Psychotria capensis (SA Tree No. 723) has two subspecies (ssp. capensis with flower stalks and ssp. riparia without), each of which also with at least two variations as well. Plants with such large distribution areas as this tree, covering great variety in factors such as climatic conditions, elevation, pollinator species, soil types and competing vegetation, can be expected to end up with variety in its evolutionary adaptations as well. A specimen like the one in picture, living well at Kirstenbosch (beyond the confines of its habitat, but clearly thriving), can look quite different to one that ekes out an existence in the hot and dry parts of Limpopo or Mpumalanga (Coates Palgrave, 2002).
