| Summary: | During an early summer visit in 2000, mosses were collected from sites around Heard Island. Three species, Bryoerythrophyllum recurvirostrum (Hedw.) P.C.Chen, Philonotis cf. tenuis (Taylor) Reichardt and Syntrichia filaris (Mull. Hal) R.H. Zander have been added to the list of moss species known from the island, bringing the total to 40 moss taxa. Syntrichia anderssonii (Angstrom) R.H. Zander was found with sporophytes, whereas previously its sporophytes were known in the subantarctic only from Macquarie Island. Extensions of range on Heard Island have been recorded for several species. There are few geographical differences in species composition between locations around the island, provided appropriate habitats exist.
