Plants from Weixi Xian, in NW Yunnan, have been separated as Saxifraga implicans var. weixiensis on account of its stem being glabrous proximally, but since the stem hairs on this species are known to be glabrescent (Smith, loc. cit.), it seems probable that this very minor variation is related to age or environment.
