The identity of Utricularia trinervia (Lentibulariaceae): Taxonomic re‐establishment and unpublished descriptions of trap morphology

Abstract

Previous morphometric and molecular studies indicate that Utricularia amethystina is a species complex distributed in the warmer zones of the Neotropical region. It includes 31 names accepted as synonyms, mainly based on morphological characteristics of bracts and bracteoles, traps and capsule dehiscence. Despite previous efforts and evidence suggesting that at least four names should be reconsidered at species level, this taxonomic complex still needs improved resolution and recircumscription for each species. Therefore, this contribution presents macro‐ and micromorphological evidence for the re‐establishment of U. trinervia, including its detailed taxonomic description, unprecedented characterization of its traps, habitat and distribution, conservation status and comparative discussion with U. amethystina s.str.

First record of Utricularia breviscapa C.Wright ex Griseb. (Lentibulariaceae) in Rio de Janeiro state, Brazil

“…Inflorescences are emergent in aquatic and amphibious species, and the flowers are bilabiate with a spur (Taylor 1989). The genus comprises approximately 240 species in tropical and subtropical regions (Guedes et al 2021). In Brazil, 71 species are distributed in all biomes, but only 20 are currently recorded from the state of Rio de Janeiro; two of them are endemic .…”
