Based on critical observations on herbarium specimens (including type material) and living plants in the wild, we demonstrate that Thalictrum panzhihuaense (Ranunculaceae), described from Panzhihua city in southwestern Sichuan province, China, is conspecific with T. glandulosissimum and that T. tsaii, described from Weixi county in northwestern Yunnan province, China, is extremely close to T. glandulosissimum. We therefore place T. panzhihuaense in synonymy with T. glandulosissimum and treat T. tsaii as a variety of T. glandulosissimum, i.e. T. glandulosissimum var. tsaii. The identity of T. glandulosissimum var. chaotungense is also discussed. Lectotypification is proposed for T. glandulosissimum.

Based on critical observations on herbarium specimens (including type material) and living plants in the wild from its type locality, we demonstrate that Thalictrum kangdingense, recently described from Kangding county in western Sichuan province, China, is readily distinguishable from T. xinningense by an array of morphological characters but is actually conspecific with T. megalostigma, a species with its type locality also in Kangding. We therefore reduce T. kangdingense to the synonymy of T. megalostigma herein. The morphological distinction between T. baicalense and T. megalostigma is also clarified.

Based on critical observations on both herbarium specimens (including type material) and living plants in the wild, we demonstrate that Thalictrum brevisericeum var. pentagynum, described recently from Heishui county in northwestern Sichuan province, China, is identical with T. uncinulatum, a widely distributed Chinese species. We therefore reduce T. brevisericeum var. pentagynum as a synonym of T. uncinulatum herein. Lectotypification is proposed for T. uncinulatum.

Based on examination of herbarium specimens (including type material), we demonstrate that Delphinium breviscaposum and D. filibracteolum (Ranunculaceae), both described recently from northwestern Yunnan in China, are conspecific with D. ceratophorum and D. bulleyanum, respectively, two species very common in northwestern Yunnan. We therefore synonymize D. breviscaposum and D. filibracteolum herein. Second step lectotypifications are proposed for both D. bulleyanum and D. ceratophorum.

Examination of herbarium specimens (including type material) has shown that Anemone weixiensis, recently described from Weixi County in northwestern Yunnan, China, is conspecific with A. flaccida, a species widely distributed in China, Japan and Russia (Far East) and fairly common in northwestern Yunnan. We therefore place A. weixiensis in synonymy with A. flaccida. As A. flaccida belongs to A. sect. Keiskea based on molecular work, we reduce A. sect. Deinostigma, which was established to accommodate A. weixiensis, to the synonymy of A. sect. Keiskea.

Thalictrum semiscandens (Ranunculaceae) was described from Lushui County in northwestern Yunnan, China and has been almost totally overlooked since its publication. Based on a critical examination on herbarium specimens (including type material), we demonstrate that it is conspecific with T. trichopus, a species widely distributed in southwestern China (Sichuan and Yunnan). We therefore reduce T. semiscandens to the synonymy of T. trichopus herein. Lectotypification is proposed for T. trichopus.

Based on observations on both herbarium specimens (including type material) and living plants in the wild, we demonstrate that Artemisia sichuanensis var. sichuanensis (Asteraceae, Anthemideae) differs from A. sichuanensis var. tomentosa only by the leaves abaxially sparsely pubescent (vs. densely gray arachnoid tomentose). In addition, A. erlangshanensis is found to be identical with A. sichuanensis var. tomentosa, and is thus synonymized herein.

Based on observations on herbarium specimens (including type material) and living plants in the wild, we demonstrate that Artemisia flaccida (Asteraceae, Anthemideae) is conspecific with A. fulgens and that A. flaccida var. meiguensis deserves a varietal status under A. fulgens. We therefore place A. flaccida in synonymy with A. fulgens and transfer A. flaccida var. meiguensis to A. fulgens as A. fulgens var. meiguensis. Lectotypification is proposed for A. fulgens and A. flaccida. The geographical distribution of the two varieties of A. fulgens, var. fulgens and var. meiguensis, is also clarified.

Based on critical observations on both herbarium specimens (including type material) and living plants in the wild, here we clarify some morphological characters in the Chinese species Thalictrum przewalskii (Ranunculaceae) and demonstrate that T. lasiogynum and T. latistylum, described respectively from China’s Sichuan and Gansu provinces, are conspecific with it. We therefore reduce T. lasiogynum and T. latistylum to the synonymy of T. przewalskii. Thalictrum sect. Platystylus, which was established to accommodate T. latistylum, is reduced to the synonymy under T. sect. Omalophysa. The identity of T. rockii is further confirmed and the distribution in China of T. sparsiflorum, a species most closely similar to T. przewalskii and widely distributed in northeastern Asia and North America, is also determined.

We therefore reduce T. jilongense and T. tenuicaule to the synonymy of T. leuconotum herein. Lectotypification is proposed for T. leuconotum.
