members of a species uniquely adapted to an ecologically distinct landscape (e.g. Quercus garryana breweri and Quercus garryana semota, white oaks growing in the Siskiyou Mountains or the Sierra Nevada, respectively). In contrast, cultivars are members of a species that have been deliberately selected for according to human need (e.g. Oryza sativa indica and Oryza sativa japonica are Asian rices bred to be long or short grained, respectively). See scientific name, variety.
