Borovichev, E. A. & Bakalin, V. A. 2016. On Mannia triandra (Aytoniaceae, Marchantiophyta) in Eastern Asia. — Herzogia 29: 59–65.
Mannia triandra is a rare and poorly known taxon in Asia. Some specimens of this species have been misidentified and considered as other taxa and vice versa. During fieldwork and herbarium studies, we revealed hitherto unknown occurrences of M. triandra in Magadan Province and the Korean Peninsula. The locality in the Republic of Korea belongs to a so-called wind-hole area and confirms the high value of such kind of habitats at low elevations in temperate East Asia as refugia for rare alpine plants. The paper provides a morphological description and figures based on the studied collections and reviews the ecological preferences and distribution of M. triandra in eastern Asia.
