﻿AbstractBased on examination of syntype specimens deposited at P, the lectotype for the nameDeutziasetchuenensisFranch. is designated here. By consulting literature and specimen records, the type locality ofD.setchuenensisvar.longidentataRehder, ‘Chin-Ting shan’ in the protologue is likely a misspelling of ‘Chiuting shan’ which is now called Jiuding shan located in southern Mao county, Sichuan province. In addition, a new variety,Deutziasetchuenensisvar.macrocarpaQ.L.Gan, Z.Y.Li & S.Z.Xu from western Hubei, Central China, is described and illustrated. It differs from other varieties ofD.setchuenensisFranch. by the orange anthers, broader outer filaments, obtuse inner filaments, and larger fruits.
