FRULLANIA (FRULLANIACEAE, MARCHANTIOPHYTA) IN HAWAII

Abstract

  A revision of Frullania Raddi in Hawaii is presented. Six species are recognized: F. apiculata (Reinw. et al.) Nees, F. crenatiloba Steph., F. hypoleuca Nees, F. meyeniana Lindenb., F. oahuensis Hampe ex Gottsche, Lindenb. & Nees, and F. sandvicensis Ångstr. Frullania crenatiloba and F. sandvicensis are reinstated as distinct species. Frullania hawaiiensis H.A.Miller and F. angstromii A.Evans ex Steph. are synonymized with F. crenatiloba and F. sandvicensis respectively. Frullania ericoides (Nees) Mont. and F. neurota Taylor are excluded from the Hawaiian bryoflora. Brief descriptions and photomicrographs for all the species of the region are provided, as well as a key differentiating between the different taxa.
