A category
of classification ranking between the family and
the species.
For example, the several species of oak collectively
form the genus Quercus; of daylilies, the several
species plus the many cultivars form
the genus Hemerocallis; of horses, asses (note
the comma between the two preceding words) and zebras,
the genus Equus. (But see Hemerocallis)
Plural, genera. |
