Abstract
Abstract Euphorbiaceae is one of the largest and more complex families of angiosperms with 6,745 species and 218 genera. Dalechampia comprises approximately 130 species, with pantropical distribution, the genus presents pseudantial inflorescence with bilateral symmetry, and this characteristic differs from the others taxons in the family. Were registered 15 Dalechampia species for Espiríto Santo, of which D. margarethiae until then, it was endemic of state recording here a new occurrence for the state of Minas Gerais. Dalechampia leandrii, D. micromeria, and D. stipulacea constitute new records for the state. After expeditions in the field to observe and collect samples, bibliographic revision, and examination of herbarium specimens, we present a synopsis of Dalechampia from Espirito Santo state, in which we provide morphological illustration, an identification key, distribution maps, and comments about each taxon.
Highlights
Euphorbiaceae Juss. is one of the largest and most complex families of Angiosperms (Webster 1994; Wurdack et al 2005) with about 6,745 species and 218 genera (APG IV 2016)
As part of the studies in Neotropical Dalechampia (Pereira-Silva et al in prep.), here we present a synopsis of the species occurring in the Espírito Santo state, as well as an identification key, character illustration, distribution maps, and comments about each taxon
Study area The Espírito Santo state is located in the southeastern region of Brazil and comprises an area of 97,123 km2 (IBGE 2018)
Summary
Euphorbiaceae Juss. is one of the largest and most complex families of Angiosperms (Webster 1994; Wurdack et al 2005) with about 6,745 species and 218 genera (APG IV 2016). Is one of the largest and most complex families of Angiosperms (Webster 1994; Wurdack et al 2005) with about 6,745 species and 218 genera (APG IV 2016) It presents greater diversity in tropical and subtropical regions, especially in the American and African continents (Lucena et al 2009). Among the tribes of Acalyphoideae, Plukenetieae deserves to be highlighted because it comprises 17 genera and more than 350 species widely distributed in tropical regions (Gillespie 1994; Webster 1994; Govaerts et al 2000; Radcliffe-Smith 2001). Dalechampiinae contains only Dalechampia, classified into six sections and approximately 130 species with Pantropical distribution (Webster 1994; Pereira-Silva et al in prep.). As part of the studies in Neotropical Dalechampia (Pereira-Silva et al in prep.), here we present a synopsis of the species occurring in the Espírito Santo state, as well as an identification key, character illustration, distribution maps, and comments about each taxon
