“…Geographic distribution data refers to the departments where the species were registered based on herbarium specimens and field observations, and is abbreviated as follows: Artigas: AR; Canelones: CA; Cerro Largo: CL; Colonia: CO; Durazno: DU; Flores: FS; Florida: FA; Lavalleja: LA; Maldonado: MA; Montevideo: MO; Pay: PA; Río Negro: RN; Rivera: RI; Rocha: RO; Salto: SA; San José: SJ; Soriano: SO; Tacuarembó: TA, and Treinta y Tres: TT. Additionally, the distribution in neighboring regions of Uruguay was investigated in order to detect the southernmost limit for each species; for this purpose we consulted several online databases (GBIF 2018; SPLink 2018; Flora do Brasil 2020 2019; IBODA 2019), publications concerning vascular epiphytes (Bauer & Waechter 2011;Perleberg et al 2013;Carneiro et al 2016;Gonzatti et al 2016;Machado et al 2016;Martínez et al 2016;Guerrero & Cellini 2017;Pellegrini 2018), and in some cases data from herbarium labels. Habitat distribution follows the forest classification previously described (see Study area).…”

“…Observation: we include P. filicula in the epiphytic flora of Uruguay because within its natural range and in neighboring areas of Uruguay it grows as holoepiphyte (Evans 1969;Márquez et al 2006;Cervi & Borgo 2007;Torres et al 2013;Martínez et al 2016). However, only two exsiccates of this species exists in the country (MVM 4195 and MVFA 27662), of which one of them (MVM 4195) is ancient and lacks collection data (date, environment and locality); therefore, information about this species is limited.…”

Catalogue of the vascular epiphytic flora of Uruguay

We provide an updated list of the vascular epiphytic flora occurring in native environments of Uruguay based on literature review, herbarium specimens, and fieldwork throughout the country. The catalogue provides standardized information for each species, including accepted name, synonyms used within Uruguay, epiphytic category, distribution within the country, habitat, conservation status, observations, and a voucher citation. The effort documented 73 species for the epiphytic flora of Uruguay (3 % of the flora), distributed among 29 genera and 12 families. Bromeliaceae was the richest family (17), followed by Polypodiaceae (16) and Orchidaceae (12). Tillandsia stood out as the most speciose genus with 15 species. Characteristic holoepiphytes was the most diverse ecological category. More than half of the epiphytic species documented for Uruguay (53 %) reach their southernmost geographic distribution in the country, whereas only two mostly epipetric species of Tillandsia-T. arequitae and T. uruguayensis-are endemic to the country. Almost half of the epiphytic species found are presently under categories of threat of extinction, with 60 % of them occurring in national protected areas. Both the richest epiphytic families and the predominance of characteristic holoepiphytes coincide with findings from floristic and ecological studies previously carried out in humid subtropical regions.

Eryngium L. comprises ca. 250 species and is distributed in every continent, except Antarctica. The species of the genus that inhabit Chile are mostly endemic to that country and are phylogenetically closely related to species from the west coast of the United States of America and Australia. Taxonomic studies of the North American and Australian lineages of Eryngium are in press or in preparation. However, the Eryngium species from Chile have not been revised taxonomically for more than a century. Moreover, many of the species of the genus endemic to Chile show restricted distributions and, therefore, deserve particular attention to evaluate if they are in any category of threat in order to develop conservation policies. The objective of this study is to perform a taxonomic revision of the species of Eryngium from Chile, including an analysis of their conservation status. For this purpose, the vegetative and reproductive morphology and the geographic distribution and habitat of ca. 750 herbarium specimens were analyzed. In addition, the conservation status of the species was evaluated following the Red List categories and criteria of the International Union for Conservation of Nature. In total, 17 species of Eryngium were recognized in Chile, of which 15 are endemic to that country and two also grow in Argentina. A key for the recognition of species is provided. For each species, a list of accepted synonyms, a morphological description, illustration, distribution map, habitats, phenology, and vernacular names are presented. Six new synonyms are proposed (Eryngium polyrhizum Clos and all varieties of E. depressum Hook. & Arn. are synonymized with E. depressum, E. amethystinodes Kuntze is synonymized with E. rostratum Cav., and E. delarocheanum H. Wolff is synonymized with E. paniculatum Cav. & Dombey ex F. Delaroche), and nomenclature problems were analyzed and resolved, including the typification of 23 names. The distribution ranges of six species (Eryngium anomalum Hook. & Arn., E. coquimbanum Phil. ex Urb., E. depressum, E. humifusum Clos, E. pulchellum Phil., and E. rostratum) are rectified. Aproximately 60% of the Eryngium species from Chile belong to a category of threat, and most of them are critically endangered, so they should be special targets for conservation.

Os epífitos desempenham importantes funções ecológicas, e em particular as samambaias, mostram uma diversidade significativa em ambientes florestais, ocupando microambientes específicos e diversos. A diversidade de samambaias epifíticas no estado do Paraná ainda é relativamente pouco conhecida. A região de Paula Freitas, em particular, não apresenta estudos específicos para este grupo de plantas. Neste sentido, o presente estudo teve por finalidade avaliar a riqueza de espécies de samambaias epífitas em regiões de trilhas no Parque Municipal Guairacá em Paula Freitas, Paraná. Foram registradas 10 espécies distribuídas em oito gêneros e quatro famílias. A família Polypodiaceae foi a mais rica na área avaliada (oito espécies), reflexo das características morfoanatômicas comuns às espécies da família. Os resultados encontrados contribuem com o reconhecimento das características florísticas e ecológicas de samambaias epífitas ocorrentes no estado do Paraná
