Chupire

Chupire (Euphorbia calyculata) is a succulent or semi-succulent plant in the large family Euphorbiaceae, found in tropical and subtropical dry habitats of Mesoamerica and northern South America including Venezuela. The genus Euphorbia is one of the most species-rich genera of flowering plants, encompassing an enormous range of growth forms from tiny annual herbs to massive succulent trees, united by the presence of a milky, toxic latex and a specialized inflorescence called the cyathium. E. calyculata grows as a shrub or small tree in dry to seasonally dry tropical environments, contributing to the structure of thornscrub, dry forest edges, and rocky hillside vegetation. The Chupire is assessed as Least Concern by the IUCN, indicating stable populations within its native range. Its latex, like that of many Euphorbias, contains diterpene esters and other irritant compounds that deter herbivory. In some regions, the plant has traditional uses in folk medicine and as living fences or hedgerows, exploiting its branching structure and drought tolerance. The species contributes to the floristic diversity of Neotropical dry vegetation, a biome under increasing pressure from agricultural expansion and climate-driven aridity.
