Abstract

Based on literature consultation and specimen survey, we demonstrate that the Himalayan species Delphinium scabriflorum (Ranunculaceae) has been largely misunderstood. We agree with the previous treatment of placing D. altissimum in synonymy with D. scabriflorum. We determine that those specimens from Bhutan previously referred to D. scabriflorum and those from Cona in China’s southern Xizang (Tibet) previously referred to D. conaense or D. umbrosum var. drepanocentrum represent a new species, which we describe as D. pseudoscabriflorum herein. This species, currently known only from Bhutan and the closely adjacent Cona county in southern Xizang, China, is similar to D. ludlowii, a species endemic to Bhutan, and D. scabriflorum, a widely distributed Himalayan species, but differs by an array of characters with respect to leaf division, pedicel indumentum, shape of bracteoles and their position on the pedicel, shape of sepaline spurs, and follicle pubescence.

关于中国 Delphinium 属（毛茛科）的分类研究（XXVI）：D. altissimum 和 D. scabriflorum 的注释，并描述了一个新种 D. pseudoscabriflorum

根据文献查阅和标本调查，我们证明喜马拉雅物种Delphinium scabriflorum（毛茛科）在很大程度上被误解了。altissimum 与 D. scabriflorum 的同义关系。scabriflorum，以及中国西藏南部科纳的标本以前被称为 D. conaense 或 D. umbrosum var. drepanocentrum，我们将其描述为 D. pseudoscabriflorum。ludlowii和广泛分布于喜马拉雅山脉的D. scabriflorum相似，但在叶裂、花梗毛被、小苞片的形状及其在花梗上的位置、萼状距的形状以及蓇葖果的短柔毛等方面存在一系列特征差异。

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.
