Fockea is a genus of succulent scrubs native to Africa south of the equator. Of the six recognized species, only the two most widely distributed (F. angustifolia and F. multiflora) extend north of southern Africa, both reaching as far north as Tanzania.[1] Fockea are known as water roots,[2], a reference to their characteristic bulbous caudex, which is edible in at least some species.
Taxonomy
Most Fockea species are relatively small climbers with swollen, mostly subterranean tubers, whereas Fockea multiflora, a widely distributed but exclusively tropical species, is a massive, tropical liana without a tuber. It is considered a sister to the other five species. Fockea angustifolia, also widely distributed, is mainly tropical, and sister to the remaining four species, which are endemic to southern Africa.[1]
- Fockea angustifolia K.Schum. — A climbing tuberous geophyte found primarily in the seasonally dry tropical biome, ranging from Southeast Kenya to South Africa.[5]
- Fockea capensis Endl. — A climbing tuberous geophyte found primarily in the subtropical biome; its native range is the southern Cape Provinces of South Africa.[6]
- Fockea comaru (E.Mey.) N.E.Br. - A tuberous geophyte found primarily in the desert or dry shrubland biome, ranging from southern Namibia to South Africa's Cape Provinces.[7]
- Fockea edulis (Thunb.) K.Schum. - A climbing tuberous geophyte found primarily in the subtropical biome, ranging from the southern Cape Provinces to KwaZulu-Natal in South Africa.[8]
- Fockea multiflora K.Schum. - A semisucculent liana growing primarily in the seasonally dry tropical biome, ranging from Tanzania to northern Namibia.[9]
- Fockea sinuata (E.Mey.) Druce - A climbing tuberous geophyte growing primarily in the in the desert or dry shrubland biome, ranging from south-central and southern Namibia to the Cape Provinces and Free State province of South Africa.[10]
