Discussion:The var. tetrazyx is clearly different from var. vincentis, the form of Ch. mangense prevalent in Venezuela north of the Orinoco, in the few, very large, glabrous leaflets and in the relatively narrow pod. It has more in common with the distantly allopatric var. lentiscifolium, but even fewer and ampler leaflets.
