摘要
本文描述并展示了印度北阿坎德邦的一个新物种--Geranium janakianum。本文提供了照片，并比较了该新分类群与形态上相似的 G. himalayense 和 G. wlassovianum 的诊断特征。这三个物种的特征是叶片掌状深裂，叶片裂片相对较少。不过，G. janakianum 与近亲的明显区别在于其叶片为五瓣，花瓣先端呈圆形，种子、分果爿和花粉都具有微形态特征，而且植株上到处都有气孔。
Geranium janakianum (Geraniaceae), a new species from Uttarakhand, India
A new species, Geranium janakianum, is described and illustrated here from Uttarakhand State, India. Photographs and a comparison of the diagnostic features of the new taxon with those of the morphologically similar species, G. himalayense and G. wlassovianum, are provided. These three species are characterised by palmatipartite leaves and relatively less lobed leaf segments. However, G. janakianum is clearly distinguished from its close relatives by having a pentamerous leaf lamina, rounded petal apex, micro-morphological features of the seed, mericarp and pollen in addition to the presence of stomata all over the plant.
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.
