The Immense Diversity of Floral Monosymmetry and Asymmetry Across Angiosperms [PDF]

open access: yes, 2018
Floral monosymmetry and asymmetry are traced through the angiosperm orders and families. Both are diverse and widespread in angiosperms. The systematic distribution of the different forms of monosymmetry and asymmetry indicates that both evolved numerous
