THE FAMILY SELIGERIACEAE (BRYOPSIDA) IN JAPAN

Abstract

  Species of Seligeria were little known in Japan until recently. Index Muscorum Japonicorum (Iwatsuki and Noguchi, 1973) listed only two species of the genus. We have been much interested in these small, calciphilous mosses, and collected in many places in Japan. In this paper, we list 10 species (with one variety) of Seligeria, together with four species of Brachydontium and two species of Blindia of the family Seligeriaceae. Seligeria acutifolia Lindb. and S. patula (Lindb.) Broth. are newly added to the moss flora of Japan. The new combination, Brachydontium pseudodonnianum (Tad.Suzuki & Z.Iwats.) Tad.Suzuki & Z.Iwats. is made. Keys to the genera and species of the family are given. Descriptions and illustrations of newly added species, Seligeria acutifolia and S. patula and S. pusilla, which has been insufficiently understood in Japan, are given. Distribution maps of 16 species of the family are provided.
