Which statement correctly describes genus in the binomial nomenclature?

• A. It is the second name in the binomial
• B. It is the first name, capitalized, identifying the plant
• C. It is the species epithet
• D. It is the cultivar name

Answer: (B)

Genus is the first part of the scientific name in binomial nomenclature, and it is capitalized. It identifies the broader group the plant belongs to. The second part is the species epithet, which designates the specific species within that genus and is not capitalized. Together, the two parts form the formal Latin name of the species (usually written in italics). A cultivar name, used for cultivated varieties, is not part of the binomial name and is shown separately, often in quotes or with cv. So the statement that the genus is the first name, capitalized, identifying the plant is the best description.
