Notice that the genus name is always capitalized; the species name is not capitalized. The scientific name is also written in italics; if italics are not available, the genus name and specific epithet are underlined. (Newspapers usually break these rules.) If a species is written more than once, it is accepted convention to write out the full genus and species name the first time and to abbreviate the genus name every time thereafter. For example, if white oak is being described, the first use would be written as Quercus alba, and each subsequent naming would appear as Q. alba.
