Abstract

Abstract The genus Pseudognaphalium Kirp., segregated from Gnaphalium L., is one of the largest genera of the tribe Gnaphalieae (Asteraceae) with about 60 species, most of them found in South, Central, and North America, but some species also occurring in Africa, Asia, Europe, and New Zealand. We present a taxonomic revision of Pseudognaphalium for North America accepting 36 species, mainly distributed in the Nearctic Region and the Mexican Transition Zone, and about one third of the species occurring in the Neotropical Region. The following taxa are newly synonymized: G. oaxacanum Greenm. with P. semiamplexicaule (DC.) Anderb., G. schraderi DC. with P. attenuatum (DC.) Anderb. var. sylvicola (McVaugh) Hinojosa & Villaseñor, P. altamiranum (Greenm.) Anderb. with P. roseum (Kunth) Anderb., and P. beneolens (Davidson) Anderb. with P. thermale (E. E. Nelson) G. L. Nesom. Lectotypes are newly designated for G. oblanceolatum Greenm., G. panniforme S. F. Blake, G. ramosissimum Nutt., G. roseum Kunth var. angustifolium Benth., G. roseum var. hololeucum Benth., and G. roseum var. sordescens Benth. Morphological descriptions are provided as well as taxonomic data on nomenclatural types, including synonymies, illustrations, distribution maps, distribution and habitat, additional material examined, distinguishing characters and taxonomic affinities for each taxon, biogeographical and ecological comments, and a key for their identification.

标题北美拟龙蝇属(菊科，龙蝇科)的分类订正

文章摘要假信号藻属。，与Gnaphalium L.分离，是Gnaphalieae（菊科）部落中最大的属之一，约有60种，其中大多数分布在南美洲、中美洲和北美洲，但也有一些物种分布在非洲、亚洲、欧洲和新西兰。我们对北美洲的Pseudomonaphalum进行了分类修订，接受了36个物种，主要分布在近北地区和墨西哥过渡区，约三分之一的物种分布在新热带地区。以下分类群是新的同义词：G.oaxacanum Greenm。与P.semi-implexicule（D..）Anderb。，G.schraderi DC。与P.attenum（DC）Anderb。变种sylvicola（McVaugh）Hinojosa&Villaseñor，P.altamiranum（Greenm.Anderb）。与P.roseum（Kunth）Anderb。，和P.beneolens（Davidson）Anderb。与P.thermale（E.E.Nelson）G.L.Nesom。新命名了G.oblanceolatum Greenm。，梨形目S.F.Blake。，G.roseum Kunth var.angustifolium Benth。，G.roseum var.hololeucum Benth。，和G.roseum var.sordescens Benth。提供了形态学描述以及命名类型的分类数据，包括同义词、插图、分布图、分布和栖息地、检查的额外材料、每个分类单元的区别特征和分类亲缘关系、生物地理和生态评论，以及识别它们的关键。

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
