Bryophyte flora of the Huon Peninsula, Papua New Guinea. LXVI. Meesiaceae (Musci), with lists of boreal to temperate disjunct, bipolar, and widely spread species in New Guinea

Meesia triquetra (Richter) Angstr. is the only species of the family Meesia ceae occurring in Western Melanesia and New Guinea. Two collections are fro m high elevation wetland areas, where the plant presumably has a similar ha bitat ecology on wet soils as in its northern localities. Documented list o f boreal to temperate northern hemisphere bryophyte species having disjunct occurrences in New Guinea, list of bipolar species, and list of widely dis tributed species are presented. Most of disjunct species and bipolar specie s are either plants of high elevation open and rocky habitats or wetland ha bitats such as shore meadows or bogs in New Guinea. Widely distributed spec ies occur either in habitats created by man's activities, or are plants of open or shaded rocky habitats, preferably cliffs.
