Several new synonyms are recognized for Colombian taxa: Aongstroemia maculata = A. julacea, Callicostella acutifolia and C. plicatula = Thamniopsis diffusa, Dicranella mayorii and D. peruviana = D. hilariana, Glyphomitrium lobuliferum = Ptychomitrium lindigii, Trichostomum novo-granatense = T. brachydontium; and for Ecuadorean taxa: Grimmia cinerea = G. longirostris, Grimmia benoistii = G. trichophylla, Neckera benoistii = N. chilensis, Orthostichopsis incertus = Porotrichendron superbum, and Renauldia obovata = Neckera obtusifolius. Additional Colombian synonyms recognized by specialists are listed.
A survey of the bryophyte flora of Rio Branco Municipality, State of Acre, Brazil, has revealed a total of 76 species of bryophyte; 66 are new records for the State of Acre and two hepaticas, Cololejeunea dzumacensis P. Tix. and Lejeunea bermudiana (Evs.) Schust., are new records for Brazil. The Anthocerotae are represented only by Notothylas vitalii Udar & Singh.
No bryophyte conservation programs are in place in Australia as the knowledge of bryophytes is poor, especially of their habitat preferences and distribution. The conservation of species against habitats is discussed and it is maintained on present evidence that areas conserved for vascular plants and/or animal habitats, as national parks and forest reserves, in most cases would adequately conserve bryophytes.
Se describen e ilustran las dos especies de Cololejeunea (Lejeuneaceae subfam. Cololejeuneoideae) halladas en Misiones. C. minutissima subsp. myriocarpa (Nees & Mont.) Schust. es citada por primera vez para las provincias de Misiones, Formosa y Corrientes en Argentina y para Paraguay; se proponen como nuevos sinónimos de esta subespecie: C. spegazzinii (C. Mass.) C. Mass., Lejeunea myriandroecia Spruce y C. myriantha (Herz.) S. Arnell. C. cardiocarpa (Mont.) Evans es citada por primera vez para Argentina (provincias de Misiones, Corrientes y Buenos Aires) y Paraguay.
The group of Romalina cochlearis Zahlbr. and its allies in tropical America have been revised. Romalina cochlearis is reported from four countries: México, Honduras, Colombia and Venezuela. Romalina escorialensis and R. vareschii, both from Venezuelan Andes, and R. xalapensis from México are described as new. A key and descriptions are provided.
Romalina subfraxinea Nyl. Var. Confirmata (Nyl.) N. Stevens ist reported as new to the New World from the Venezuelan Andes. Thus far this variety was knowm only from Australia, New Caledonia and Indian Ocean. It has cryptochlorophaeic acid as chemical compound. Comments about ecology and morphology are given.
Anläßlich der Untersuchung der Vegetation westafrikanischer Inselberge in der Republik Elfenbeinküste, in Senegal und in Guinea wurden auch Moose gesammelt. Ihre Bestimmung ergab 43 Neunachweise für diese Länder, die zu den floristisch am wenigsten bekannten tropischen Länder gehören. Es handelt sich überwiegend um Arten mit sehr weiten Arealen. Es wird angenommen, daß Inselbergstandorte aufgrund ihrer besonderen ökologischen Bedingungen eine Standortskonstanz über lange Zeit und auch in wechselnden Klimaperioden geboten haben. An solchen Refugien konnten trockenadaptierte Sippen in feuchteren Klimaperioden überdauern und sich in trockeneren Klimaperioden wieder auf Savannen ausdehnen. Die Neukombination Archidium globiferum (Brid.) Frahm (Pleuridium globiferum Brid.) wird für Archidium ohioense Schimp. ex C. Müll., eingeführt.
The treatment of non epiphyllous Lejeuneaceae taxa was published in the first part of the Central African BRYOTROP results (Pócs 1993b). Anyhow, a nice material collected on tiny twigs (partly from fallen canopy branches) from the W edge of Nyungwe Forest Reserve, in a wet type of montane rainforest at 2000 m altitude, remained unidentified.
