Notes on Ceramium (Rhodophyta: Ceramiales) from the Hawaiian Islands

Abstract

Ceramium is widely distributed and recorded from the coasts of the North Pacific Ocean. Thus, it is not surprising to find new species and new records of this genus among the numerous islands spread in this oceanic region. Extensive examination of material collected around O'ahu and other Hawaiian Islands has yielded two new records: Ceramium aduncum Nakamura (previously known from Japan), Ceramium clarionensis Setchell & Gardner (previously recorded for the Pacific coast of Mexico), and a new species, Ceramium cingulum Meneses.
