Abstract

The genus Marchantia occurs world-wide. The greatest diversity of described species occurs in the tropical Pacific. Fourteen species of Marchantia have been reported at different times from the Hawaiian Islands but when this study began seven species were recognized. A new technique for clearing thallus material enabled me to see and compare ambiguous characters. From studies of types and numerous additional collections from the islands, I determined that the seven species accepted actually belong to three taxa and one previously undescribed species was discovered. Comparison of Hawaiian plants with specimens, drawings and descriptions of extra-Hawaiian Marchantiae showed clearly that the Hawaiian species are predominantly like those of New Guinea and the Indo-Pacific region. However, one tropical American species, Marchantia paleacea, does occur in Hawaii.
