The taxonomy of the cliff fern family Woodsiaceae has been controversial with 22–59 species in 1–7 genera recognized in various classifications. This is mainly due to limited taxon sampling (up to 33 accessions representing up to 21 species) and poor resolution in molecular studies so far. In the present study, DNA sequences of five plastid markers (atpA, matK, rbcL, rps4 + rps4‐trnS, trnL + trnL‐F) of 152 accessions representing ca. 43 out of ca. 65 species estimated of Woodsiaceae (122 accessions), and 30 non‐Woodsiaceae accessions from the most closely related four families (Athyriaceae, Blechnaceae, Onocleaceae, Thelypteridaceae) were used to infer a phylogeny. Our major results include: (1) Woodsiaceae are strongly supported as monophyletic; (2) Two major clades representing the deepest split in Woodsiaceae are identified, corresponding to the two recently proposed subfamilies, Woodsioideae and Protowoodsioideae; (3) Within Woodsioideae and Protowoodsioideae, two and three well‐supported subclades, respectively, are determined; (4) Cheilanthopsis is resolved as paraphyletic in relation to Hymenocystis (sampled for the first time) and Protowoodsia; (5) Physematium and Woodsiopsis are paraphyletic in relation to a clade containing Cheilanthopsis, Hymenocystis, and Protowoodsia; (6) Evolution of 13 morphological characters is inferred in a phylogenetic context, and morphological synapomorphies of each of the five major subclades are identified; (7) We propose to recognize two genera in Woodsiaceae based on deep divergence (ca. 45 Ma), morphology, chromosome number, and geographic distribution: Physematium (syn.: Cheilanthopsis, Hymenocystis, Protowoodsia, Woodsiopsis) and Woodsia (syn.: Eriosoriopsis), and Physematium is further divided into three subgenera and Woodsia into two subgenera; (8) we describe ×Woodsimatium, a hybrid genus (nothogen. nov.) between the two genera recognized. A taxonomic synopsis of the family is provided, and 15 new combinations are made.

崖蕨科Woodsiaceae的整体质体系统发育和Woodsiaceae的两属分类，描述为×Woodsimatium nothogen。十一月

崖蕨科Woodsiaceae的分类学一直存在争议，在1-7种属中有22-59种被各种分类所认可。这主要是由于到目前为止，分类单元采样有限（多达33个种质代表多达21种），并且分子研究的分辨率较差。在本研究中，五个质体标记（atpA，matK，rbcL，rps4 + rps4-trnS，trnL + trnL-F的DNA序列）（代表ca.的152个种）。约43个。据估计，来自最紧密相关的四个科（Athyriaceae，Blechnaceae，Onocleaceae，Thelypteridaceae）的65种木科（122种）和30种非木科的种系用于推断系统发育。我们的主要研究结果包括：（1）大力支持单木科。（2）确定了代表伍德西亚科最深裂的两个主要进化枝，分别对应于最近提出的两个亚科：Woodsioideae和Protowoodsioideae；（3）在Wood科和原to科中，分别确定了两个和三个支撑良好的子小笼；（4）Cheilanthopsis是相对于解析为并系到Hymenocystis（采样的第一次）和Protowoodsia; （5）Physematium和Woodsiopsis是相对于包含一个进化枝并系Cheilanthopsis，Hymenocystis，和Protowoodsia ; （6）从系统发育的角度推断了13个形态特征的进化，并鉴定了5个主要子群中的每一个的形态同形。（7）我们建议根据深层发散（大约45 Ma），形态，染色体数和地理分布来识别Woodsiaceae中的两个属：Physematium（同名：Cheilanthopsis，Hymenocystis，Protowoodsia，Woodsiopsis）和Woodsia（同名：（Eriosoriopsis）和Physematium进一步分为三个亚属，Woodsia分为两个亚属；（8）我们描述了×Woodsimatium，这是公认的两个属的杂种（nothogen。nov。）。提供了该分类的概要，并制作了15种新组合。
