A genus of two Asiatic species, distinct from all other members of the Lardizabala family in their shrubby (not climbing) habit, in their pinnate (not palmately compound) leaves and their bisexual flowers. The name commemorates Joseph Decaisne (1807-82), at one time Director of the Jardin des Plantes, Paris.
