Watson (1878) treated Ptelea baldwinii Torr. View in CoL & A.Gray and “ P. baldwinii Young View in CoL ” as distinct names.The former he accepted and the latter he considered to be a synonym of P.angustifolia Benth. View in CoL [≡ P.trifoliata var. angustifolia (Benth.) M.E. Jones View in CoL ]. Watson’s synonymy was repeated in Index Kewensis ( Jackson, 1884) and adopted by IPNI (2021). Young’s name, however, is not a nomenclatural innovation, but simply a citation of the species described earlier by Torrey and Gray (1838). The description in Young (1873) matches verbatim that in the earlier flora except that the phrase “styles none” in the latter is corrupted to “style none” in the former. Young also suppressed the locality and collector information provided by Torrey and Gray (1838).
