Associations between sex-organ deployment and morph bias in related heterostylous taxa with different stylar polymorphisms
(Wiley-Blackwell, 2017)
PREMISE OF THE STUDY: Populations of heterostylous species are characterized by two or three floral morphs with reciprocal positioning of stigmas and anthers. Theoretical models predict equal morph frequencies (isoplethy) ...

Strong Conservatism of Floral Morphology During the Rapid Diversification of the Genus Helianthemum
(Wiley-Blackwell, 2023)
Premise: Divergence of floral morphology and breeding systems are often expected to be linked to angiosperm diversification and environmental niche divergence. However, available evidence for such relationships is not ...
