Gertrudiella validinervis (Herz.)Broth. (Pottiaceae, Musci) is new record for the bryological flora of Argentina. Gertrudiella validinervis (Herz.) Broth. are plants with strong central strand and hyalodermis present in the stem; acute leaves with base sheathing, costa with one stereid band and a multilayered cylinder of thick-walled guide cells. Laminal cells are medially bulging ventrally and flat dorsally but marginally bulging on both sides in several rows. This monotypic genus is registered for the first time for Argentina. The original description is completed with sporophytic characters.
Records on the distribution of Ptychanthoideae (subfam. of Lejeuneaceae, Hepaticae) in Australia
(2003)
Three species are new for the Northern Territory of Australia: Acrolejeunea securifolia (Nees) Steph. ex Watts ssp. securifolia, Archilejeunea planiuscula (Mitt.) Steph. and Mastigolejeunea ligulata (Lehm. & Lindenb.) Schiffn., and one for Queensland: Thysananthus australis (Steph.) B. Thiers & Gradst. New records of species are given, which were previously known only from one or very few localities, including: Caudalejeunea cristiloba (Steph.) Gradst. and Lopholejeunea plicatiscypha (Taylor) Steph.
De la Serranía del Perijá (Cesar-Colombia), a lo largo del gradiente altitudinal se describen cinco comunidades de briófitos (dos en las franjas subandina baja – tropical y tres en las franjas subandina baja-alta) cuyas características dependen de factores como el clima (humedad e intensidad lumínica), la estructura y la composición de la vegetación superior. Los análisis se realizaron siguiendo los lineamientos de la escuela Braun-Blanquetiana y la aplicación del Twinspan. Además, se analizan sus formas de crecimiento en todas las franjas altitudinales, las más comunes son felpas lisas, felpas rugosas e hilos.
12 hepatics and 32 mosses are reported new to Uganda, 1 moss being also new to Africa, and 1 liverwort new to mainland Africa. Ectropothecium plumigerum (Broth.) Hedenäs is a new combination (basionym: Isopterygium plumigerum Broth.) with a new synonym Taxicaulis plumirameus Müll.Hal. nom. nud., and Taxiphyllum maniae (Renauld & Paris) M. Fleisch. is a new synonym of Taxiphyllum taxirameum (Mitt.) M.Fleisch. Three mosses are removed from the Uganda list.
The nine species and two varieties of Schoenobryum reported for Africa were investigated, and no characters were found that uniquely identified any of the taxa to be other than the pantropical Schoenobryum concavifolium. The following nine names become new synonyms of S. concavifolium: Cryphaea madagassa, C. subintegra, Acrocryphaea robusta, A. latifolia, A. subrobusta, A. tisserantii, A. latifolia var. microspora, A. plicatula and A. subintegra var. idanreense; a lectotype is selected for Acrocryphaea latifolia var. microspora P.de la Varde.
Gammiella ceylonensis (Broth. in Herzog) W.R.Buck & B.C.Tan is the only species of the genus in Africa. Clastobryella pusilla (Thér.) Wijk & Margad., recorded from Madagascar, the only member of the genus still recorded on the moss checklist for Africa, is a synonym of Gammiella ceylonensis. Clastobryella foliicola P.de la Varde is not a synonym of Gammiella ceylonensis but probably an Ectropothecium, thus removing the only west African record for Gammiella. An extension of range into South Africa is also noted, so Gammiella is now known from east and southern Africa and Madagascar.
A new species, Cephaloziella biokoensis Vá a & F.Müller, is described and illustrated. The type locality is at the highest point of the island of Bioko (Equatorial Guinea) at an altitude of ca. 2900 m NN. The new species belongs to subgenus Prionolobus (Spruce) Müll.Frib. and is closely related to C. turneri (Hook.) Müll.Frib. The main differences between these two species are shown in a table.
Collections of mosses have been made from the 911 metre high Gunung (Mount) Serapi in Sarawak. A total of 77 species in 37 genera within 17 families were discovered and are enumerated below. Five species are reported for the first time for Borneo: Aerobryidium aureonitens (Hook. ex Schwägr.)Broth., Distichophyllum schmidtii Broth., Mitthyridium fasciculatum subsp obtusifolium (Lindb.) M.Menzel, Papillidiopsis complanata (Dixon) W.R.Buck & B.C.Tan and Trichosteleum stigmosum Mitt. Seventeen species are new records for Sarawak. One family, Bartramiaceae, and 3 genera, Aerobryidium, Leucoloma, Philonotis, are new to Sarawak. The largest family is Calymperaceae, with 6 genera and 21 species, followed by Sematophyllaceae, with 10 genera and 19 species.
The moss flora of Argentina contains 990 species, 5 subspecies and 56 accepted varieties in 264 genera, plus 1 species and 13 varieties which are only tentatively accepted. The checklist includes legitimate accepted taxa with primary references and distributional data for Argentine provinces. All entries to the list are based on literature records. Additionally, the recognized taxonomic and nomenclatural synonyms are given in a separate alphabetical list. An extensive bibliography is given to vouch for occurrence of the plants and a map helps in the location of provincial distributions.
