<strong><em>Myrcia</em> (Myrtaceae) in the state of Paraná, Brazil</strong>

Abstract

Myrtaceae is one of the largest families in number of species within the order Myrtales and one of the richest families in Brazil. Myrcia is the fourth largest genus of Myrtaceae, with approximately 770 species distributed from Central America and the Caribbean to southern South America. In Brazil Myrcia is represented by 397 species, of which 309 are endemic. In this study, we present the taxonomic treatment for all species of Myrcia that occur in Paraná state, Brazil. Analyses of herbarium specimens, online databases, and bibliography were performed. Fifty-three species of Myrcia occur in Paraná, distributed in all vegetation types. Twenty-three names were excluded from previous lists of species or listed as doubtful species. Neither of the recorded species is endemic to Paraná, but this state is the southern and northern limit of distribution of six and two species, respectively. We present an identification key, taxonomic descriptions, figures, maps, and comments on phenology, habitat, and morphology for each species.

Indicator species and characterization of the woody and herbaceous layer in an Atlantic Forest ecotone area at the Paraná portion of Serra do Mar

“…From the MOF indicative species, Araucaria angustifolia, Campomanesia xanthocarpa, Allophylus edulis, Casearia decandra; Myrcia hatschbachii, and Cinnamodendron dinisii are highlighted as preferential or dominant in MOF (Legrand & Klein 1977;Sleumer 1980;Roderjan et al 2002;Coelho 2022;Salazar et al 2020;Lannoy et al 2021).…”

“…Sapium glandulosum occurs throughout Brazil, including in MOF and DOF (Cordeiro & Esser 2022). Myrcia splendens occurs in all vegetation types of the State of Paraná (Lannoy et al 2021).…”

“…In addition to these, specimens from the BHCB, CGMS, EVB, FUEL, FURB, HCF, HUCS, HUEFS, HUEM, MBM, NY, SP, U, UB, UPCB, and UNOP herbaria. The samples were analyzed with the aid of a stereoscope, and precise identification reached consulting specific literature (Landrum 1981;Lannoy et al 2021;Lima et al 2011;Proença et al 2022b;Sobral 2003Sobral , 2011. The correct spelling of scientific names and the species authors were checked against the International Plant Names Index (IPNI 2021) and Proença et al (2022a).…”

“…The popular name of the species is: guamirim. Complementary bibliography: Fernandes et al (2020); Lannoy et al (2021). DC., Prodr.…”

“…There are few studies specifically related to the Myrtaceae in the state of Paraná, i.e: floristic studies by Soares-Silva (2000) in the Tibagi river basin, which encompasses Cerrado, Dense Ombrophilous Forest, and Mixed Ombrophilous Forest; Romagnolo & Souza (2004, for the floodplain of the upper Paraná River, with Semideciduous Seasonal Forest formation influenced by the tributaries of the upper Paraná River; Lima et al (2015) for Ilha do Mel, formed by Dense Ombrophilous Forest, restingas (sandy costal forests) and mangroves; Rocha (2018) for Parque Estadual de Vila Velha, composed of Cerrado and Mixed Ombrophilous Forest. Three other studies are restricted to specific genera, such as Lima et al (2011) of Campomanesia, Sobral (2011) of Eugenia, and Lannoy et al (2021) of Myrcia. However, for the western region of the state formed predominantly by Semideciduous Seasonal Forest, such as the Parque Nacional do Iguaçu (ParNa Iguaçu), there are no floristic studies of this family.…”
