There are 11 genera and 39 species, mainly
occurring in the fynbos of the Western Cape in South Africa but with
some representatives distributed through Africa, Madagascar, the
Mascarene Islands and southern Arabia. There are genera and
species indigenous to southern Africa. From recent molecular
studies, the genera Halleria, Charadrophila, Bowkeria, Anastrabe
and Ixianthes have been moved to this family from the
Scrophulariaceae and Nuxia has been moved from Loganiaceae to
Buddlejaceae to its present home in the Stilbaceae.
Retzia
capensis, the sole member of its genus,
