race

noun

A group or assemblage of organisms that exhibits general similarities but is not sufficiently distinct from other forms to constitute a species (e.g. the three races of avocado (Persea Americana), Mexican, Guatemalan, and West Indian, of which the first is sometimes designated as a separate species, although it hybridizes freely with the other two); sometimes used for individuals of a particular geographical area, in this sense then equivalent to an ecotype (which is not a botanical term).
