Overlooked and misunderstood: A morpho‐molecular revision of Ditrichaceae s.str. (Dicranidae, Bryophyta), with a focus on the Holarctic species of Ditrichum

TAXON, Volume 74, Issue 2, Page 223-259, April 2025.
Abstract We revised the Holarctic taxa of Ditrichaceae on the basis of both organellar DNA sequence data and morphological traits. After the removal of phylogenetically discordant elements related to Flexitrichum and Rhamphidium, the remaining representatives of the family cluster into three well‐supported lineages, which are recognized here as the ...
