Members of Flemingia are shrubs, or herbs (or subshrubs); evergreen, or deciduous and perennial. They are generally about 0.2–1.5 m high. The stem is prostrate but weak. Leaves are small to medium-sized; not fasciculate, but alternate. The stem and leaves are pubescent, with dense hairs. Leaf blades are flat dorsoventrally. Flowers are aggregated in ‘inflorescences’; not crowded at the stem bases; in racemes, or in heads, or in panicles. Fruits are aerial, about 6–15 mm long; non-fleshy and hairy.
