New records of Euphorbia dioeca Kunth (Euphorbiaceae) for the States of Minas Gerais, Pernambuco, and Sergipe, Brazil: expanding knowledge of urban ruderal flora

Abstract

Euphorbia dioeca Kunth is a ruderal herb native to Brazil,widely adapted to anthropized environments. This study presents the first records of the species for the states of Minas Gerais, Pernambuco, and Sergipe, expanding its distribution and reinforcing its presence in stressful urban environments. These new data highlight the importance of floristic studies specific to ruderal flora, particularly in urban areas, where species such as E. dioeca may be underrepresented due to a lack of targeted collections and taxonomic biases.
