Psychotria capensis The Bird-berry ("Psychotria capensis" ) is a southern African evergreen shrub or small tree. It belongs to a genus which is used medicinally in many regions, 'Psychotria' being from the Greek for 'rejuvenating', in reference to the healing properties of certain species. Kew lists some 2,000 species of "Psychotria" growing throughout the warmer regions of both hemispheres, but only two of them occur in southern Africa, namely "P. capensis" and "P. zombamontana".
