查看更多>>摘要：A new endemic slipper orchid in the family Orchidaceae from Northern Thailand was described according to morphological and molecular analyses. Morphological information specifies the new slipper orchid Paphiopedilum charlesworthii var. lannaense to be similar to Paphiopedilum charlesworthii (Rolfe) Pfitzer 1895, with the exception of its staminode being obovate-obcordate with yellow color, glittery and rough surface. Molecular analysis by AFLP technique indicates that Paphiopedilum charlesworthii var. lannaense can be included as a member of section Paphiopedilum and is closely related to Paphiopedilum coccineum Perner, H. & Herrmann, R. (2000) (syn. Paphiopedilum barbigerum var. coccineum), from which it differs morphologically by dorsal sepal and petal characters. The morphological and molecular evidence supported that Paphiopedilum charlesworthii var. lannaense is a new slipper orchid in the genus Paphiopedilum (Cypripedioideae, Orchidaceae).
查看更多>>摘要：A taxonomic synopsis of the genus Cyanus in Turkey is presented. Cyanus hekimhanensis, C. cheiranthifolius var. purpurascens and C. reuterianus var. phrygius are proposed as new combinations. Some new synonymizations are proposed: Centaurea cana var. sultanensis with C. matthiolifolius, Centaurea pichleri var. ancyrensis with C. pichleri, Centaurea cana f. fulgens with C. triumfettii. Cyanus akcadaghensis is a synonym of C. matthiolifolius, Cyanus ermenekensis is a synonym of C. reuterianus, Cyanus banchevae is a synonym of C. thirkei. Lectotypes are designated here for ten accepted or synonymed names. The recognized taxa, the relevant synonyms, type details, lists of specimens examined, and a taxonomic key are provided for this genus in Turkey. In addition, the geographic distribution of all the taxa recognized in Turkey is presented and mapped.

Our recent investigation of Chinese liverworts found two interesting Riccia species, R. junghuhniana and Riccia subcrinita sp. nov. Riccia junghuhniana is currently known from Australia and Indonesia, while Riccia subcrinita is known only from China. Riccia subcrinita is similar to R. crinita, but differs in having smaller spores (56-71 mu m in diameter), and spore distal surface and proximal surface alveoli without thick borders. The sequences of rbcL, rps4, and trnL-F, detailed descriptions, and illustrations of the Chinese specimens are provided. The range extension of R. junghuhniana suggests that more taxa of Riccia may have a wider distribution. The discovery of R. junghuhniana and the new species also suggests that a more intensive survey of Riccia diversity in China is necessary.
查看更多>>摘要：Based on literature survey, examination of type specimens and fieldwork, seven names of Carex are synonymized in the present paper: viz. Carex hypoblephara reduced to a synonym of C. glossostigma; C. dayunshanensis and C. wuyishanensis to synonyms of C. graciliflora; C. dolichogyne to a synonym of C. truncatigluma; C. kwangtoushanica to a synonym of C. tatsiensis; and C. martini to a synonym of C. rhynchophora. The holotype of Carex fokienensis is identified and confirmed at P. The putative endemic species Carex macrosandra (basionym: C. lanceolata var. macrosandra) is synonymized to C. lanceolata, whereas C. cavaleriensis, considered a synonym of the former, is here recognized as a distinct species. A lectotype is designated for C. lanceolata var. macrosandra.
查看更多>>摘要：A novel species in Aspergillus section Fumigati is described as Aspergillus sibiricus. The new species was isolated from an open coal mine in Altai, Siberia, Russia and is represented by ex-type strain CBS 143307. We used a polyphasic taxonomic approach to characterise the species. A description based on morphological features is provided and shows that the new species differs morphologically from closely related species (A. assulatus, A. nishimurae and A. waksmanii). Partial sequences of the loci encoding beta-tubulin (BenA), calmodulin (CaM), ribosomal polymerase II second largest subunit (RPB2) and internal transcribed spacer rDNA region (ITS1-5.8S-ITS2) were analyzed as well. Sequences data, macro-and micromorphological and physiological characteristics distinguish A. sibiricus from all known species in section Fumigati, series Unilaterales. A. sibiricus, isolated from an acidic habitat (pH 3.2-3.4), is able to grow at pH 2 and is considered an acid-resistant species.
查看更多>>摘要：Based on literature survey and observations on herbarium specimens and living plants in the wild, we demonstrate that Anemone pindariensis (Ranunculaceae), most recently described from the western Himalaya in India, is a teratological form of A. rivularis. We therefore place the former in synonymy with the latter herein.
