The S Iberian Peninsula and NW Africa constitute one of the main hotspots for plant
biodiversity within the Mediterranean Basin. At the core of this hotspot, across the Strait of …

The effects of the present biodiversity crisis have been largely focused on the loss of
species. However, a missed component of biodiversity loss that often accompanies or even …

Floral polymorphisms provide suitable model systems to test hypotheses concerning the
evolution of outbreeding in plants. Although heterostyly has evolved in more than 28 …

The evolution of self-incompatibility (SI) has been debated since its genetic bases were first
fully described over half a century ago. The diversity of SI systems and their scattered …

Pollinators may generate selective pressures that affect covariation patterns of multiple traits
as well as the mean values of single floral morphological traits. Berg predicted that flowers …

Besides being one of the most popular ornamental bulbs in western horticulture, the
Mediterranean genus Narcissus has been the subject of numerous studies focusing on a …

Abstract Aim Our aims were:(1) to reconstruct the phylogenetic relationships of daffodils
(Narcissus), focusing on the lowland subgenus Hermione and the mountain section …

The taxonomy of all species of Narcissus (Amaryllidaceae), an important horticultural crop,
has not been investigated recently. As a new approach, genome size was determined by …

Heterostyly is a sex polymorphism that has challenged evolutionary biologists ever since
Darwin. One of the lineages where heterostyly and related stylar conditions appear more …

Darwin proposed that the driving force for the evolution of style polymorphisms is the
promotion of cross‐pollination between style morphs, through accurate placement of pollen …
