Euphorbia antisyphilitica is a species of flowering plant in the spurge family Euphorbiaceae.  It is native to the Trans-Pecos of Texas and southern New Mexico in the United States as well as Chihuahua, Coahuila, Hidalgo, and Querétaro in Mexico.  Common names include candelilla and wax plant, but the latter is more often applied to members of the unrelated genus "Hoya".  It is shrubby and has densely clustered, erect, essentially leafless stems that are covered in wax to prevent transpiration. Croton nepetifolius (Croton nepetaefolius) is an aromatic species of flowering plant in the spurge family, Euphorbiaceae, that is native to northeastern Brazil.  It is commonly known as "marmeleiro vermelh" (red quince).  The plant has been used in folk medicine as a sedative, an orexigenic (appetite enhancer) and an antispasmodic (muscle contaction suppressor). Euphorbia pubentissima, known by the common names false flowering spurge and southeastern flowering spurge, is a species of plant in the spurge family.  It is native to the Southeastern United States where it is found in areas of sandy, open woodlands. Euphorbia griffithii, the Griffith's spurge, is a species of flowering plant in the spurge family Euphorbiaceae, native to Bhutan, Tibet and south west China.  It is a spreading, rhizomatous herbaceous perennial growing to 90 cm , with many erect reddish stems and narrow dark green leaves with red central veins, turning red and yellow in autumn.

It is the sole species in the monotypic genus, Ricinus, and subtribe, Ricininae.  The evolution of castor and its relation to other species are currently being studied using modern genetic tools.  It reproduces with a mixed pollination system which favors selfing by geitonogamy but at the same time can be an out-crosser by anemophily (wind pollination) or entomophily (insect pollination). Euphorbia bombensis, commonly called the Southern Seaside Spurge, is a species of flowering plant in the spurge family.
