Croton ivohibensis var. integrifolius Radcl.-Sm., Gen. Croton Madag. Comoro 149. 2016

Type.

Madagascar. Prov. Toliara: bassin de réception de la Mananara, affluent du Mandrare, pentes occidentales des montagnes entre l’Andohahela et l’Elakelaka, Mt Apiky au dessus de Mahamava, 800-900 m, Jan-Feb 1934, H. Humbert 13821 (lectotype, designated here: P [P00133268]!; isolectotypes: P [P00133269]!, P [P00133270]!) .

Notes.

This is likely an undescribed species from the lower end of evergreen forests in southeastern Toliara Province. The pistillate flowers have a very long pedicel, and the calyx is very well developed. It is likely the same as C. nitidulus var. eglandulosus and C. Croton thouarsianus var. angustifolius (see below).
