Annotated Checklist of Hawaiian Mosses

Forty years have passed since Bartram (1933) published the only comprehensive moss flora for the Hawaiian Islands. Since then, numerous articles which are relevant to our area have appeared list-ing additional taxa, new island records, and differing nomenclature. As a result, the Manual of Hawaiian Mosses has been rendered in-creasingly difficult for all but specialists to use. The purpose of this checklist is to gather together information from publications of the last four decades and thus to present in a single treatment our knowledge of the Hawaiian moss flora. As a re-sult, it is hoped the scattered literature will no longer pose such a serious problem for either the amateur or professional student of this very interesting component of the Hawaiian biota. In turn it is further hoped that many valuable collections which even today remain un-identified may be examined and a better understanding of the Ha-waiian moss flora emerge. Accepted in this list are 255 species, varieties, and forms distrib-uted in 38 families and 123 genera. Their post-1933 synonymy, island-by-island distribution, and the references upon which these records are based have been indicated. In addition, there are taxa in Ectro-pothecium, Entodon, and Fissidens which appear to be new and will be described in forthcoming papers. For nomenclature, the Index Muscorum (van der Wijk, 1959-1969) has been followed. Author ab-breviation citations follow Sayre, Bonner & Culberson (1964); journal abbreviations are generally those of the Index Muscorum. For syn-onymy, two general classes are recognized. For nomenclature syn-onyms, reasons for rejection ofan epithet are usually given; taxonomic synonymy is without comment. Table I summarizes the status of the Hawaiian moss flora.
