Sesamum radiatum is a species of flowering plant in the Pedaliaceae. It is in the same genus as sesame, and is known by the English common names benniseed, black benniseed,[2] black sesame,[3] and vegetable sesame.[4] It is native to west and central Africa, has been cultivated since ancient times in Africa, and is sometimes also used in tropical Asia where it has become naturalized to a small extent.[2]
Benniseed is a portmanteau of both the word benne and seed. Benne, meaning sesame derives from Gullah benne which is akin to Malinke bĕne.[5][6][7]
The seeds are eaten whole, made into a paste, ground into a powder, or pressed for a high-quality oil.[2] The leaves can be eaten fresh or cooked and are used in Sub-Saharan Africa as a leaf vegetable.[2][4] The leaves are mucilaginous in texture when cooked. The shoots can also be eaten and are used in soups and porridge.[8]
The leaves are also used medicinally as a laxative, an antidote to scorpion venom[3] and to treat sprains and ease childbirth.[3] The stem and bark have also been noted for their anti-bacterial properties.[9]
This plant is an annual herb growing up to 1.2 to 1.5 metres (3 ft 11 in to 4 ft 11 in) tall. The leaves are opposite, or toward the top of the plant, alternately arranged. The leaves are lance-shaped to oval and up to 12 centimetres (5 in) long. They may be smooth-edged or serrated. Flowers occur singly in the leaf axils. They are pink to purple in color, sometimes white, and somewhat bell-shaped. They measure up to 5 centimetres (2 in) long. The fruit is a capsule up to 3.5 centimetres (1+3⁄8 in) long which contains seeds roughly 3 millimetres (15⁄128 in) long.[2]
This plant grows wild in savanna and other habitat types. It is also a weed of fields and homesteads. It can grow on poor, rocky soils and it flowers even through drought conditions. When cultivated the plant yields 5 to 6 metric tons (5.5 to 6.6 short tons) of leaves per hectare.[2]
This plant is vulnerable to the leaf spot disease Cercospora sesami. It is also attacked by hawk moths (Sphingidae), the moth Antigastra catalaunalis, and the vegetable bug Nezara viridula.[2]
