bâthie 9788 specimen at P the holotype. We interpret this as a lectotypification of the taxon, and given that there appears to only be a single duplicate of Perrier de la Bâthie 9788 at P there is no need for a second-step lectotypification.
