Etymology: "Ricinuses" is simply the plural of "ricinus", the Latin name for the castor-oil plant, so the word's story is the story of that plant. "Ricinus" is a Latin term applied to the castor-oil plant (Ricinus communis) and its genus, and it was taken into English as a botanical name. Its plural follows the regular English pattern of adding "-es" to a noun ending in "-us", with the classical Latin plural "ricini" used less often.
