Abstract

Kürschner, H.: Nineteen new records to the bryophyte flora of Socotra Island. Additions to the Bryophyte Flora of the Arabian Peninsula and Socotra 5. — Willdenowia 33: 445–458. — ISSN 0511-9618; © 2003 BGBM Berlin-Dahlem.Based on recent bryophyte collections 19 new records are added to the bryophyte flora of the island of Socotra (Hadhramout governorate, Yemen), increasing the hitherto known number of species to 74 (one hornwort, 30 liverworts, 43 mosses). Outstanding among the new finds are the xerotropical, palaeo-African liverworts Frullania schimperi (Frullaniaceae), Radula comorensis (Radulaceae), Riccia argenteolimbata (Ricciaceae), as well as the pantropical moss Braunia secunda (Hedwigiaceae), which are shortly described and illustrated. In addition, one hornwort, Anthoceros punctatus, and the family Grimmiaceae (Grimmia laevigata, G. longirostris, G. trichophylla) are reported for the first time from the Socotra archipelago. Finally, an updated checklist for Socotra is given, including all accepted names and synonyms from the literature applied to Socotra.
