Division

Entire
Taxonomic group under the order level and above the genus level
Family

Foliage
Group of plants within a species having distinct variations that occur sporadically and naturally
Forma

Identification key
Primary taxonomic group, separating plants from animals

Species
Classification name that follows the genus name in scientific nomenclature
Specific epithet
Group of plants within a species having distinct differences that occur naturally and usually within a specific geographic region
Subspecies
Science that studies the description, denomination, and classification of living organisms based on their similarities and differences
Taxonomy
Naturally occurring subdivision of a species having a distinct difference and breeding true to that difference
Variety
