A checklist of the liverworts and hornworts of Dominica, West Indies

Two hundred eighty eight liverwort species and seven infraspecific taxa in 27 families and 83 genera, and five hornwort species in four families and five genera are currently accepted for Dominica. At least 14 taxa mentioned in the Dominica literature have not been treated in recent revisions and need taxonomic verification, are doubtful records or have been excluded. Genera and species are arranged in alphabetical order. For each accepted taxon the basionym is cited and the synonyms that are based on specimens from Dominica. Furtheron, data on illustrations are presented, and eight new records are incorporated (Leiosporoceros dussii, Phaeoceros carolinianus, Aneura pinguis Bazzania cuneistipula, Harpalejeunea uncinata, Lejeunea huctumalcensis, Metzgeria ciliata, and Microlejeunea epiphylla). The list is complemented by some notes on geography, geology and climate, a bryogeographical survey, a short history of hepaticological exploration, and a taxonomic arrangement of the families and genera. Two new combinations, Riccardia dilatata (Aneura dilatata) and R. ligulata (A. ligulata) are made.
