Abstract

. In the course of a taxonomic study of the genus Cephaloziella (Spruce) Schiffn. (Cephaloziellaceae, Marchantiophyta) in Asia, the new species Cephaloziella konstantinovae Mamontov & Vilnet, sp. nov ., from the eastern regions of Russia and from the Republic of Mongolia was discovered. The new species is formally described and illustrated here. Morphologically it is similar to C. divaricata var . asperifolia (Taylor) Damsh. , but differs in its leaf shape and thin-walled, inflated stem and leaf cells. The new species can be distinguished from other Cephaloziella taxa by the following characters: ( i ) female bracts entirely free from each other and from bracteole, ( ii ) perianth campanulate, ( iii ) cells of perianth mouth subquadrate, ( iv ) capsule spherical, ( v ) seta with 8–10 + 4–6-seriate morphology, and ( vi ) elaters with 1–2 spiral bands. Molecular phylogenetic analyses of nrITS1-5.8S-ITS2 and chloroplast trn L-F sequences from 63 samples (34 species, 23 genera) confirm the taxonomical status of the new species. Five specimens of C. konstantinovae form a clade placed sister to a clade of C. elachista (J. B. Jack) Schiffn. and C. rubella (Nees) Warnst.

konstantinovae (cephalaloziella, Marchantiophyta)，俄罗斯和蒙古叶苔新种的综合分类鉴定

．在对云杉属的分类研究过程中。(cephalaloziellaceae, Marchantiophyta)在亚洲发现了新种cephalaloziella konstantinovae Mamontov & Vilnet, p. nov .，来自俄罗斯东部地区和蒙古共和国。这个新种在这里有正式的描述和说明。形态上与C. divaricata var相似。霉霉(霉霉)但不同的是其叶的形状和薄壁，膨大的茎和叶细胞。该新种与其他头孢菌属植物的特征有:(1)雌花苞片完全独立，苞片无苞片;(2)花被钟状;(3)花被口细胞近方形;(4)蒴果球形;(5)刚毛有8-10 + 4 - 6序列形态;(6)刚毛有1-2螺旋带。对63份样品(34种23属)的nrITS1-5.8S-ITS2和叶绿体trn L-F序列的分子系统发育分析证实了该新种的分类地位。5个康斯坦丁科的标本组成了一个分支，与C. elachista (J. B. Jack) Schiffn的分支有亲缘关系。和风疹c。
