betweenflower

Betweenflower is a term used in botany and horticulture to describe a flower whose traits lie between two varieties or species. The concept encompasses phenotypic mosaics, color gradations, and partial genetic composition that create intermediate features in a single bloom.

Etymology: The word is a portmanteau of between and flower, reflecting its focus on intermediacy within floral structures. It is applied to both natural occurrences and cultivated varieties where traits do not fit neatly into a single category.

Forms and causes: Betweenflowers can arise through somatic mutation, genetic chimerism, polyploidy, or deliberate breeding. Color patterns may show gradient or marbling, while morphological traits such as petal shape or venation may appear intermediate. Scientific analyses may involve genetic testing or microscopic examination to determine mosaicism.

In horticulture and plant taxonomy, the term helps describe unusual phenotypes that challenge rigid variety boundaries. Breeders may use it as a descriptive label for promising lines and for marketing; scholars may discuss it in the context of phenotypic plasticity and speciation.
