Abstract

This paper is the first in a projected series of publications treating the Chenopodiaceae in South America. We present here a taxonomic revision of subfamilies Betoideae, Camphorosmoideae, and Salsoloideae in South America, where all representatives of these subfamilies are introduced. Our research is based on the study of herbarium material, type specimens, digital images, original publications, and field observations. The South American Chenopodiaceae flora includes only Beta vulgaris L. from Betoideae, Bassia hyssopifolia (Pall.) Kuntze, Bassia scoparia (L.) A. J. Scott, and Maireana brevifolia (R. Br.) P. G. Wilson from Camphorosmoideae, and Salsola kali L., Salsola tragus L., and Soda inermis Fourr. from Salsoloideae. Lectotypes for Echinopsilon reuterianus Boiss., Kochia alata Bates, K. parodii Aellen, K. parodii var. elongata Aellen, K. parodii var. densa Aellen, K. parodii var. glabrescens Aellen, and Suaeda sieversiana Pall. are designated here, as well as a second-step lectotype for K. brevifolia R. Br. The distribution of all species is updated based on the revision and proper identification of many herbarium specimens and field observations. The distribution of M. brevifolia in Chile is here expanded. New synonyms for Bassia scoparia are proposed. A preliminary key to the genera of Chenopodiaceae in South America is also presented.

南美洲藜科分类学的更新Ⅰ：桦总科、花总科和水松总科

这篇论文是关于南美洲藜科的一系列出版物中的第一篇。我们在这里对南美洲的Betoideae、Camphorosmoideae和Salsoloideae亚科进行了分类修订，介绍了这些亚科的所有代表。我们的研究基于对植物标本馆材料、模式标本、数字图像、原始出版物和实地观察的研究。南美藜科植物区系仅包括Betoideae的Beta vulgaris L.、Bassia hysopifolia（Pall.）Kuntze、Bassia scopearia（L.）A.J.Scott和Camphorosmoideae的Maireana brevifolia（R.Br.）P.G.Wilson，以及Salsola kali L.、Salsola tragus L.和Soda inermis Fourr。来自Salsoloideae。勒氏棘皮虫的Lectotypes。，Kochia alata Bates、K.parodii Aellen、K.paradii var.elongata Aellen，K.parodiii var.densa Aellen、K.parodii var.glabrescens Aellen和Suaeda sieversiana Pall。以及短叶K.brevifolia R.Br的第二步选择型。根据对许多植物标本馆标本的修订和正确鉴定以及实地观察，更新了所有物种的分布。短叶M.brevifolia在智利的分布在这里得到了扩展。文章提出了新的东莨菪同义词。还介绍了南美洲藜科各属的初步检索表。

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.
