Flora do Espírito Santo: Mimoseae (Leguminosae): parte 1

Abstract

ResumoMimoseae, uma das tribos do clado Mimosoide -Leguminosae, possui 41 gêneros e cerca de 860 espécies. No Brasil, está representada por 16 gêneros e 614 espécies. Dada relevância do grupo para a flora brasileira e para a Mata Atlântica, este trabalho apresenta o estudo florístico dos gêneros Anadenanthera, Leucaena, Neptunia, Parapiptadenia, Parkia, Piptadenia, Plathymenia, Pseudopiptadenia AbstractTribe Mimoseae (Mimosoid clade -Leguminosae) has 41 genera and about 860 species, of which, 16 genera and 614 species are recorded in Brazil. As a very representative group from Brazilian flora and from Atlantic Rainforest, this paper aims to provide the floristic and taxonomic treatment for genera Anadenanthera, Leucaena, Neptunia, Parapiptadenia, Parkia, Piptadenia, Plathymenia, Pseudopiptadenia, and Stryphnodendron from Espírito Santo state (ES). Fieldwork was performed from April 2014 to July 2015 and vouchers housed at herbaria were examined. A total of 24 taxa (22 species and two varieties) were found in the state. Piptadenia (six spp.), Pseudopiptadenia (six spp.), Stryphnodendron (three spp.), and Anadenanthera (two spp.) are the richest genera amongst analyzed. Leucaena, Neptunia, Parapiptadenia, Parkia, and Plathymenia were represented by only one species each. Compared to the previously known for ES, results increased two genera and nine taxa (specific and infraspecific), as follow: Anadenanthera colubrina var. cebil, A. colubrina var. colubrina, A. peregrina var. peregrina, Neptunia plena, Piptadenia santosii, Pseudopiptadenia bahiana, P. psilostachya, Stryphnodendron polyphyllum, and S. pulcherrimum. Identification keys, descriptions, taxonomic comments, illustrations, and geographic distribution maps are provided.

Floristic survey of vascular plants of a poorly known area in the Brazilian Atlantic Forest (Flona do Rio Preto, Espírito Santo)

“…These efforts resulted in the publication of several taxonomic and floristic studies for selected plant families in subsequent years (e.g. Luber et al 2016 , Pena and Alves-Araújo 2017 , Silva et al 2017 , Chagas et al 2017 , Souza et al 2017 , Araújo et al 2018 , Torres-Leite et al 2018 , Moreira et al 2020a , Moreira et al 2020b ). Despite that, the State includes multiple knowledge gaps and botanical data remain scattered ( Garbin et al 2017 ).…”
