Occurrence of the neotropical moss Dicranella hilariana (Mont.) Mitt. in the Antarctic

Dicranella hilariana (Mont.) Mitt., a pan-neotropical moss species, is reported for the first time from the Antarctic botanical zone. It was found on geothermally heated ground near fumaroles on Visokoi, Candlemas and Bellingshausen Islands in the volcanic archipelago of the South Sandwich Islands. Dicranella recurvata Ochyra, Arts & Lewis-Smith, nom. nud., is reduced to synonymy with D. hilariana. The Antarctic plants of D. hilariana are briefly described and illustrated, including the rhizoidal tubers which have not previously been reported in this species. The global distribution of D. hilariana is briefly reviewed and mapped. It is suggested that the species reached the Antarctic via long-distance dispersal from South America by the prevailing strong westerly winds

A new combination in Torrentaria (Brachytheciaceae, Bryophyta), with new records of T. muelleri in Australia

Rhynchostegium muelleri A.Jaeger is transferred to Torrentaria muelleri (A.Jaeger) Ochyra & Bednarek-Ochyra (Brachytheciaceae)

Dicranella hookeri (Dicranaceae, Bryophyta) in northern Argentina

Aongstroemia lorentzii Müll.Hal. from the central Andes of subtropical Argentina is taxonomically evaluated and some diagnostic traits of its type material are illustrated. This species is revealed to be inseparable from Dicranella hookeri (Müll.Hal.) Cardot, a pan-south-temperate species which extends into the Neotropics along the Andean chain. This discovery represents the first record of D. hookeri from northern Argentina and this locality bridges the continuous south-temperate range of the species, extending from Tierra del Fuego to central Chile, with its altimontane stations in Bolivia

A major range extension of Blindia robusta (Seligeriaceae, Bryophyta)

The endemic species Ditrichum tenuinerve Dixon from Tristan da Cunha is taxonomically evaluated and some details of its type material are illustrated. This species shares the diagnostic characters of Blindia robusta Hampe and the two species are considered to be conspecific. As a result of this taxonomic conclusion the global range of B. robusta is extended to the South Atlantic Ocean and accordingly it has to be considered as a nearly pan-south-temperate, not an amphipacific south-temperate species. The global distribution map for B. robusta is presented

Early taxonomic history of the moss genus Anacamptodon and a lectotype for A. splachnoides (Amblystegiaceae)

Early taxonomic history of the pleurocarpous moss genus Anacamptodon Brid. is reviewed and its familial placement is discussed. A specimen from the Bridel Herbarium (B-Bridel) is designated as the lectotype of Orthotrichum splachnoides Froel. ex Brid., the basionym of its generitype A. splachnoides (Froel. ex Brid.) Brid. It was collected in June or July 1811 by Josef Aloys von Frölich in Ellwangen (Jagst) in the historic, linguistic and cultural region of Swabia in the east of the state Baden-Württemberg in south-western Germany. He recognised it as a new species on the herbarium label and sent the material to S. E. Bridel in Gotha, Germany, then the great authority on moss taxonomy, who described it as a new species in his Muscologiae recentiorum supplementum seu Species muscorum Pars 2 in 1812. Duplicates of the original specimens of this species have been located in the Herbarium Tubingense (TUB) and in the Hedwig/Schwagrichen Herbarium (G) which are isolectotypes. Moreover, Frölich consulted the identity of this moss with Olof Swartz in Stockholm, Sweden, and four original specimens of A. splachnoides are present in his personal herbarium at S

A brief survey of bryological studies in the Subantarctic, including Macrocoma tenue (Orthotrichaceae), a moss genus and species newly found in Îles Kerguelen

Studies on the bryophyte flora of the Southern Ocean islands and in the Antarctic are briefly reviewed and the current state of knowledge of the moss flora of Îles Kerguelen is discussed. Macrocoma tenue (Hook. & Grev.) Vitt is recorded from the Îles Kerguelen archipelago and this constitutes the first record of the genus Macrocoma (Müll. Hal.) Grout from the Subantarctic. The local plants of the species are characterized and illustrated and their ecology is discussed. Global distribution of M. tenue is reviewed and mapped. It is suggested that the type subspecies of M. tenue is a Gondwanan relictual taxon, which could have evolved on this supercontinent prior to its break-up and, subsequently, it reached Îles Kerguelen where it survived during the Pleistocene glacial epoch

<I>Bucklandiella lamprocarpa</I> (Musci, Grimmiaceae) in the central and northern Andes

The current geographical distribution of the rheophytic moss Bucklandiella lamprocarpa (Müll.Hal.) Bednarek-Ochyra et Ochyra in the central and northern Andean countries in South America is reviewed and mapped. The specimens reported from Peru as Racomitrium bartramii (Roiv.) H.Rob. are taxonomically assessed and some details of their structure are illustrated. As a result of this study it was determined that its morphological features fall well within the range of variability of Bucklandiella lamprocarpa. The global geographical distribution of B. lamprocarpa is outlined and the species is confirmed to be an austral cool-adapted moss which deeply penetrates into the tropics, occurring at high elevations in central and northern South America and in East and Central Africa.</p
