Abstract
The genus Aptenia Brown (1925: 412) (Aizoaceae Juss.), native to southern Africa, comprises four species according to Gerbaulet (2017: 117). Aptenia cordifolia (Linnaeus filius 1782: 260) Schwantes (1928: 69) and A. haeckeliana (Berger 1910: 224) Bittrich ex Gerbaulet (2001: 68) are the parents of the hybrid material from which the cultivar Aptenia ‘Red Apple’ was selected (Brown Folsom et al. 1995: 169).
