Abstract

Background and aims: Juncus is the largest and most diverse genus of Juncaceae, distributed mainly in the temperate zones of both hemispheres. The Southern Cone flora contains ca. 38 Juncus species (44 taxa including 12 infraspecific categories). Sixteen of those species belong to the section Ozophyllum. As a part of our ecologic studies in wetlands of Patagonia (Argentina) we collected specimens of Juncus that did not match any of the species currently known to the Southern Cone. The aim of this contribution is to report for the first time the presence of Juncus articulatus subsp. articulatus for the Southern Cone flora. M&M: Classical methods in taxonomy were employed. Living and herbarium material, original descriptions, and type material of Juncus articulatus subsp. articulatus were studied. Collected materials were deposited in the herbarium ARC of the Universidad Nacional del Comahue. Results: Juncus articulatus subsp. articulatus is here described. A distribution map, photos, and a key to the Southern Cone species of Juncus belonging to the section Ozophyllum are provided. Also, some ecological and distributional features are discussed. Conclusions: The naturalization of Juncus articulatus subsp. articulatus is reported here for the first time in the Southern Cone. From now on, Juncus contributes 39 species to the Southern Cone flora, and 17 to Juncus section Ozophyllum.

关节结亚属首次记录。南锥体植物区系的关节属植物

背景与目的:菊花属是菊花科中最大、种类最多的属，主要分布在南北半球的温带地区。南锥植物区系约有38种球果属植物(44个分类群，包括12个次种)。其中十六种属于臭氧门。作为我们在巴塔哥尼亚(阿根廷)湿地生态研究的一部分，我们收集了与南锥体目前已知的任何物种都不匹配的Juncus标本。这篇文章的目的是首次报道关节球的存在。南锥体植物区系的节肢动物。M&M:采用经典分类学方法。朱鹭的生物和植物标本馆资料、原始描述和类型资料。研究了关节鱼。收集到的材料存放在Comahue国立大学的ARC植物标本室。结果:关节小结;这里描述的是关节鱼。本文提供了一份属于臭氧门的球果属南锥种的分布图、照片和钥匙。此外，还讨论了一些生态和分布特征。结论:关节小关节的归化。这里是南锥首次报道的关节鱼。从现在开始，在南锥体植物区系中有39种，在臭氧区系中有17种。

期刊介绍： Bol. Soc. Argent. Bot. publishes original scientific works from the whole spectrum of Plant Biology (structure, anatomy, development, physiology, cytology, genetics, evolution, ecology, paleobotany, palynology, ethnobotany, etc.) in the diverse vegetable organisms and related groups (mycology, ficology, lichenology, briology, etc.), both in basic and applied aspects. Taxonomic works (of systematics, phylogeny, monographs, revisions, lectotypifications, nomenclatural acts, descriptions of taxa), phytogeographic and phytosociological works (survey and classification of vegetation at different spatial scales and without restriction of methodological approaches) are considered for publication. Contributions that address complete phytogeographic units or sub-units and those that fill gaps in knowledge of vegetation in little-known territories are especially welcome. Extensions of geographical areas are published only when it comes to new citations for a country. Checklists and lists of annotated plants are not published. Articles submitted for publication must be original and must not have been submitted to another publisher or previously published (print or electronic format). Submissions of papers already published in another language will not be accepted (autoplagio for translation).
