ResumoRinorea domatiosa Van Wyk, a rare shrub or small tree endemic to the Table Mountain sandstone area of southern Natal and northern Transkei is described. It occurs in the understorey of evergreen forest and appears to be allied to R. angustifolia (Thouars) Baill. R. domatiosa is distinguished from R. angustifolia and all other southern African species of Rinorea mainly by its leaf blades with conspicuous hair-tuft domatia in the primary vein axils and epidermal cells with mucilaginous inner cell walls. A lectotype is selected for R. natalensis Engl. (currently included in the synonymy of R. angustifolia). Rinorea domatiosa Van Wyk, ’n seldsame struik of kleinerige boom endemies in die Tafelbergsandsteengebied van suidelike Natal en noordelike Transkei, word beskryf. Die spesie word in die laer stratum van immergroen woud aangetref en is waarskynlik naverwant aan R. angustifolia (Thouars) Baill. R. domatiosa word van R. angustifolia asook alle ander Rinorea-spesies in suidelike Afrika onderskei hoofsaaklik op grond van blaarlaminas met opvallende haarklossie-domatiums in die primêre aaroksels en epidermisselle waarvan die binnewande verslym. ’n Lektotipe word vir R. natalensis Engl. gekies (’n sinoniem vir R. angustifolia).
