The evolution of polymorphic sexual systems in daffodils (Narcissus).

The New phytologist - 1 Jan 2005

Barrett Spencer C H, Harder Lawrence D

Abstract excerpt

Narcissus, the daffodil genus, exhibits an unusual diversity of sexual systems, with populations that are monomorphic, dimorphic or trimorphic for style length. Associated with this variation are striking differences among species in floral morphology and pollination biology. This diversity provides an opportunity to investigate the evolution of mating polymorphisms, and to determine how floral morphology...
