Abstract

ABSTRACT Introduction While studying material of South American Syntrichia for a worldwide revision of the genus, we found that a specimen collected in Parinacota (Chile) did not match the concept of any species known in the genus. We present our argument for recognising this specimen of a South American Syntrichia from Chile as a new species and describe its differentiation from other closely related taxa. Methods About 3500 specimens from South America belonging to Syntrichia were studied, using conventional anatomical and morphological methods. Additionally, most of the type material of the taxa attributed to this genus, from throughout the world, was examined. Photographs of key features of the species were obtained for the preparation of illustrations for publication. Key results and conclusions A new moss species, Syntrichia splendida M.T.Gallego & M.J.Cano, from northern Chile, is described and illustrated. The species is strikingly distinguished by its abruptly contracted apices to a linear, pluricellular, papillose, mucronate, strongly toothed and chlorophyllose caducous propagule. Possible confusion with other closely related taxa is discussed.
智利北部的一个新苔藓物种——壮丽通丝藻M.T.Gallego和M.J.Cano(Pottiacee)
摘要引言在研究南美Syntricia的材料以进行该属的全球修订时,我们发现在智利Parinacota采集的一个标本与该属中任何已知物种的概念都不匹配。我们提出了我们的论点,认为来自智利的南美Syntrichia标本是一个新物种,并描述了它与其他密切相关类群的区别。方法采用传统的解剖学和形态学方法,对来自南美洲的约3500个Syntrichia标本进行了研究。此外,对来自世界各地的该属分类群的大多数类型材料进行了检查。获得了该物种主要特征的照片,用于准备出版插图。主要结果和结论描述并举例说明了智利北部的一个新苔藓物种——Syntricia splendida M.T.Gallego和M.J.Cano。该物种的显著特点是其顶端突然收缩为线性、多细胞、乳头状、短尖、强齿和叶绿素早落繁殖体。讨论了可能与其他亲缘关系密切的分类群混淆的问题。

期刊介绍: Journal of Bryology exists to promote the scientific study of bryophytes (mosses, peat-mosses, liverworts and hornworts) and to foster understanding of the wider aspects of bryology. Journal of Bryology is an international botanical periodical which publishes original research papers in cell biology, anatomy, development, genetics, physiology, chemistry, ecology, paleobotany, evolution, taxonomy, molecular systematics, applied biology, conservation, biomonitoring and biogeography of bryophytes, and also significant new check-lists and descriptive floras of poorly known regions and studies on the role of bryophytes in human affairs, and the lives of notable bryologists.
