Observations on Riccia sorocarpa Bisch. subsp. erythrophora R.M.Schust. ex Kons...

Recent bryological research in Portugal has revealed the occurrence of a little-known segregate of the Riccia sorocarpa group, representing the first record for mainland Portugal and the Azores of Riccia sorocarpa Bisch. subsp. erythrophora R.M.Schust. ex Konstant. & L.Söderstr. New data are presented on the taxonomy and phytogeography of this globally rare taxon. A revision of approximately 200 samples of Ricc...

Contributions to the design of mobile applications for visitors of Botanical Ga...

Botanical Gardens are among the most visited touristic attractions, offering scientific, educational, cultural and leisure activities to preserve and enhance heritage and disseminating specialised knowledge on science and history. There are several mobile applications (apps) to support visitors of Botanical Gardens, which explore augmented reality technologies to enrich their experience. Our work aims to system...

Global geographical range and population size of the habitat specialist Codonob...

Introduction. Codonoblepharon forsteri (Dicks.) Goffinet is a rare epiphytic moss characteristically associated with water-filled holes in trees. We reviewed its range and population and assessed effects of climate change. Methods. An inventory of sites from where Codonoblepharon forsteri has been recorded was compiled. Extent of occurrence (EOO) and area of occupancy (AOO) were calculated. Population size was ...

Observations on the Taxonomy and Distribution of Epipterygium atlanticum Hanusc...

Epipterygium atlanticum Hanusch is a recently described species based on plants occurring mainly in Macaronesia, with one collection from Scotland. Against this background, we studied 144 specimens of E. tozeri s.l. in LISU herbarium from mainland Portugal, including recent field collections, and 70 were referable to E. atlanticum. The length and width of mid-leaf laminal cells of lateral leaves were the most i...

A contribution to the knowledge of the bryophytes of the Cape Verde Islands, wi...

Introduction. The Cape Verdean bryophyte flora comprises representatives of various floristic elements including Afrotropical, Neotropical, Mediterranean and Asiatic elements, together with some endemic taxa. However, the knowledge of Cape Verdean bryophytes lags far behind that of vascular plants. This study contributes to increase the knowledge of bryophytes in the Cape Verde archipelagos. Methods. A total of...

On the Synonymization of Acaulon longifolium Herrnst. & Heyn with Acaulon fonti...

During bryological work conducted in the Sharon plane region (Israel), a colony of Acaulon Müll. Hal. was discovered. The plants showed morphological affinities both to A. longifolium Herrnst. & Heyn and A. fontiquerianum Casas & Sérgio depending on the floras used for their identification which challenged their recognition as separate species. In order to solve this taxonomic dilemma, we conducted a detailed m...

Dimorphic Sexual Expression and Anisospory in Homalothecium sericeum Schimp. s....

Among terrestrial plant species, male dwarfi sm (nannandry) is a unique feature of bryophytes, common in numerous dioicous pleurocarpous mosses. In this study, our objective was to describe and to elucidate the incidence of dwarf males in Portuguese populations of Homalothecium sericeum (Hedw.) Schimp and H. meridionale (M. Fleisch. & Warnst.) Hedenäs.We also evaluated the occurrence of sporophytes and of dwarf...
