Bryophyte collection of Porto Herbarium (PO)
The Porto Herbarium (PO) contains about 22 000 herbarium specimens of bryophytes (including mosses, liverworts and hornworts), collected since 1837 by 61 different collectors, which have been actively databased in the last years. The majority of specimens were collected in Portugal, but PO Herbarium also includes a collection (General Herbarium) with specimens from many European countries and the former African colonies (Mozambique, Angola, São Tomé e Príncipe). In this dataset are represented 7621 records corresponding to three independent collections. Among the most relevant collections, we highlight the historical collection of António Machado, who published the first Portuguese Bryophyte Flora (1925-1933) and is a European reference collection with type specimens. The bryophyte collection of António Machado holds 1591 records collected all over Portugal but mainly in the northwestern part, corresponding to 3 phylum (Bryophyta, Anthocerotophyta and Marchantiophyta), 174 different genus and 401 taxa (species, subspecies and varieties), being the main collector António Luís Machado Guimarães. The two other collections included in this dataset correspond to more recent collections done in specific habitats (watercourses and exposed rock outcrops) during floristic and ecological surveys between 2002 and 2007. The watercourses dataset corresponds to a field survey carried out by the collector Cristiana Vieira in Portuguese Northwest mainland and Sicó mountain regions, located in the transition zone between Atlantic and Mediterranean territories. This watercourse dataset is substantially composed of saxicolous aquatic and semi-aquatic taxa, with 3033 records with a predominance of mosses (119 taxa of mosses, 38 taxa of liverworts and 1 taxon of hornworts). The exposed rock outcrops dataset corresponds to a field survey carried out by the collector Helena Hespanhol in North and Central Portugal region. In this dataset are represented 2997 records corresponding to 2 phylum (Bryophyta and Marchantiophyta), 74 genera and 128 taxa (species, subspecies and varieties) found on rock surfaces, fissures and cavities.
