Croton

Ny Croton dia vondron-karazana zavamaniry mamony ao amin' ny fianakaviana Euphorbiaceae, ao amin' ny filaharana a Malpighiales. Miseho amin' ny endrika hazo sy hazobotry ary zavamaniry ahitra ny karazana ao amin' ny Croton. Iray amin' ny vondron-karazana lehibe indrindra amin' ny angiôsperma izy io, misy karazany 2 216, izany hoe eo amin' ny 0,5 % amin' ny karazana zavamaniry mamony rehetra.

Ity vondron-karazana ity dia miavaka noho ny fahasamihafan' ny endrika misy ao aminy, manomboka amin' ny zavamaniry ahitra ka hatramin' ny hazobotry sy ny hazo. Hita manerana ny faritra trôpikaly sy sobtrôpikaly manerana izao tontolo izao ny karazana misy ao aminy. Ny Croton tiglium, izay teratany any Azia Atsimo-Atsinanana, no karazana fantatra indrindra amin' ity vondron-karazana ity.

Ny zavamaniry ao amin' ny vondron-karazana Croton dia tsy tokony afangaro amin' ny "croton" amin' ny fitenin' ny mpamboly voninkazo, izay tsy inona fa ny Codiaeum variegatum. Nofaritan' ilay mpahay zavaboary soedoà Carl von Linné (1707-1778) tamin' ny taona 1753 ity vondron-karazana ity. Avy amin' ny teny grika hoe "Kroton" (κρότος / krótos), izay midika hoe "kongona", ny anaran' ilay vondrona, noho ny fitovian' ny voany amin' ny kongona. Ao amin' ny fanasokajiana filôjenetika APG III (2009) sy amin' ny fanasokajiana klasika nataon' i Cronquist (1981), dia voatendry ho ao amin' ny fianakaviana Euphorbiaceae izy io.
