Evolution of floral zygomorphy in androecium and corolla in Solanaceae [PDF]
Journal of Systematics and Evolution, 2017 AbstractIn Solanaceae, a group dominated by actinomorphic‐flowered species, floral zygomorphy is frequently observed among the early‐branching clades. Morphological studies indicated that a zygomorphic androecium is much more common than a zygomorphic corolla in the family.

Types of Androecium in the Fabaceae of SW Europe [PDF]
Annals of Botany, 1999 Abstract We studied the morphology of the androecium in 168 species and subspecies of Fabaceae from SW Europe and its relationship with nectar production. Six androecium types were recognized: monadelphous; pseudomonadelphous without basal fenestration; pseudomonadelphous with basal fenestration; diadelphous; reduced diadelphous; and androecium with ...

The Discovery of Polyandry in Curculigo (Hypoxidaceae): Implications for Androecium Evolution of Asparagoid Monocotyledons [PDF]
Annals of Botany, 2007 Individual flowers of the monocot Curculigo racemosa (Hypoxidaceae, Asparagales) are regularly polyandrous. To evaluate the significance of this almost unique character among Asparagales for flower evolution of asparagoid monocots, flowers of C. racemosa were studied comparatively.Anthetic flowers as well as early floral developmental stages were ...
