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

Abstract

Aiming to increase the knowledge concerning the canga vegetation of the Serra dos Carajás, a taxonomic treatment of the Piperaceae species was prepared. Thirty species were recorded for the region, of which 20 taxa were found growing on canga substrate (ferruginous rupicolous vegetation). The majority of the species studied belong to Piper (23 species). The first record of P. goeldii for the state of Pará is presented, while the fruit of P. pellitum is described for the first time. Two out of seven Peperomia species studied - P. albopilosa and P. pseudoserratirhachis are described as new. Identification keys, detailed descriptions, geographical distribution and comments for taxa, besides illustrations of those poorly known or that are reported for the first time in the region, are provided.

Piperaceae do nordeste brasileiro II: estado de Alagoas

“…Piper hoffmannseggianum ocorre apenas no Brasil, sendo encontrado no Acre, Pará, Rondônia, Mato Grosso, Bahia, Distrito Federal, em todos os estados da região Sudeste e no Paraná (Flora do Brasil 2020 em construção), que pode ser considerado seu limite austral. Distingui-se pelas folhas oblongo-elípticas submarginalmente hirtela na face abaxial, espigas eretas com bráctea floral sacado-galeada e frutos oblongos, 4-angulosos, subturbinados e agudos no ápice, com quatro estigmas sésseis, como ilustrado em Monteiro (2018). A ocorrência desta espécie é aqui pela primeira vez apontada para o estado de Alagoas, onde foi coletada até o momento apenas uma vez, em área de mata.…”

“…Peperomia Ruiz & Pav on is the second largest genus of Piperaceae and one of the most species-rich genera of seed plants (Frodin 2004). The Neotropical Region harbors its largest species diversity , Mathieu 2001-2018, it comprising 1473 species and an additional 175 varieties and forms (Mathieu 2001(Mathieu -2018. In Brazil, the genus includes 173 species and 31 varieties, of which 108 are endemics (Flora do Brasil 2020).…”

“…In the last years, several new records and new species have been brought to our knowledge, based on recent Brazilian collections (e.g. Carvalho-Silva and Guimarães, 2008, Carvalho-Silva et al, 2013, Sarnaglia Junior et al, 2015, Monteiro et al 2016, Dantas et al, 2017, Marcusso et al, 2018, Monteiro, 2018.
