H. retusa var. nigra, Kransriviermond
Haworthia retusa var. nigra M.B.Bayer

nigra: black.

H. retusa var. nigra, previously described as variety of mutica, is kind of transition between retusa and mutica. It is generally non-proliferous species with rosette 6-8 cm in diameter. Leaves are light green to very dark green. It was originally described from Kransriviermond from a very dark clone = that´s why the name. However the rest of the population in other localities are "normal" green. 

Distribution area of var. nigra is around Heidelberg, to the South up to Kransriviermond, in the West up to half way to the Swellendam and to the East, to the Spitskop. It is much more widespread than first thought. Very strenge form is at Morning Star farm, where some clones are smooth and others very rough on leaves, may be it´s due to the near mirabilis population (300m). Near Spitskop, W of Riversdale occurs some intermediate forms with retusa, same as in population at Pienaarsrivier. NW of Heidelberg, at Klipdrift is a population with signs of turgida. I. Breuer use name H. chromutica for this species.

Some forms are very attractive and well known in cultivation. Propagation should be done by seed, leave offsetts or seldom by cuttings.
