In biology, each species is generally identified by two terms: the first is the genus to which it belongs, and the second is the specific epithet that distinguishes it from others in that genus (e.g., Quercus suber, cork oak). The genus name always has an initial capital; the specific epithet is never capitalized, even though it may be derived from a proper name (e.g., keranda nut, Elaeocarpus bancroftii). Both terms in the binomial are italicized. Based on the system of classification developed by Carolus Linnaeus.
