Basella is a small genus of five climbing succulent herbs in the family Basellaceae, order Caryophyllales. It is the type genus of its family, which is closely related to other succulent-leaved families within the Caryophyllales. The plants are characterized by twining stems, fleshy leaves, and small flowers, typical of the broader group of "fat plants" within this order.
Of the five recognized species, three are endemic to Madagascar, one (Basella paniculata) is restricted to southeastern Africa (Kenya, Tanzania, Mozambique, and South Africa), and one — Basella alba — has a wide native range spanning the Indian Subcontinent, Indochina, Malaysia, Indonesia, the Philippines, and New Guinea. Basella alba has also been widely naturalized through Africa, southern China, Central America, and various oceanic islands, largely owing to its long history of use as a leafy vegetable.
The genus name was drawn from the south Indian vernacular name "Basale," which the Flemish botanist Hendrik Adriaan van Rheede tot Drakenstein recorded in his encyclopaedic Hortus Malabaricus (1678–1703) as Basella. Linnaeus subsequently formalized the name when he described the genus.
Etymology
The genus name Basella originates from the south Indian vernacular name "Basale," recorded by Hendrik Rheede in his Hortus Malabaricus as the local name for the plant in Malabar (present-day Kerala). Linnaeus adopted and formalized this name for the genus.
Distribution
Basella has a fragmented native range: three species are endemic to Madagascar, one (B. paniculata) occurs in southeastern Africa (Kenya, Tanzania, Mozambique, and South Africa), and one (B. alba) is native to the Indian Subcontinent, Indochina, Malaysia, Indonesia, the Philippines, and New Guinea. Basella alba is now widely naturalized in Africa, southern China, Central America, and many oceanic islands.
Cultivation
Basella alba (Malabar spinach or Ceylon spinach) is widely cultivated as a fast-growing leafy vegetable in tropical and subtropical regions. It thrives in warm, humid conditions with full sun and well-drained soil, and is commonly grown on trellises or fences owing to its climbing habit.
Cultural Uses
Basella alba has a long history of use as a cooked leafy vegetable across South and Southeast Asia, where its thick, mucilaginous leaves are used in soups, stir-fries, and curries as a substitute for spinach. The plant also has recorded uses in traditional medicine in its native range.
