Sexual expression has been used as a distinctive character among the clades of the genus Piper. Unisexual flowers are described for Paleotropical species, which are usually dioecious, whereas bisexual flowers are associated ...

The endemic and rare Solanum vespertilio and S. lidii from the Canary Islands are notable in being andromonoecious, self compatible, highly heterandrous (with short reward= anthers and one very long pollination= anther), ...

In environments with high fire frequency the impoverishment of abiotic resources may favor male sexual expression in plants as it is less costly than female expression. Also, fire can modify pollinator communities and thus ...

Based on the hypothesis that both plant size and local conspecific density influence allocation to female/male functions, we explored the relationship between plant height, local conspecific density, sexual expression, and ...

The degree of sexual dimorphism in flowers and inflorescences can be evaluated early in flower development through the study of floral organ size co-variation. In the present work, the gynoecium-androecium size relationship ...

Ovule abortion may lead to the partial or complete reduction of the number of functional ovules in the ovary and then is the primary factor that determines the sexual expression of the plant. In different species, ovule ...

We review the hypothesized origin and the methods of arrival of the angiosperm colonists to the Juan Fernandez Islands. We also summarize the dispersal capabilities of the current flora, including data on fruit type, fruit ...
