Abstract

Abstract Belonging to Malpighiales, Humiriaceae has about 65 species in eight genera, distributed almost exclusively in the Neotropics, occurring from southern Brazil to Central America. In Brazil, 35 species have been recorded (ca. 54% of the family’s diversity), wherein the greatest diversity is found in the Amazon (27 spp.), Atlantic Forest (9 spp.) and Cerrado (6 spp.) domains. This work is part of the “Flora do Espírito Santo” project, which aims to contribute to the knowledge of the state’s floristic diversity. Field expeditions were carried out from January/2019 to March/2020. Humiriaceae, in the state of Espírito Santo, is represented by six species distributed in four genera: Humiria, Humiriastrum, Sacoglottis and Vantanea. Among the registered genera, Vantanea is the most diversified, with three species. In the dense rain forest, all Humiriaceae species recorded here were found, followed by pioneer formations of restingas, with four species and seasonal semideciduous forest, with one species. The main morphological characters that assist in the delimitation of Humiriaceae species in Espírito Santo, are androecium characteristics, such as length (homodynamous or heterodynamous), number of stamens and the number of their series, as well as anther morphology.

Highlights

Humiriaceae belongs to Malpighiales (APG IV 2016) and has 65 species in eight genera, of which Endopleura and Hylocarpa are represented by only one species (Wurdack & Zartman 2019)
Available taxonomic information about Humiriaceae in southeastern Brazil can be found in Pereira (1966), with three genera and three species for the state of Guanabara (Rio de Janeiro); Giordano (1996), with four genera and nine species for the state of Rio de Janeiro; Silvestre (1981) for the Fontes do Ipiranga State Park, São Paulo; Mendonça (2004), with three genera and four species for the Flora de GrãoMogol - Minas Gerais; and Fantinati et al (2004), with three genera and three species for Flora da Serra do Cipó - Minas Gerais

Summary

Introduction

Humiriaceae belongs to Malpighiales (APG IV 2016) and has 65 species in eight genera, of which Endopleura and Hylocarpa are represented by only one species (Wurdack & Zartman 2019). The family is almost exclusively Neotropical, occurring mainly in the tropical forests from southern Brazil to Central America (Cuatrecasas 1961), except for Sacoglottis gabonenses (Baill.) Urban (449: 1877) which occurs along the African west coast (Cuatrecasas 1961). Humiriaceae is composed mostly of shrubs or treelets, with alternate leaves having serrate (e.g., Humiriastrum and Sacoglottis) or entire (e.g., Humiria and Vantanea) leaf margins. The most important reproductive structure for genera and/or species delimitation is the morphological variation of the androecium (Wurdack & Zartman 2019). Available taxonomic information about Humiriaceae in southeastern Brazil can be found in Pereira (1966), with three genera and three species for the state of Guanabara (Rio de Janeiro); Giordano (1996), with four genera and nine species for the state of Rio de Janeiro; Silvestre (1981) for the Fontes do Ipiranga State Park, São Paulo; Mendonça (2004), with three genera and four species for the Flora de GrãoMogol - Minas Gerais; and Fantinati et al (2004), with three genera and three species for Flora da Serra do Cipó - Minas Gerais
