Flora of Espírito Santo: tribe Microlicieae (Melastomataceae)

Abstract

Microlicieae is one of the most diverse tribes in Melastomataceae, comprising three genera: Microlicia (including the former Chaetostoma, Lavoisiera, Stenodon, and Trembleya), Poteranthera, and Rhynchanthera. It is characterized by anthers with a prolonged pedoconnective, capsular fruits, and reniform, oblong seeds with a foveolate testa. This study presents a taxonomic treatment for the species of Microlicieae in the state of Espírito Santo. A total of ten species were registered in two genera, Microlicia (9 spp.) and Rhynchanthera (1 sp.). Of these, three are new species of Microlicia: M. caparaoensis is endemic to the Caparaó National Park; M. capixaba and M. misteriosa are endemic to a single inselberg, the “Alto Misterioso”, in São Roque do Canaã. A fourth species was kept as Microlicia sp., since further studies will be necessary to confirm its identity. We also provide an identification key, morphological descriptions, distribution data, and comments for all species.

“…For the state, besides the floras for the genera Miconia Ruiz & Pav. (Bacci et al 2016a) and Bertolonia Raddi (Bacci et al 2017), and the tribes Cambessedesieae (Bochorny & Goldenberg 2017) and Microlicieae (Versiane et al 2022), floristic studies were carried out in the "Área de Proteção Ambiental de Mestre Álvaro" (APAMA) (Iglesias & Dutra 2017), in the "Parque Estadual do Forno Grande" (PEFG) (Meirelles & Goldenberg 2012) and in the "Estação Biológica de Santa Lúcia" (EBSL) (Goldenberg & Reginato 2006), respectively with 26, 39 and 57 species. The study area of this work is located in the same municipality of EBSL, Santa Teresa, and is called "Parque Natural Municipal de São Lourenço" (PNMSL).…”
