ABSTRACT

Dalechampia burchellii (Euphorbiaceae): rediscovery, new synonyms, and update of its geographic distribution area). Dalechampia comprises around 72 species, among them, 48 are endemic to Brazil, occurring in all regions and phytogeographic domains. After extensive analysis of herborized material and in situ collection, we discovered the identity of D. burchellii and updated the morphological description and geographic distribution area of the species. We also present photographic records in the field, data on the habitat, phenology, and preliminary conservation status. Additionally, we present comments about the type of D. burchellii and included D. anomala and D. bangii as new synonyms.
