Discussion

Species ca. 15 (1 in the flora).

Trachelospermum asiaticum (Siebold & Zuccarini) Nakai (Asiatic jasmine) is widely planted as a ground cover in the southern United States and has been collected from Alabama and Texas but does not appear to be naturalized. It can be distinguished from T. jasminoides by the growth form and by stamens that are well exserted from the corolla, in contrast to the included stamens of T. jasminoides.
