摘要

本文记述了中国云南省一新种——夏金昌ense(兰科)。它在形态上与B. scabratum相似，但不同之处在于其自由(与收敛)的侧萼片，平均侧/背萼片长度的比例(约2.0 vs. 3.0)，紫红色(vs.淡黄赭色)的花。基于核糖体ITS和两个质体(matK和psbA-trnH)序列的系统发育分析支持B.夏金changense是一个独立的物种，与B. levinei、B. gedangense及其亲缘关系形成一个独立的姊妹谱系。

Bulbophyllum xiajinchangense (Orchidaceae; Malaxideae), a new species from China: evidence from morphological and DNA analysis

Bulbophyllum xiajinchangense (Orchidaceae), a new species from Yunnan province, China, is described and illustrated. It is morphologically similar to B. scabratum, but differs by its free (vs. convergent) lateral sepals, the ratio of mean lateral/dorsal sepal length (ca. 2.0 vs. ca. 3.0), purplish-red (vs. pale yellow-ochre) flowers. Phylogenetic analysis based on nuclear ribosomal ITS and two plastid (matK and psbA-trnH) sequences support B. xiajinchangense as a distinct species, which forms an independent lineage sister to B. levinei, B. gedangense and its allies.

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
