Abstract
Abstract. Dicranum is one of the most diverse and widespread genera within the Dicranaceae. Species diversity and distribution in this genus, however, remain not well known. During our recent expeditions to the Hengduan Mountains in China, we found an interesting moss referrable to Dicranum species that is characterized by the stiff and fragile leaves, bistratose alar cells, and by the costal cross-section in the lower portion without stereid bands with one layer of cells above and below guide cells. Morphological and molecular-phylogenetic analyses based on five chloroplast markers (rpoB, rps4-trnT, rps19-rpl2, trnH-psbA, and trnL-trnF) and one nuclear marker (ITS region) suggest that this unknown moss represents a new species here described as D. hengduanensis. The plastome of this new species presented in this study is the first complete plastome of Dicranum.
期刊介绍：
The Bryologist is an international journal devoted to all aspects of bryology and lichenology, and we welcome reviews, research papers and short communications from all members of American Bryological and Lichenological Society (ABLS). We also publish lists of current literature, book reviews and news items about members and event. All back issues of the journal are maintained electronically. The first issue of The Bryologist was published in 1898, with the formation of the Society.
Author instructions are available from the journal website and the manuscript submission site, each of which is listed at the ABLS.org website.
All submissions to the journal are subject to at least two peer reviews, and both the reviews and the identities of reviewers are treated confidentially. Reviewers are asked to acknowledge possible conflicts of interest and to provide strictly objective assessments of the suitability and scholarly merit of the submissions under review.
