Isonym is [plant:CampRadi] (L.) Bureau published in Monogr. Bignon. 2: 16 in 1864. Note from IPNI: Remarks: Bureau ascribed the comb. nov. to Seemann ("The Journ. of Bot., I, p. 19") and remarked "Bien que M. Seemann ne cite pas le nom de cette espece, il évidemment, et avec raison, l'intention de la comprendre dans le genre Campsis"(= Although Mr. Seemann doesn't cite the name of this species, he (had), evidently and with reason, the intention of including it with the genus Campsis); therefore, "ex" authorship is unwarranted.

Synonyms: Campsis curtisii Seem., Tecoma radicans (L.) Juss.
