Madrono, Vol. 48, No. 1, pp. 1-16, 2001 A CATALOGUE OF MOSSES FOR THE CITY AND COUNTY OF SAN FRANCISCO, CALIFORNIA James R. Shevock and David Toren Department of Botany, California Academy of Sciences Golden Gate Park, San Francisco, CA 941 18-4599 Abstract The moss component for the bryoflora for the City and County ofSan Francisco contains 128 species representing over 22 percent of the California moss flora. Several mosses are suspected as being intro- duced since the mid-1900s and have subsequently becomeestablished and naturalized. A largecomponent ofthe moss floraofSan Franciscorepresentscosmopolitan specieshavingwidegeographicaldistributions. All but twelve ofthe 42 species based on the historic Bolander moss collections attributed to San Fran- cisco from the 1860s were relocated during this study. Sixty-five mosses are reported for the first time from the City and County of San Francisco. Of these, the rare species Triquetrella califoniica (Lesq.) Grout is also documented for San Francisco. Bryum pyriferum Crundw. & H. Whiteh., Campylopus pyriformis (F. Schultz) Bridel, Heterocladium dimorphiim (Brid.) Schimp. in B.S.G., Sematophyllum ad- natum (Michaux) Britton and Zygodon menziesii (Schwaegr.) Arnott are reported new for California and Zygodon menziesii is reported new for North America.
