Abstract

Based on the examination of herbarium material, the extant distribution of Acrolejeunea sandvicensis is shown to be disjunctive between subtropical East Asia and Hawaii. All tropical records of the species with one exception (southern India: Palani Hills) are erroneous. Close similarity to the fossil A. ucrainica may indicate that the species was widespread in the Holarctic during the Tertiary. The Asia-Hawaii disjunct plant relationships, especially liverworts, are briefly discussed. Verification of published records is essential for the assessment of the geographical ranges of species and is a key step towards the prediction of the species occurrences.
