Two new species of <I>Leandra</I> s. str. (<I>Melastomataceae</I>) from the Atlantic Forest in Espírito Santo, Brazil

Abstract

Two species of Leandra that occur in the Atlantic Forest, in the state of Espírito Santo, eastern Brazil, are described and illustrated here. Leandra cristata has been found in the understory of montane rain forest, and can be recognized by the distinct nodal ridges on the young branches, by the leaves with decurrent bases and transversal nerves consistently perpendicular to the main nerve, by the triangular external teeth, and by the dorsal bump on the stamen connective. Leandra fontanae has been found in shrubby vegetation on inselbergs, and can be recognized by the small and cordate leaves with five main nerves plus a faint submarginal pair, by the apical and lateral inflorescences made up by single dichasia or a triad, by the flowers mostly 4-merous and by the 2-celled ovary.

Two new species of Miconia s.lat. (Melastomataceae) from Espírito Santo, Brazil

“…Among the species in the Leandra s.str. clade it is morphologically similar to Miconia fontanae (former Leandra fontanae ; Reginato and Goldenberg 2013). The latter belongs in a small subclade mainly composed by species endemic to the Espírito Santo state (Capixabae clade, following Reginato and Michelangeli 2016).…”

Melastomataceae Juss. do Complexo de Serras da Bocaina e de Carrancas, Estado de Minas Gerais, Brasil: inventário e comparação florística

“…A partir dessas listagens foi feita uma matriz de ausência/ presença das espécies de Melastomataceae nas áreas. Inicialmente, as listagens foram atualizadas para incluir as espécies novas descritas nos últimos anos (Goldenberg 1999, , Freitas et al 2013, Pataro et al 2013, Reginato & Goldenberg 2013, Romero 2013a, Romero & Castro 2014, Romero & Versiane 2014, Guimarães & Freitas 2015, Bacci et al 2016, Meyer et al 2016, Pataro et al 2017, Romero & Woodgyer 2018) e a nomenclatura revisada com base nos estudos taxonômicos e filogenéticos (Martins 1989, Renner 1990, Renner 1994, Koschnitzke 1997, Rodrigues 2009, Martins & Almeida 2017, Guimarães et al 2019. Os nomes das espécies foram atualizados e todas as sinonímias eliminadas com base na Lista do Brasil (Goldenberg et al 2020).…”
