NOTES ON FIVE FRULLANIA SPECIES FROM AUSTRALIA, INCLUDING TYPIFICATION, SYNONYMS, AND NEW LOCALITIES

抄録

  There are approximately 65 taxa from the liverwort genus Frullania that have been reported for the Australian botanical region. This study discusses aspects relating to five Frullania species, including features associated with the sporophyte which have not previously been investigated. First, we report F. incumbens as a new record for Australia; second, we re-evaluate the taxonomic status of the F. pentapleura species complex; Frullania wildii is subsequently reduced to a synonym of F. pentapleura, and both F. pentapleura and F. probosciphora are recognised at the species level. Finally, notes are provided for F. apiculata and F. hypoleuca; two widespread but poorly described species.
