Nothospecies

The fourth species, the nothospecies Fragaria × ananassa, was originally established for the hybrids F. chiloensis × F. virginiana, which had originated under cultivation and are known as the large-fruited garden strawberries. When the hybrid populations in the coastal regions of northwestern North America were identified as introgressants of the same two octoploid species, they were combined with the cultivated garden strawberries into the nothospecies F. ×ananassa.

For our treatment we designate hybrid species (nothospecies) by prefix with a multiplication sign placed flush with the species epithet (×; Art H.1.1; H.3A.1 of the International Code of Botanical Nomenclature, Greuter et al. 2000) only if they are of restricted distribution and are sympatric with their putative parents.

The number that precedes each species is presented to help determine parentage of nothospecies (i.e., hybrids). Therefore, all nothospecies included in the manual are provided with a numeric formula (e.g., 1 × 3) in addition to the scientific name (when present).
