sensu Bunge, Enum. pl. China bor. 45. 1833 (Mém. Acad. Imp. Sci. St.-Pétersbourg Divers Savans 2:119. 1835)
Comment:
Bunge applied Catalpa syringifolia Sims (an illegitimate, superfluous name for C. bignonioides Walter), which Sims had applied to a N. American & Japanese taxon, to a Chinese plant, but didn't exclude Sims's type, so his is not a new name
