Cowpea (Vigna unguiculata) is an annual grain legume that is an important crop in many regions. The plant has been used as forage for animals and for cow feed. It can be short and bushy or grow as a long vine up to 2 m tall. The edible seeds and seed pods are very small and kidney-shaped.

Tabernaemontana ventricosa (commonly known as forest toad-tree or small-fruited toad-tree) is a plant in the family Apocynaceae. It grows as a shrub or small tree up to 15 metres (50 ft) tall, with a trunk diameter of up to 30 centimetres (12 in) and has white sap. Leaves are paired (set opposite each other) and crowded near the ends of branches. They are oblong, leathery and a glossy dark green. Flowers are fragrant with white, somewhat twisted lobes, often with a pale yellow center and are set in small clusters at the ends of branches. The fruit is dark green, set in spreading pairs of ellipsoids or oval, beaked pods, up to 10 centimetres (4 in) in diameter. Its habitat is forests from sea level to 1,850 metres (6,000 ft) altitude. In Zimbabwe, it is usually found as part of the understorey of evergreen forests. Local medicinal uses include the treatment of wounds, fever and hypertension. The plant is native to tropical central and southern Africa.

This South American plant is important in its native land, where it is a valued source of food and traditional medicine. It was also once the source of a toxin used for poison arrows. Pariparoba can produce stems up to 4 m high and will flower for most of the year in its ideal conditions.
