The paper provides the results of a recent collaborative Russian-Chinese exploration of the Guizhou hepatic flora in southern China. In total, 99 species are listed, with seven species newly recorded for China (Calypogeia angusta, Cordaea flotoviana, Mesoptychia chinensis, M. ussuriensis, Lophozia silvicola, Riccia nipponica, and Riccardia nagasakiensis) and 12 others new for the Guizhou Province. Presence of regenerative structures in the specimens examined, distribution in four studied localities, the elevation, ecology and associated species are provided for each species. Oil bodies of 54 species are illustrated by color photographs. РезюмеИзложены результаты совместной российско-китайской экспедиции по изучению печеночников провинции Гуичжоу (южный Китай). Составленный по материалам экспедиции список включает 99 видов из которых 7 (Calypogeia angusta, Cordaea flotoviana, Mesoptychia chinensis, M. ussuriensis, Lophozia silvicola, Riccia nipponica, Riccardia nagasakiensis) -приводятся впервые для Китая и еще 12 -для провинции Гуичжоу. Каждый вид в списке аннотирован, по изученным образцам, сведениями об экологии, высотном диапазоне произрастания и присутствии генера-тивных структур. Приводятся фотографии масляных тельц 54 видов по изученному материалу.

The new checklist of Putorana liverworts was compiled based on examination of recent collections and summarizing of literature data. It includes 118 species, 47 of them are new for the plateau. The most interesting records are Odontoschisma francisci, Saccobasis polymorpha, Endogemma caespiticia and Marchantia romanica. The occurrence of 26 taxa mentioned in the literature was not re-confirmed. In general terms, the flora is typical for continental Hemiarctic with very limited number of taxa showing East Asian (Apotreubia nana) and amphi-oceanic (Cordaea flotoviana, Lophozia savicziae, Odontoschisma francisci, Saccobasis polymorpha) distribution. РезюмеСоставлен новый аннотированный список печеночников плато Путорана, основанный как на недавних коллекциях, так и на обобщении литературных данных. Список включает 118 видов, в том числе 47 приводятся для плато впервые. Наиболее интересными находками являются Odontoschisma francisci, Saccobasis polymorpha, Endogemma caespiticia и Marchantia romanica. Распространение 26 видов, указанных в литературе, не подтверждено, и часть из них могла быть приведена на основании ошибочных определений. В общих чертах флора типична для континентальной Гипоарктики с ограниченным количеством видов, показыва-ющих восточноазиатские (Apotreubia nana) или амфиокеанические (Cordaea flotoviana, Lophozia savicziae, Odontoschisma francisci, Saccobasis polymorpha) связи гепатикофлоры.

In the course of revision of Marchantiales for the Russian Far East, Wiesnerella denudata, the only species of the monotypic family Wiesnerellaceae is recorded for the first time in Russia. The plant has been found in Iturup and Shikotan Islands of South Kurils), and this is the northernmost locality in the world, the nearest previously known locality being in Honshu in Japan and on the southern tip of the Korean Peninsula. The morphological description and figures based on specimens from Russia are provided. РезюмеВ ходе проведения ревизии порядка Marchantiales для российского Дальнего Востока, в двух образцах собранных на Южных Курилах (острова Итуруп и Шикотан), выявлено новое для России монотипное семейство печеночников Wiesnerellaceae. Для единственного вида семейства, Wiesnerella denudata -это самое северное местонахождение в мире. Ближайшие районы, из которых этот вид известен, находятся на о-ве Хонсю (Япония) и юге Корейского полуострова. Приводится описание вида, иллюстрации, обсуждается распространение. KEYWORDS: Wiesnerella denudata, Wiesnerellaceae, the Russian Far East, distribution, taxonomy, HepaticaeThe family Wiesnerellaceae iincludes the only one species, Wiesnerella denudata (Mitt.) Steph. The genus Wiesnerella was described by Schiffner (1896), based on the collection from Javanese volcano Gedeh (=Gede), where it was collected in inner side of crater. Already in the time of gathering Schiffner has realized that the plant as a very peculiar one. As he wrote, by the general habit of vegetative plants Wiesnerella resembled Lunularia, but without semi-crescentic gemmae cups characteristic to the latter. Within Wiesnerella Schiffner (l.c.) described the only W. javanica Schiffn. Later Stephani (1898) transferred Dumortiera denudata Mitt. described from the East Himalayas (Mitten, 1861) to Wiesnerella and synonymized it with W. javanica with the former as priority.One more species of the genus has been described from Xizang Province of China, Wiesnerella fasciaria (Gao & al., 1981). According to the original description and illustrations (Gao & al., 1981), W. fasciaria differs from W. denudata in (1) having narrower thallus -30 mm length and 2 mm width; (2) having dark green band in the midline of thallus dorsal surface; (3) very elevated pores above epidermis surrounded by 6 concentric rows of 6 cells in each. However our observations and cited literature indicate that the above mentioned features are very variable and W. fasciaria may be regarded as a form of W. denudata from shady and wet place. Probably this results the acceptance of Wiesnerella in the current classification is as a monospecific genus (Bischler, 1998;Frey, 2009), although nobody formally still not synonymized 2 E.A. BOROVICHEV & V.A. BAKALIN W. fasciaria with W. denudata . We were not able to study the type of W. fasciaria and regard it as a synonym of W. denudata provisionally.The main characteristics of Wiesnerella include: (1) simple air pores; (2) ventral scales in 2 rows, each with single appendage; (3) sporophytes...

Identification of a small collection of thallose liverworts from Inner Mongolia (China) has revealed Clevea pusilla (Steph.) Rubasinghe & D.G. Long, the species new for the province, rare and poorly known Himalaya-East Asian taxon variably treated in the current literature. A morphological description, illustrations and differentiating characters from closely related C. nana (Shimizu & S. Hatt.) Borovich. & Bakalin and C. spathysii (Lindenb.) Müll. Frib. are provided. Резюме Обработка небольшой коллекции слоевищных печеночников порядка Marchantiales из Внутренней Монголии (Китай) позволила выявить новый для этой провинции, редкий и малоизученный вид-Clevea pusilla (Steph.) Rubasinghe & D.G. Long, объем которого, в настоящее время, крайне дискуссионен. Приводятся морфологическое описание, отличия от C. nana (Shimizu & S. Hatt.) Borovich. & Bakalin и C. spathysii (Lindenb.) Müll. Frib. и оригинальные иллюстрации.
