A survey of the epixylic bryoflora of a remaining Atlantic forest (seasonal coastal deciduous forest), Engenho Água Azul, in the municipality of Timbaúba ( Lat 7° 35S; Long. 35° 20W ), State of Pernambuco, Brazil, registered 35 species of bryophytes distributed in 11 families of Bryopsida: Calymperaceae, Pilotrichaceae, Fissidentaceae, Hookeriaceae, Hypnaceae, Leucobryaceae, Leucomiaceae, Orthotrichaceae, Plagiotheciaceae, Sematophyllaceae, Thuidiaceae, and 5 of Hepaticopsida: Aneuraceae, Frullaniaceae, Geocalycaceae, Plagiochilaceae and Radulaceae. New records northeastern of Brazil are: Frullania caroliniana Sullivant, F. gymnotis Nees & Mont., Ochrobryum stenophyllum Besch., Plagiochila trigonifolia Steph., Radula macrostachya Linbenb. & Gott., Riccardia digitiloba (Spruce ex Steph.) Hell, Thuidium tomentosum Schimp. ex Besch. and Trichosteleum pusillum (Hornsch.) Jaeg. There is an indication of the description, illustration, and geographic distribution for Brazil of all taxons found.
A list of Pottiaceae specimens is presented. Trichostomum bombayense C.Müll. is transferred to the genus Pseudosymblepharis Broth., and a new combination is made: Pseudosymblepharis bombayensis (C.Müll.) P. Sollman. Five new synonyms are proposed. Gametophyte characters, separating non-fruiting material of Pseudosymblepharis bombayensis from Trichostomum tenuirostre (Hook. & Tayl.) Lindb., are listed.
Pleuridium andinum Herz., a rare moss previously known from only 3 sites in South America, is here reported from a second locality in Peru. The new locality is near Aquas Caliente, Peru, ca. 5720 m a.s.l. This discovery is only one of three collections made since this species was first collected at the “locus classicus” in Bolivia in 1911. The holotype was examined and the original Latin diagnosis is amended in English as a result of examination of both the holotype and the newly discovered specimens. Previously unknown taxonomic features are figured.
In the genus Rhizomnium T. Kop. most taxa have a strong leaf border several cells broad and bi- to tristratose. Rhizomnium striatulum (Mitt.) T. Kop. belongs to that group. In Northeast China one population of R. striatulum was found with a very weak leaf border, and also the costa of these plants is weaker than is characteristic for the species. The deviating population is figured and its significance discussed. The distribution of R. striatulum is mapped.
57 species of bryophytes belonging to 30 families are reported from Saiwa Swamp National Park, of which 57 species are new for Saiwa Swamp National Park and 10 records are new for Kenya, indicated by * and ** respectively. Although small in surface area (15.5 sq.km.) the park represents an undercollected area in Kenya with a good diversity of bryophytes.
Aldabra Atoll, in the Republic of Seychelles, lies 450 km to the north of Madagascar and 650 km to the east of the Tanzanian coast of Africa (9o24’S, 46o20’E). It is one of the largest atolls in the world, with four main islands and numerous islets, totalling 97 km2. The underlying limestone is slightly raised, but is generally less than 8 m in elevation, and varies substantially in texture due to erosion. The atoll has been elevated above sea level for at least 80,000 years. Soils are generally shallow and alkaline (Trudgill 1979). The geology and ecology are outlined in Westoll and Stoddart (1971), Stoddart and Westoll (1979), and Stoddart (1984).
Die 15 bisher in der Gattung Conostomum eingeschlossenen Arten werden auf 7 reduziert. Conostomum aequinoctiale Schimp. ex C.Müll., C. lorentzii C. Müll., C. pentastichum (Brid.) Lindb., C. pusillum Hook. f. et Wils. und C. speirostichum C. Müll. sind synonym mit C. tetragonum,(Hedw.) Lindb. Conostomum giganteum Bartr. ist nicht mit C. pentastichum identisch, sondern eine gute Art, die bislang nur von der Typuslokalität in Neuseeland bekannt war und jetzt neu für Australien und die Campbell Islands angegeben wird. Conostomum crassinervium P. Varde, eine nur vom Mt. Kenia bekannte Art, besitzt nicht die für die Gattung typische 5reihige Beblätterung. Da die Art nur steril bekannt ist, ist ihre systematische Position nicht klar.
