Based on observations on herbarium specimens (including type material) and living plants in the wild, we demonstrate that Artemisia taibaishanensis (Asteraceae, Anthemideae) is conspecific with A. qinlingensis. We therefore place A. taibaishanensis in the synonymy of A. qinlingensis herein. Lectotypification is proposed for A. qinlingensis and its geographical distribution is also clarified.

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 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, 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 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 field observations and examinations of herbarium specimens (including type material), consulting the original literature and molecular phylogenetic analysis of the rbcL and trnL-F sequences, it is concluded that Hypolepisrobusta is conspecific with Hypolepisalpina and is here formally treated as a synonym of it. Additionally H.alpina is reported with new distribution records in Guangdong, Guangxi and the Hainan Island of China, respectively.

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.

Based on critical observations on herbarium specimens (including type material) and living plants in the wild, we demonstrate that Thalictrum jilongense and T. tenuicaule (Ranunculaceae), described from southern Xizang (Tibet) and western Sichuan, China, respectively, are both conspecific with T. leuconotum. We therefore reduce T. jilongense and T. tenuicaule to the synonymy of T. leuconotum herein. Lectotypification is proposed for T. leuconotum.

We have previously placed Thalictrum austrotibeticum (Ranunculaceae) in synonymy with T. neurocarpum. Based on critical observations on herbarium specimens and living plants in the wild, we demonstrate that T. punduanum var. hirtellum, recently described from southern Xizang (Tibet), China, is also identical with T. neurocarpum. We therefore reduce T. punduanum var. hirtellum to the synonymy of T. neurocarpum herein. We also further clarify the morphological distinction between T. neurocarpum and T. reniforme, which were often regarded as conspecific.

Ranunculus kangmaensis (Ranunculaceae) was recently described from Kangmar (= Kangma) in Xizang (Tibet), China. Based on critical observations on herbarium specimens and living plants in the wild, together with evidence from achene surface morphology and karyology, we demonstrate that it does not belong to the genus Ranunculus but is identical with Halerpestes tricuspis var. variifolia. We therefore place R. kangmaensis in synonymy with H. tricuspis var. variifolia herein.

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.
