Pachycarpus schinzianus - pink variety

 Family Apocynaceae

I have found two species of this flower.

This one found near Polokwane has pinkish flowers and the leaves are rimmed with purple.

 

For the white species, found near Pretoria, please see: http://natureswow2.blogspot.com/2012/04/cream-cups-pachycarpus-schinzianus.html
