The Position of Lophozia dubia (Lophoziaceae, Marchantiophyta) in the Phylogenetic System of Lophozia and the Distribution of Lophozia in Southeast Eurasia, Extending to Indonesia.

Lophozia pallida, the commonly used name for a rare and little-known Sino-Himalayan species, was found to be a synonym of Lophozia dubia, a forgotten and previously misinterpreted species known in Indonesia. A comparative study of herbarium materials and our collections made it possible to 'extend' the distribution of Lophozia s. str. southward to Indonesia. The description of oil bodies from the species is provided for the first time. The position of the species in the Lophozia phylogenetic system demonstrates its clear differences from the morphologically similar Lophozia guttulata and its phylogenetic relationship with the Japanese-Korean Lophozia koreana.

Konstantinovia Is Not Monotypic, and a New Attempt to Determine Relationships in Cephaloziellaceae-Scapaniaceae Superclade (Marchantiophyta).

The exploration of liverworts on Bering Island (the westernmost Aleutians) has revealed plants assigned to the recently described and previously monotypic Konstantinovia, previously known only from Yunnan Province of China, and belonging to the bigeneric Obtusifoliaceae. The collected plants are described here as Konstantinovia beringii sp. nov. The known localities of two species of Konstantinovia are separated by more than 6000 km, while the presence of the genus on the Commander Islands is probably a relict. Phylogenetic examination of both collected specimens and new material from other related families resulted in the construction of a fairly well-supported phylogenetic tree for the entire Cephaloziellaceae s.l. + Scapaniaceae s.l. clade. The constructed trees have confirmed the previously stated assumption that it is necessary to segregate one more family within this superclade, described here as Oleolophoziaceae fam. nov.

Cembrane-type diterpenoids from the Chinese liverwort Chandonanthus birmensis.

A chemical investigation of the Chinese liverwort Chandonanthus birmensis Steph identified five undescribed cembrane-type diterpenoids, together with six known cembrane diterpenes, one fusicoccane-type diterpenoid, and a dolabellane-type diterpenoid. Their structures were established by comprehensive analysis of HRESIMS, NMR spectroscopic data, electronic circular dichroism (ECD) calculations and single-crystal X-ray diffraction analysis. Cytotoxicity tests of the isolated diterpenoids against five cancer cell lines (A2780, A549, H460, H460RT, and HeLa) revealed that several compounds showed moderate inhibitory effects with IC50 values ranging from 11.1 to 36.2 µM.
