A pine cultivar created named to Evans; what is the correct scientific name format?

• A. Pinus strobus 'Evans'
• B. Pinus strobus 'Evansy'
• C. Pinus strobus var. Evans
• D. Pinus nigra 'Evans'

Answer: (A)

Cultivar names are written as the genus and species in italics, followed by the cultivar epithet in single quotes. The cultivar epithet is capitalized and not italicized. For a pine cultivar named after Evans in the species Pinus strobus, the correct format is Pinus strobus 'Evans'. This shows it’s a cultivated variety of the Eastern white pine, distinguished by the quotation marks around the name. The other options don’t fit: using Evansy isn’t a standard cultivar epithet and lacks the proper quotation format; using var. would denote a natural variety rather than a cultivated cultivar; and Pinus nigra would imply a different species altogether.
