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.

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.

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.

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.

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.

Taxonomic studies on monosporic pure cultures of Australian isolates of Stemphylium revealed the presence of three species, namely S. botryosum, S. globuliferum and S. vesicarium. A group intermedi- ate between S. botryosum and S. vesicarium but more closely resembling S. vesicarium was recognised. The circumscription of S. vesicarium was broadened to accommodate this taxon which was found on Medicago sativa, M. rugosa and Simmondsia chinensis. Studies on herbarium specimens deposited as S. botryosum on M. sativa from a number of overseas locations indicated that in all cases the pathogen fitted our concept of S. vesicarium. Teleomorphs were induced in pure culture for each of the above-mentioned anamorphs, and in all instances the teleomorph was identified as Pleospora herbarum. The ascospore morphology was similar for all isolates, and the shape of the ends of the spore and the number of longitudinal septa were variable characters even within an isolate. However, the teleomorphs could be separated into two distinct groups on the basis of ascal length.

Knowledge about the sponge fauna from the Mexican Pacific Ocean has increased substantially in recent years, but most of these modern taxonomic studies have been focused on hadromerids. The aim of this study was to contribute to the knowledge of the order Poecilosclerida. At present, seven species of Mycale have been described or recorded from the Pacific coast of Mexico, but only three of them are considered valid: M. contax, M. cecilia and M. aff. magnirhaphidifera. After a revision of the material collected during the last eight years throughout the East Pacific coast of Mexico, along with the type material, and the literature available, eight species of Mycale are considered valid, three of them; M. magnitoxa sp. nov., M. dickinsoni sp. nov., and M. ramulosa sp. nov., are proposed as new to science. In addition, M. adhaerens is reported for the first time from the Mexican Pacific Ocean. Another Mycale-species that was identified was M. psila, which constitutes its seconLamberd record for the Mexican Pacific Ocean. The systematic, distribution and detailed species descriptions are based on newly collected material and previous descriptions from the literature.
