Pouteria synsepala (Sapotaceae: Chrysophylloideae): a new species from the northern littoral of Bahia, Brazil

Abstract

A new species of Pouteria from the Atlantic Forest area of the northern littoral of Bahia State, Brazil, is described and illustrated. Pouteria synsepala, whose epithet refers to the basally united sepals, a feature rare in the genus, resembles P. salicifolia in its narrowly elliptic leaves, but differs by the angle of secondary veins in relation to the midrib, pentamerous flowers, and stamens adnate to the corolla tube from the base to the tube orifice. Micromorphological studies revealed different patterns of stomate and wax morphology in the two species, providing further justification for the recognition of P. synsepala.

Endemic angiosperms in Bahia Coastal Forests, Brazil: an update using a newly delimited area

“…For instance, about 41.5% of all new angiosperms in the Brazilian flora described between 1990 and 2006 are endemic to the Atlantic Forest (Sobral & Stehmann 2009). Moreover, 23 species of angiosperms endemic to BCF were described between 2015 and 2017 (e.g., Araújo et al 2015, Santos et al 2015, Abreu & Giulietti 2016, Côrtes et al 2016, Ferreira et al 2016, Marinho & Lucas 2016, Popovkin et al 2016, Ribeiro et al 2016, Terra-Araujo et al 2016, Daly & Melo 2017, Gonçalez et al 2017.…”

Typifications in neotropical Sapotaceae

“…Sapotaceae has 65-70 genera with around 1,250 species and is an important plant component from tropical regions in the world (Swenson et al 2020). It is an economically interesting family by providing latex-derived products such as gutta-percha and chewing gum, valuable and durable timber and edible fruits (Pennington 1990(Pennington , 1991.…”

“…In Linnaeus' first edition of Species Plantarum (Linnaeus 1753), the author began the taxonomic history of Sapotaceae by describing six species: Achras zapota L. (= Manilkara zapota (L.) P. Royen), Chrysophyllum cainito L., Mimusops elengi L., Mimusops kauki L. (= Manilkara kauki (L.) Dubard), Sideroxylon inerme L. and Sideroxylon spinosum L. However, Jussieu's Genera Plantarum (Jussieu 1789) was the first work that recognised it as a homogenous group, then called "Sapotae". Since then, many morphological classification proposals have been reported, such as Baehni (1938Baehni ( , 1965, Lam (1939), Aubréville (1964) and Pennington (1990Pennington ( , 1991. Currently, based on phylogenetic and morphological analysis, Sapotaceae is divided into three monophyletic subfamilies: Sarcospermatoideae, Sapotoideae and Chrysophylloideae (Swenson and Anderberg 2005).…”

“…Pouteria and Chrysophyllum are the largest genera in Sapotaceae with around 270 and 100 accepted names, respectively (The Plant List 2013). Furthermore, for tropical Americas, they have together more than 60 synonyms, most of them applied to Pouteria (around 45) (Pennington 1990(Pennington , 1991.…”

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.…”
