Euphorbia tithymaloides is a perennial succulent spurge. Euphorbia obesa is a subtropical succulent species in the genus "Euphorbia". Some, such as "Euphorbia canariensis", are succulent and resemble cacti because of convergent evolution. Many are grown as ornamental plants, such as poinsettia ("Euphorbia pulcherrima"). The characteristic plants are the endemic subfamily Didiereoideae, baobabs, and "Euphorbia" species. The frequently showy pair of bracts of "Euphorbia" species in subgenus "Lacanthis" are the cyathophylls. The entire subtribe Euphorbiinae now consists solely of the genus "Euphorbia". "Euphorbia milii" can be propagated from cuttings. This species is the type species of the genus "Euphorbia". Toxicity is documented in most members of the genus Euphorbia. The present taxon ""Euphorbia"" corresponds to its own former subtribe, the Euphorbiinae. Euphorbia ingens is a species of plant in the genus "Euphorbia" and the family Euphorbiaceae. The latex of "Euphorbia resinifera" contains Resiniferatoxin, an ultra potent capsaicin analog. Warming's doctoral thesis (in Danish) dealt with ontogeny of the cyathia of Euphorbia (Euphorbiaceae). See List of "Euphorbia" species for complete list.
