Two New Species of Lophozia (Marchantiophyta) from the Sino-Himalaya and the Taxonomic Diversity of East Asian Lophozia

An integrative study of material from Yunnan Province, China, revealed two new <i>Lophozia</i> species. These species and several other representatives of the genus known from East Asia form a distinct clade within the phylogenetic structure of <i>Lophozia</i>. Descriptions, photographs, and comments regarding the morphological characteristics of the new taxa are provided. <i>Lophozia neglecta</i> is characterized by pink gemmae (another taxon with similar gemmae is East Asian <i>L. koreana</i>), whereas <i>L. vinacea</i> is characterized by vine-purple gemmae, which were previously unknown in the genus. Additionally, molecular analysis confirmed the occurrence of <i>L. fuscovirens,</i> a poorly known <i>Lophozia</i> taxon with brown gemmae, in the Kamchatka Peninsula. The taxonomic diversity of <i>Lophozia</i> in East Asia comprises 12 species belonging to various distribution groups, including the Sino-Himalayan and broadly East Asian groups.
