<p><strong>Lentibulariaceae in the Atlantic Forest of Northeastern Brazil</strong></p>

Abstract

This study comprises the survey and taxonomic treatment of the Lentibulariaceae species occurring in the Atlantic Forest phytogeographic domain of Northeastern Brazil, including the states of Alagoas, Bahia, Ceará, Paraíba, Pernambuco, Rio Grande do Norte and Sergipe. Thirty-one species from the two genera Genlisea (3 species) and Utricularia (28 species) were confirmed, and 13 species were found to be wrongly reported for the study area. Four out of these 31 are new records to Sergipe, one to Bahia, one to Rio Grande do Norte, and one to Paraíba and Rio Grande do Norte; the latter one is also a new record for the Atlantic Forest. Only one species is endemic to the Atlantic Forest (Genlisea lobata) and only one to Northeastern Brazil (Utricularia flaccida), while 18 are widely distributed in the country, occurring in more than two phytogeographic domains. Other species present disjunct distributions that corroborate the already documented Atlantic-Amazonian and Atlantic-Cerrado connections. Here, an identification key, illustrations, photographs, distribution maps, besides taxonomic and phenological comments, are also presented. Moreover, an updated preliminary assessment of their conservation status at global scale, using IUCN Red List criteria, combined with a habitat preference categorization, is given as well.

Flora of Espírito Santo: Lentibulariaceae

“…1). This is a fairly common and widespread species, frequently found sympatric with other congeners (Guedes & Alves 2020). Some fairly common species with only one to three records for the state (U. hydrocarpa, U. myriocista, U. nephrophylla, U. reniformis, U. tridentata and U. triloba) reinforce the need for a greater collection effort in several areas of low-and highlands in the state, with similar phytophysiognomies and conditions prone to the occurrence of the family.…”

“…Thus, in this study, four species were considered new records for the state: U. hydrocarpa, U. pusilla, U. triloba and U. tridentata. The first three species are fairly common and widely distributed in the country (Guedes & Alves 2020). On the other hand, U. tridentata was only known from Argentina, Uruguay, and in Brazil from the states of Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Sul and Santa Catarina (Taylor 1989;.…”

“…Utricularia longifolia and U. tricolor are species that can be found in both high-and lowlands, in areas of Ombrophilous Forest, Seasonal Semideciduous Forest, campos rupestres and campos de altitude (Taylor 1989;Zappi et al 2003;Baleeiro et al 2017;Guedes & Alves 2020). Besides the Forno Grande State Park, U. tricolor also occur in restingas in the municipality of Guarapari (Fig.…”

“…1). Restingas are coastal plains with pioneer formations, which are seasonally flooded habitats that present great richness of Lentibulariaceae species, and share several representatives found in campos rupestres and veredas from the Cerrado domain (Guedes et al 2018;Guedes & Alves 2020). In Espírito Santo, these representatives are the widely distributed U. erectiflora, U. foliosa, U. gibba, U. hydrocarpa, U. myriocista, U. pusilla and U. subulata (Fig.…”

“…Like several other carnivorous plants, Lentibulariaceae are usually found in open, sunny, wet habitats with acidic and nutrient-poor soils, and Rodriguésia 73: e02182020. 2022 free of urban waste (Givnish et al 1984;Jennings & Rohr 2011;Cross et al 2020;Guedes & Alves 2020). The family includes species with different growth forms, ranging from terrestrials, lithophytes (rupicolous), helophytes (amphibians) to epiphytes, rheophytes (haptophytes), and hydrophytes (aquatic free-swimming) (Ellenberg & Mueller-Dumbois 1967;Taylor 1989;Cook 1996).…”
