Piperaceae do Parque Nacional do Viruá, Caracaraí, Roraima, Brasil

Abstract

ResumoPiperaceae possui cinco gêneros, aproximadamente 3.600 espécies com distribuição pantropical, e no Brasil a família está representada por cerca de 450 táxons. Portanto, o objetivo desta pesquisa foi realizar o estudo taxonômico das espécies que ocorrem no Parque Nacional do Viruá, estado de Roraima. AbstractPiperaceae comprises five genera, approximately 3.600 species with a pantropical distribution, and in Brazil this family is represented by about 450 taxa. Therefore, the aim of this research was do the taxonomic treatment of species that occur in Parque Nacional do Viruá, state of Roraima. Field trips were conducted between September 2011 and August 2012, and vouchers from herbaria were also analyzed. We found 16 taxa, 12 of the genus Piper L. and four of Peperomia Ruiz & Pav. Eleven taxa are new records for the state, and one is a new record for Brazil. Most species were collected in the lowlands forests, but some were found in floodplain forests.

Brief Review on Piper aduncum L., its Bioactive Metabolites and its Potential to Develop Bioproducts

“…Piper genus constitutes one major class of medicinal plants used to manage pain and inflammatory disorders in folkloric practice and all genera are represented in the neotropical region, except the monotypic genus Zippelia, which is found in tropical Asia. In Brazil, Piperaceae is represented by about 450 taxa distributed in three genera; most are in both Atlântica and Amazon Forests, where approximately 280 and 230 taxa, respectively, can be found [14]. Its representatives may be epiphyte, terrestrial or rupicolous herbs, hemiepiphyte, vines, erect or scandent shrubs or small trees.…”

Flora of the canga of the Serra dos Carajás, Pará, Brazil: Piperaceae

“…Piper demeraranum, illustrated in relatively recent studies (Steyermark 1984;Steyermark & Callejas 2003;Melo et al 2014), is characterized by the presence of pilose-pubescent trichomes in the branches and veins of the abaxial surface of the leaves, erect or retrorse in the branches, with oblong to elliptic-obovate leaves, asymmetrically cordate-auriculate at base, erect spikes with floral bract narrow-lunate to triangular, slightly winged and by oblong, densely pilose-puberulent fruits. It occurs in the Guianas, Venezuela (Steyermark & Callejas 2003), Colombia (Lleras & Cruz 2005), Ecuador (Callejas & Burger 1999), Peru (Brako et al 2003), Bolivia (Callejas et al 2015) and Brazil, in Acre, Amazonas, Pará, Rondônia, Roraima and Mato Grosso states (Flora do Brasil 2020).…”

“…The spikes have been described as erect, with 0.5-2.7 cm long and 0.2-0.6 cm thick, sustained by a peduncle up to 1 cm long, pubescent; the rachis are glabrous, the floral bract triangular, subpeltate, equally short-fringed throughout the margin and the fruits are glabrous, globoseellipsoidal, ca. 2 mm long, slightly pointed at apex and with 3 sessile stigmas (Yuncker 1973;Melo et al 2014). It occurs only in Brazil, in the states of Amazonas and Roraima (Flora do Brasil 2020), to where the distribution was recently expanded by Melo et al (2014).…”

It occurs only in Brazil, in the states of Amazonas and Roraima (Flora do Brasil 2020), to where the distribution was recently expanded by Melo et al (2014). The specimen from the Serra dos Carajás is the first record for Pará state, and was collected in the 1980s, in hilly transition forest.…”

Synopsis of the genus Peperomia Ruiz & Pav. (Piperaceae) in Roraima State, Brazil

“…It occurs from Mexico to South America (Steyermark & Callejas-Posada 2003), and in Brazil is present in the Atlantic and Amazon Forests, in the States of Roraima, Amazonas, Pará and Acre (Melo et al 2014, Guimarães et al 2015. In the study area, it was found in lowland, montane and alluvial (várzea) forests.…”
