Bednarek-Ochyra, H. 2018. The answer to the riddle of the taxonomic status of Bucklandiella bartramii (Bryophyta, Grimmiaceae). — Herzogia 31: 56–69.

The enigmatic species Bucklandiella bartramii from Tierra del Fuego is critically assessed and some details of its morphology and anatomy are illustrated. This moss was collected from wet sandy and gravelly soil on banks of an alpine rivulet and it exhibited a number of structural adaptations to rheophytic habitats. It is shown that this species is inseparable from B. orthotrichacea and these two species share distinctly recurved margins at leaf base, 2–3-seriate basal marginal borders of pellucid, hyaline and straight-walled cells and pseudopapillose laminal and costal epidermal cells. Accordingly, B. bartramii and B. orthotrichacea are considered synonymous, the latter name having priority. The current global distribution of B. orthotrichacea is reviewed and mapped.
