摘要

摘要贫血症是巴西种类最多的属之一，约有60种。与许多其他蕨类植物不同，银莲花的种类在干燥和岩石环境中丰富，其中许多是巴西中部塞拉多山脉的狭窄特有种。除了其丰富性外，几种银莲花还可以杂交，杂交种和多倍体在该属中相当常见。在对塞拉多最北端分布的实地考察中，我们发现了一个我们在这里描述的未描述的物种——阿氏银莲花。我们还描述了一个新的杂交种，银莲花×pirenopolitana，介于秀丽银莲花分支中的两个物种之间，这是该分支中杂交种的第一个记录。我们提供了新分类群的形态描述和插图、分布图，以及与最相似物种的比较。此外，还提供了秀丽银莲花分支中该物种的关键。

Novelties in the Anemia elegans Clade (Anemiaceae), with a New Species and Nothospecies from Brazil

Abstract Anemia is one of the most diverse genera in Brazil, with about 60 species. Unlike many other ferns, species of Anemia are abundant in dry and rocky environments, with many of them being narrow endemics to the mountains of the Central Brazilian Cerrado. Besides its richness, several species of Anemia hybridize, and hybrids and polyploids are fairly common in the genus. During a field trip to the northernmost distribution of the Cerrado, we found an undescribed species that we describe herein – Anemia areniticola. We also describe a new hybrid, Anemia ×pirenopolitana, between two species in the Anemia elegans clade, which is the first record of a hybrid in this clade. We provide morphological descriptions and illustrations, and distribution maps for the new taxa, as well as comparisons with the most similar species. A key is also provided for the species in the Anemia elegans clade.
