Abstract

We investigated the species composition of Saxifraga sect. Saxifraga subsect. Arachnoideae, a recently recognized taxon, using DNA sequence data (ITS, trnL–trnF, rpl32–trnL(uag)). We conclude that the subsection contains 12 species, i.e. S. aphylla, S. arachnoidea, S. berica, S. facchinii, S. hohenwartii, S. muscoides, S. paradoxa, S. petraea, S. prenja, S. presolanensis, S. sedoides and S. tenella. Of these, we provide the first molecular evidence for the membership of S. muscoides and S. prenja in S. subsect. Arachnoideae. We provide an extended morphological characterization of the subsection and an identification key to its species.

虎耳草科的物种组成。虎耳草亚目。基于DNA序列证据的蜘蛛目（虎耳草科）

研究了沙棘属植物的种类组成。利用DNA序列数据(ITS, trnL-trnF, rpl32-trnL (uag))对新近发现的蛛形纲分类单元进行了研究。该分节共包含葡萄球菌(S. aphylla)、蜘蛛球菌(S. arachnoidea)、berica、facchinii、hohenwartii、muscoides、S. paradoxa、S. petaea、S. prenja、S. preolanensis、S. sedoides和S. tenella 12种。其中，我们首次提供了葡萄球菌和葡萄球菌隶属于葡萄球菌亚组的分子证据。Arachnoideae。我们提供了一个扩展的形态特征的分段和识别关键的物种。

期刊介绍： Willdenowia is an international peer-reviewed journal publishing original research articles in English from the entire fields of plant, algal and fungal systematics, covering the evolution, taxonomy and nomenclature of these organisms as well as related fields such as floristics and plant geography. Articles on phylogeny and molecular systematics are especially welcome, as are review articles. Descriptions of new taxa may be considered, but only if supported by robust evidence. Narrowly regional studies of widespread taxa, routine typifications, checklists and new floristic records are generally not considered (excluding contributions to the Euro+Med-Checklist Notulae). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, in the Berlin herbarium (B).
