Revision and checklist of the moss families Bartramiaceae and Mniaceae (Bryophyta) in Vietnam

Abstract

<p>The genera Fleischerobryum Loeske and Philonotis Brid. of the Bartramiaceae and the<br />family Mniaceae (excluding Pohlia Hedw.) are revised for Vietnam, based on specimens studied and<br />literature reports. Four species are added to the flora: Orthomnion javense (M.Fleisch.) T.J.Kop.,<br />Philonotis asperifolia Mitt., P. laii T.J.Kop., P. speciosa (Griff.) Mitt. syn. nov. (based on P. mercieri<br />Paris & Broth.), and Plagiomnium wui (T.J.Kop.) Y.J.Yi & S.He. Eight species are excluded from the<br />flora. Two taxa are considered doubtful. The flora now includes one species of Fleischerobryum, eight<br />species of Philonotis, one species of Mnium Hedw. (doubtful), three species of Orthomnion Wills. and<br />five species of Plagiomnium (one doubtful). The 15 species are divided into phytogeographical elements.<br />Eight belong to the Southeast Asiatic temperate to meridional element, and seven to the Southeast Asiatic<br />meridional to subtropical element. One species is pantropical and one is pansubtropical. The new finds<br />widen the distribution range of several species that were previously known only from North or South<br />Vietnam.<br /></p>
