The mosses of Easter Island

  • The bryophyte flora of Easter Island has been poorly known primarily because few botanists have collected there. In order to increase the knowledge of the flora the two authors collected bryophytes from 12 localities on the island from April 28-May 3, 2000. The small island, which is south of the Tropic of Capricorn, is of volcanic origin and the volcanic soil as well as the destruction of most of the native flora have undoubtedly contributed to the paucity of bryophytes. The present study revealed that the bryophyte flora consists of only a few species, including one unidentifiable member of the Anthocerotaceae, 11 hepatics and 30 mosses. Eighteen mosses are new to the island. Three mosses, Chenia leptophylla (Müll. Hal.) R. H. Zander, Dicranella hawaiica (Müll. Hal.) Broth. and Tortella humilis (Hedw.) Jennings, are new for Chile, while three, Fissidens pascuanus Broth. in Skottsb., Ptychomitrium subcylindricum Thér. and Trematodon pascuanus Thér., are presently known to be endemic to Easter Island. Two of the three endemics, Fissidens pascuanus and Ptychomitrium subcylindricum, were rediscovered on the island. Fissidens pascuanus was found with sporophytes for the first time and a revised description of the species is provided.
