New records, names and combinations of scaly tree ferns (Cyatheaceae) in eastern Malesia Naturalis
Coritico, F.P.; Amoroso, V.B.; Lehnert, M..
Several scaly tree ferns (Cyatheaceae) from eastern Malesia are transferred from Cyathea s.lat. to other genera: Alsophila roroka from Sulawesi; Alsophila lamoureuxii from New Guinea; Alsophila binayana, A. bisquamata, A. mapahuwensis, A. murkelensis, A. ohaensis, and Sphaeropteris pukuana from Seram. A new name is chosen for Cyathea coriacea, Alsophila katoi, which here is first reported for the Vogelkop Peninsula, New Guinea. Alsophila commutata, a tree fern with branched trunks, is first reported from the Philippines, expanding its original distribution from the Malay Peninsula, Sumatra, and Borneo. A detailed and revised diagnostic description of this species is provided and a second-step lectotype is chosen.
Tipo: Article / Letter to the editor Palavras-chave: Alsophila; Cyatheaceae; Mindanao; New Guinea; Philippines; Sulawesi; Threatened.

The scaly tree ferns (Cyatheaceae-Polypodiopsida) of Brazil Acta Botanica
Weigand,Anna; Lehnert,Marcus.
ABSTRACT A synopsis of all scaly tree fern species (Cyatheaceae) occurring in Brazil is presented. We recognize 51 species in three genera [Sphaeropteris one species, Alsophila four species (one subspecies, two varieties), and Cyathea 45 species (one variety) ] with 17 taxa being endemic to Brazil. One hybrid endemic to Brazil is recognized. Further included are five species that have not yet been recorded in Brazil, but are expected here because they are found in adjacent countries and occur literally on the border with Brazil. We present the first key covering the family for the whole territory of Brazil.

Environmental factors affect population structure of tree ferns in the Brazilian subtropical Atlantic Forest Acta Botanica
Schwartz,Carlos Eduardo; Gasper,André Luís de.
ABSTRACT Tree ferns are important elements of tropical forests, mainly because they are common and provide microhabitats for epiphytic plants. Due to their ecological importance, the aim of this study was to evaluate population structure, distribution, and influence of environmental variables on tree ferns in the state of Santa Catarina, southern Brazil. All tree ferns with a diameter at breast height ≥ 10 cm on 418 sampling units (SUs) systematically distributed throughout the study area were measured (total sampled area of ​​153.4 ha). Population structure was evaluated through classical phytosociological parameters and the relationships among dominance and environmental variables were evaluated through multiple linear regression models. Dicksonia...

La familia Cyatheaceae (Pteridophyta) en Argentina Boletín de la Sociedad
Marquez,Gonzalo J.
La familia Cyatheaceae comprende alrededor de 500 especies de helechos arborescentes. Su distribución es pantropical y en Argentina se encuentra representada por 4 especies, reunidas en los géneros Alsophila y Cyathea: A. setosa, A. odonelliana, C. atrovirens y C. delgadii. En este trabajo se presenta una actualización de la información disponible hasta el momento referente a estas especies. Se exponen microfotografías de las esporas, que presentan la superficie con lomos en Alsophila y con cordones en Cyathea. Se ilustran los indusios y escamas de la base de los pecíolos, que son de importancia fundamental para la diferenciación de las especies estudiadas. Asimismo se presenta un mapa de distribución y una clave de las especies que crecen en Argentina.
