Abstract

A revision of the genus Oreocomopsis was carried out based on the study of morphological, anatomical and molecular phylogenetic data based on ITS nrDNA sequences, of which the scope and composition were specified. The identity of O. xizangensis with the previously described O. dochenensis is shown; on the contrary, O. aromatica is singled out as an independent taxon. Ostericum scaberulum var. longiinvolucellatum is included in the genus Oreocomopsis as an independent species. Taxonomic features of the genus and differences from related genera are analysed. The species Oreocomopsis stelliphora has been assigned to the new genus Oreocomoides. The new genus Oreocomoides markedly differs from Oreocomopsis in many morphological characters, such as heterophyllous leaf blades: bipinnate in lower part and narrow-linear pinnate in upper part; bracts polymorphic, linear or pinnate with linear lobules; calyx teeth developed; petals with oval plate, at base with well-developed claw; pedicels rounded; mericarps ribs similar, narrowly-winged, slightly widened at the base.

Oreocomopsis 的系统发育和分类综述，以及新属 Oreocomoides 的描述（芹菜科，Apiaceae）。

在对形态学、解剖学和基于 ITS nrDNA 序列的分子系统学数据进行研究的基础上，对 Oreocomopsis 属进行了修订，明确了其范围和组成。结果表明，O. xizangensis 与之前描述过的 O. dochenensis 具有相同性；相反，O. aromatica 被单独列为一个独立的类群。Ostericum scaberulum var.分析了该属的分类特征以及与相关属的区别。种 Oreocomopsis stelliphora 被归入新属 Oreocomoides。新属 Oreocomoides 在许多形态特征上与 Oreocomopsis 明显不同，例如叶片异叶：下部为二回羽状，上部为窄线形羽状；苞片多态，线形或羽状，具线形小裂片；萼齿发达；花瓣具椭圆形板，基部具发达瓣爪；花梗圆形；分果爿棱相似，具狭翅，基部稍宽。

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.
