Two New Species of Pouteria (Sapotaceae) from the Atlantic Forest in Brazil

Abstract

This paper provides descriptions and illustrations of two new species of Pouteria from the Atlantic forest of Bahia, Brazil (P. atlántica and P. trifida). In addition, distribution maps and a table with main characters to distinguish the new species from related taxa are also included. Pouteria atlántica is characterized by large trichomes that cover the corolla lobes, anther's outer surface, and form tufts on the apex of anthers. Pouteria trifida is distinguished by its long petioles and trifid staminodes. Due to intense deforestation in the Atlantic forest, preliminary IUCN red list assessments are provided. Pouteria atlántica is proposed in the IUCN status critically endangered (CR), while the data for P. trifida are still insufficient.

Species tree phylogeny and biogeography of the Neotropical genus Pradosia (Sapotaceae, Chrysophylloideae)

“…Species are distributed across a wide variety of habitats, including savannahs and evergreen to deciduous forests in the Amazon region, the Brazilian Atlantic coast, and the Andes. The Amazon and Atlantic coast are the two major centres of diversity for Sapotaceae (Pennington, 1990;Alves-Araújo and Alves, 2011;Terra-Araujo et al, 2013), where 80% of the species occur. The biogeographical connections between these regions are still poorly understood and, to date, only a handful of studies have estimated divergence times between taxa from these regions, finding that organisms in the two areas have been isolated from each other for several million years (Vicentini, 2007;Fiaschi and Pirani, 2009;Pellegrino et al, 2011;Fouquet et al, 2012a,b).…”

First record of Pouteria franciscana Baehni (Chrysophylloideae, Sapotaceae) in Amapá state, eastern Brazilian Amazonia

“…Over the past few years, new species and new occurrence records of Pouteria have been reported from the Brazilian Atlantic forest (Alves-Araújo and Alves 2011, 2012a, 2012bPopovkin et al 2016;Mônico et al 2017; Alves-Araújo 2018; Alves-Araújo and Mônico 2018). In the highly diverse Amazonia forest (ter Steege et al 2016), Pouteria is amongst the 10 top most species-rich tree genera (ter Steege et al 2016;Cardoso et al 2017), but still remains poorly studied in this biome.…”

Synopsis of Orchidaceae from Serra do Urubu: an area of montane forest, Pernambuco State, Brazil

“…The Atlantic Forest north of Rio São Francisco [also known as Pernambuco Endemism Center (Prance 1982)] has been far less studied than the southern portion. Furthermore, due to the several new taxa which have been recently described (Alves-Araújo & Alves 2011, 2012a, 2012b, Amorim & Alves 2012, Melo & Alves 2012, Araújo & Alves 2013, Amorin et al 2013, Costa-Lima & Alves 2013, Lourenço et al 2013, Terra et al 2013, Costa-Lima et al 2014, Pessoa & Alves 2014, Pessoa et al 2014a, 2014b, the Pernambuco Endemism Center is pontentially much more diverse than it is currently known.…”
