The genus Frullania was previously known to be represented in the Fiji Islands by 20 species. From recent collections, 17 species were identified, of which five species proved to be new to the islands: Frullania angulistipa, Frullania baladina, Frullania chevalieri, Frullania ericoides, and Frullania gracilis. One other, Frullania vivipara, is described as new to science. The enumeration is followed by a phytogeographic evaluation.
