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 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.

Critical examination of herbarium specimens (including type material) of Cremanthodium ellisii var. roseum (Asteraceae, Senecioneae) has shown that the variety should be transferred to C. brunneopilosum. We therefore propose a new combination, C. brunneopilosum var. roseum.

Based on critical examination of herbarium specimens (including type material), we demonstrate that Clematis hainanensis (Ranunculaceae), described from Hainan in southern China, is not essentially different from C. leschenaultiana, a species widely distributed in China (Chongqing, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hubei, Hunan, Jiangxi, Sichuan, Taiwan, Yunnan), and also in Indonesia, the Philippines, and Vietnam. We therefore place C. hainanensis in synonymy with C. leschenaultiana herein. Lectotypification is proposed for C. leschenaultiana var. denticulata, which was described also from Hainan and treated as a synonym of C. leschenaultiana. The placement of the name C. splendens is briefly discussed.

Alpinia laosensis was previously placed in synonymy under A. conchigera. However, a critical examination of herbarium specimens (including type material) and living plants of A. laosensis and A. conchigera reveals that they are two separate species. Alpinia laosensis can be distinguished from A. conchigera by the shape of its fruits, shape and size of leaves and colour of labellum. We therefore reinstate A. laosensis as an independent species. A detailed description of A. laosensis together with a distribution map of both species are provided.

Senecio pentanthus (Asteraceae, Senecioneae) has been previously placed in synonymy with Synotis triligulata. Our critical examination of herbarium specimens (including type material) and living plants of S. pentanthus demonstrates that it can be easily distinguished from Syn. triligulata by the leaf serration and the number of phyllaries and florets. We therefore reinstate the independent specific status of S. pentanthus and propose a new combination, i.e. Syn. pentantha. Lectotypification is made for Syn. pentantha herein. A key to all the known species in Syn. ser. Microglossae and Syn. vagans, a species placed in Syn. ser. Erectae but actually more closely similar to those in the former series, is provided.

Critical examination of herbarium specimens (including type material) indicates that Thalictrum callianthum (Ranunculaceae), described from Mainling, south-east Xizang (Tibet), China, is conspecific with T. diffusiflorum, a species described from Nyingchi closely contiguous to Mainling and fairly common in south-east Xizang. We therefore place the former in synonymy with the latter.

Costus chinensis and C. oblongus (Costaceae) has been previously placed in synonymy under C. lacerus. Our critical examination of herbarium specimens including type material demonstrates that they are morphologically distinct from each other. Therefore, the independent specific status of C. chinensis and C. oblongus is reinstated. According to recent studies, Costus chinensis as well as other two Chinese species, C. oblongus and C. viridis, should be transferred to Hellenia. Thus, a new name for C. chinensis, and two new combinations are proposed. A detailed description of C. chinensis along with a distribution map of three allied species is also provided.
