Stigma-height dimorphism is a sexual polymorphism in which plant populations are composed of two floral morphs that differ significantly in style length but not anther position. The morphs exhibit approach and reverse herkogamy, floral designs that in most species typically occur as monomorphic conditions. We investigated the floral biology of stigma-height dimorphism in the Mediterranean geoph...

BACKGROUND AND AIMS Floral design in self-compatible plants can influence mating patterns. This study investigated Narcissus longispathus, a self-compatible bee-pollinated species with wide variation in anther-stigma separation (herkogamy), to determine the relationship between variation in this floral trait and the relative amounts of cross- and self-fertilization. METHODS Anther-stigma sepa...

This article explores the correspondences and differences in terms of color design between two screen versions Black Narcissus, a popular novel by Rumer Godden published 1939. Conceptual approaches drawn upon include ideas “the figural,” intertextuality hybridity as central to understanding how Narcissus operates on many complex levels, arguing that is key expressive mode their articulation. Po...

Darwin's early work on heterostyly and related style polymorphisms (the presence of two or three style morphs within a population) generated much interest to understand how precise interactions between ecological and genetic mechanisms influence the evolution of floral diversity. Here we tested three key hypotheses proposed to explain the evolution of heterostyly: (i) the presence of self-incom...
