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.

Delphinium ellipticovatum, D. tianshanicum and D. winklerianum (Ranunculaceae) share some important characters in leaf division, pedicel pubescence and the shape of the spur of upper sepals. They have been considered to be different mainly in the characters of bracteoles (shape, size, indumentum, and position on pedicels). Our critical observations on herbarium specimens (including type material) and living plants, together with numerical analyses of the bracteole characters within and between populations of the species in question, have demonstrated that, in addition to D. kuanii previously already synonymized with D. winklerianum, both D. ellipticovatum and D. tianshanicum are also indistinguishable from D. winklerianum. We therefore further place D. ellipticovatum and D. tianshanicum also in synonymy with D. winklerianum.

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 living plants in the field, together with examination of herbarium specimens (including type material), we demonstrate that Delphinium iliense (Ranunculaceae) is highly variable in the indumentum of peduncles, pedicels, bracteoles, sepals and carpels and also in the shape of bracteoles and their position on pedicels. We therefore redefine this species and, in addition to accepting some previous synonyms in this species, such as D. longiciliatum and D. turkestanicum, we further reduce D. iliense var. angustatum and D. naviculare to its synonymy. We also propose lectotypification for D. iliense var. angustatum and D. turkestanicum.

Based on examination of herbarium specimens (including type material), we found that Delphinium calthifolium (Ranunculaceae), described from northern Sichuan in China, is conspecific with D. sinovitifolium, a species known only from its type material and misunderstood for a long time. We therefore place D. calthifolium in synonymy with D. sinovitifolium herein.

Delphinium aktoense, D. kaschgaricum, D. kunlunshanicum, D. wuqiaense and D. zhangii (Ranunculaceae) were all described from the region of eastern Pamir-western Kunlun Shan in western Xinjiang, China. Critical observations on both herbarium specimens (including type material) and living plants demonstrate that they are indistinguishable from each other and are all conspecific with D. afghanicum, a species previously known only from Afghanistan.

Delphinium taxkorganense, D. tetragynum and D. yechengense (Ranunculaceae) were all described from western Xinjiang, China. Critical observations on both herbarium specimens (including type material) and living plants demonstrate that they are indistinguishable from each other and are conspecific with D. lacostei. We therefore place them into the synonymy of D. lacostei, the earliest name.

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.

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.

Background: Ongoing taxonomic studies in the African genus Arctotis (Asteraceae) necessitate periodic nomenclatural adjustments and corrections.Objectives: To evaluate the taxonomic status and application of the name Arctotis grandiflora Aiton.Methods: Type material and herbarium specimens were located and examined, relevant literature was consulted and wild populations were observed.Results: The type material of A. grandiflora Aiton comprises specimens of two taxa from independent gatherings. A lectotype is designated for A. grandiflora.Conclusion: The name A. grandiflora Aiton is a heterotypic synonym of Arctotis stoechadifolia P.J.Bergius. A revised synonymy for A. stoechadifolia is presented.
