Sexual dimorphism in domesticated spinach, Spinacia oleracea, is thought to be determined by differential expression of floral organ identity genes. We examined the floral organ morphologies of seven species in the Chenopodiaceae, including two wild species of spinach, in order to gain insight into the evolution of floral reproductive strategy in this clade. The species within the Anserineae demonstrate extensive evolution in floral morphology and reproductive strategy, and Spinacia is unique for having been domesticated rather recently and for being dioecious. We found C. album to be hermaphroditic, C. foliosum and M. nuttalliana to be gynomonoecious, while C. bonus-henricus …
