Threatened and uncommon bryophytes of New Zealand (2010 revision)

Abstract The threat status of New Zealands bryophytes (currently 13 hornwort species, 608 liverwort species and 520 moss species) has been re-evaluated, using revised New Zealand Threat Classification System criteria. Threatened or uncommon status has been applied to 269 taxa (c. 24% of the total number of species) and to 25 entities that are either described but disputed or are undescribed. No taxa are known to be extinct. Forty-one taxa are listed as Threatened (26 Nationally Critical, 9 Nationally Endangered and 6 Nationally Vulnerable). One hundred and thirty-six taxa and entities are listed as At Risk, including 122 Naturally Uncommon, 2 Relict and 1 Declining, 8 Non-resident Native, and 3 Introduced and Naturalized. One hundred and thirty-five taxa and entities are Data Deficient.

Studies of Fissidens (Bryophyta: Musci) in New Zealand: F. strictus Hook.f. & Wils. and F. berteroi (Mont.) C. Muell., with a discussion of aquatic adaptations

Abstract Fissidens strictus and F. berteroi are two Southern Hemisphere aquatic mosses which are apparently rare in New Zealand, but known from widely scattered localities. They contrast in morphology, F. strictus being a typical rheophyte, with stiff compact shoots, while F. berteroi has the lax habit typical of a limnophyte. Their detailed morphology is described and illustrated, their known New Zealand distribution documented, and observations made on their ecology. Fissidens strictus is lectotypified.

Hypnobartlettia fontana is an environmental form of Cratoneuropsis relaxa (Bryophyta: Amblystegiaceae)

Abstract The aquatic moss Hypnobartlettia fontana Ochyra was described, and placed in its own family, the Hypnobartlettiaceae, based on material collected at Te Waikoropupuu (“Pupu Springs”), Takaka, Nelson, New Zealand. It is known only from the type locality. Based on morphological evidence, we conclude Hypnobartlettia fontana is an environmentally induced form of the very variable Cratoneuropsis relaxa (Hook.f. & Wilson) Broth, modified in its morphology by the unusual physical features of its habitat in Pupu Springs. Data from published molecular studies relevant to this conclusion, and which do not support it, are equivocal and confounded by incorrectly identified material.

Studies of Fissidens (Bryophyta: Musci): New taxa and new records for New Zealand

Abstract Two new taxa in the moss genus Fissidens are described from aquatic habitats in New Zealand: F. waiensis sp. nov. and F. rigidulus Hook.f. & Wilson var. pseudostrictus var. nov. Fissidens perangustus Broth., a species known previously only from Australia, is recognised in New Zealand, and a lectotype designated. The presence of F. bryoides Hedw. in New Zealand is confirmed, based on modern collections. Fissidens vario‐limbatus Allison and F. leptocladus Mull.Hal. ex Rodway var. cheesemanii Dixon are placed in the synonymy of F. leptocladus var. leptocladus; F. australiensis A.Jaeger is reduced to a variety of F. tenellus Hook.f. & Wils.; and the new combination F. tenellus var. leptochaete (Dusen) J.E.Beever & I.G. Stone is made.

Studies of Fissidens (Bryophyta: Musci) in New Zealand: A synopsis and key to taxa

Abstract A synoptic taxonomic treatment is provided for the 24 species and 9 varieties of the moss genus Fissidens currently recognised in New Zealand. A key to the taxa, based largely on gametophytic characters, references to illustrations of New Zealand material, and an index to epithets are presented.

Studies of Fissidens (Bryophyta: Musci) in New Zealand: F. taxifolius Hedw. and F. integerrimus Mitt.

Abstract Descriptions, illustrations, and New Zealand distribution maps are provided for two species of Fissidens recently found in New Zealand. Fissidens taxifolius Hedw., a species widespread in the Northern Hemisphere and known also from South America and Papua New Guinea, is common in modified habitats in the north of the North Island, and has been found in a few scattered localities further south. It is suggested that the species may be a recent introduction to New Zealand. Fissidens integerrimus Mitt., known previously from Australia, has been found in forest streams at two sites in the north of the North Island.

Mosses of the Kermadec Islands, northern New Zealand

Abstract A list of mosses, comprising 52 species from 23 families, is provided for the Kermadec Islands, northern New Zealand. Cyclodictyon blumeanum is recorded new to New Zealand. Hypnum trachypelma is placed in synonymy with Eurhynchium speciosum, and lectotypes are designated for the names Hypnum trachypelma and Neckera kermadecensis. The moss flora of the Kermadec Islands contributes a significant subtropical element to the New Zealand mainland flora.

Taxonomic notes on two New Zealand mosses: Bryobartlettia costata Buck (Fabroniaceae) and Calliergon laxirete Zant. et Bartlett (Amblystegiaceae)

Abstract Examination of type material of Bryobartlettia costata Buck and Calliergon laxirete Zant. et Bartlett, two moss species recently described from New Zealand, indicates that both should be synonymised with existing taxa: Bryobartlettia costata with Cryphaea tenella (Schwaegr.) Hornsch. ex C. Muell., and Calliergon laxirete with Bryum blandura Hook. f. et Wils.
