This Brillantaisia plant is referred to as Brillantaisia subulugurica in Gauteng where it is widely grown.  This name appears to have been changed to B. cicatricosa. It is clearly different to the specimens of B. cicatricosa grown for instance in the Stellenbosch University Botanical Garden and depicted on the Internet. It is, however, a very attractive and easy to grow garden plant. It may be another species or a garden cultivar?
