Caesalpinia bonduc is a climbing plant from the legume family (Fabaceae) that is found in the tropics of Africa, America and Asia.
description
Caesalpinia bonduc is a yellowish, fluffy hairy climber that forms straight or slightly curved spines . The leaves are bipinnate and 30 to 45 centimeters long. The leaf spindle is covered with curved spines. Six to nine pairs of opposite leaflets (higher-order leaflets) are formed. The stipules are large, leaf-like, usually lobed up to 2 centimeters long and fall off early. Six to twelve pairs of membranous leaflets are formed per leaflet. The leaflets are elongated, 1.5 to 4 inches long and 1.2 to 2 inches wide. The base of the leaflet is crooked, the end rounded to pointed and prickly. Both leaf sides are hairy downy.
Long-stemmed grapes growing in leaf axils are formed as inflorescences , which are only sparsely populated with flowers near the base and densely populated near the tip . The bracts are awl-shaped, 6 to 8 millimeters long, downy hairy and bent back. They fall off when the flowers open. The flower stalks are 3 to 5 millimeters long. The five sepals are about 8 millimeters long and hairy rust-red on both sides. The petals are yellowish, the flag is spotted red, obverse-lanceolate and nailed . The stamens are short and hairy near the base. The ovary is hairy. The fruits are elongated, 5 to 7 centimeters long and 4 to 5 centimeters wide, leathery legumes , which are densely covered with thin, 5 to 10 millimeter long spines. The tip is rounded and shows a beak. Two or three gray, shiny, egg-shaped to round seeds are formed per fruit .
Caesalpinia bonduc flowers in China in February and from July to October, the fruits ripen from October to May.
The number of chromosomes is 2n = 24.
