A genus of deciduous climbers closely related to Actinidia, but differing in the flower having ten stamens and one style, whereas in Actinidia both stamens and styles are numerous; the pith, too, of Actinidia is sometimes lamellate but always continuous in Clematoclethra. About twenty-five species are known, all Asiatic. Wilson found eight of them in China. They are easily cultivated in free, loamy soil, but the introduced species are rather tender and need the shelter of a wall. Easily propagated by late summer cuttings in gentle bottom heat.
