The genus Mackfiya contains this one species only, and is named after Dr. 

 J. F. Mackay, author of the Flora Hibernica. M. bella is a handsome shrub, but 

 it has no economic value, it is found only in the coast and midland districts of 

 Natal, and does not seem to be very common. It is cultivated in Europe, having 

 been introduced from Natal in 1 869, and was figured in the Botanical Magazine,
