1 There are considerably more names published in this genus than recognisable species but the patterns of variation have not been adequately studied. Most of these names pertain to taxa in Japan and China. The synonyms given for the taxa below are not intended to be exhaustive and I have included only those for which I have had ready access to the type material and could confirm their status. A more thorough synonymy must await a comprehensive revision of the genus. 2 Recent research has confirmed that the North American Trachelospermum difforme is not closely related to the Asian taxa and should be treated in the genus Thrysanthella.
