摘要
Peliosanthes thachii 被描述为越南南部特有的一个新种,并配有插图。这是发现的 Neolourya 群的第五个物种,因为它的花柱纤细曲折,柱头位于花药上方,子房下位。新种在形态上与 P. curviandra 最为接近,但由于叶片和花部尺寸较小,花被球形且几乎不开放,花柱短且强烈扭曲,胚珠为紫色,因此可与该组的所有其他物种区分开来。本文提供了这一新分类群的物候学数据、分布情况以及对其保护状况的临时评估。
Peliosanthes thachii (Asparagaceae), a new species from Vietnam
Peliosanthes thachii is described and illustrated as a new species endemic to southern Vietnam. This is the fifth species found for the Neolourya group as it has a slender tortuous style with the stigma positioned above the level of anthers and an inferior ovary. The new species is morphologically closest to P. curviandra but it is distinguishable from all the others of the group by having smaller dimension leaves and floral parts, spherical and hardly open perianth, short and strongly tortous style and purple ovules. The data on phenology, distribution, and provisional assessment of conservation status of the new taxon are provided.
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.
