Origin and Habitat: Prenia sladeniana is present widely in the winter rainfall areas of the Northern Cape (Richtersveld), and southern Namibia.
Habitat and ecology: Prenia sladeniana is common on the flanks of the mountains wher it covers large areas with its brick red leaves and its white flowers. They are pioneer plants which are also common on disturbed ground such as found along roads and airstrips. Prominent succulents in the same area include Ceraria fruticulosa, Ceraria namaquensis, Sarcocaulon crassicaule, and Sarcostemma viminale.
ENGLISH: rambling vygie
AFRIKAANS (Afrikaans): Skotteloor, klapiesvy
Description: Prenia sladeniana are ground hugging succulents with broad, flat, three-sided, pinkish leaves with red margins. The waxy, papillate leaves may tuft centrally, the plant producing flowering branches up to 400 mm long. Flowers are white (rarely pink) and appear from spring to autumn.
Stems: Firm creeping, vertically compressed (internodes barely visible). Prenia sladeniana also have the ability to transport stored water between leaves along the growth axis.
Derivation of specific name: Between 1908 and 1913, Professor H.H.W. Pearson organised five or six expeditions from Cape Town to Namaqualand, Namibia and Angola, with financial support from the Percy Sladen Memorial Fund. At least two species, Aloe sladeniana and Prenia sladeniana (Mesembryanthemaceae), were discovered on these expeditions and named after the financial benefactor.
