Abstract Although most North American violet species (Viola, Violaceae) produce both
showy chasmogamous (CH) flowers and inconspicuous cleistogamous (CL) flowers, some …

The production of open, chasmogamous (CH) flowers and closed, self-pollinated
cleistogamous (CL) flowers on an individual is an unusual mating system found in several …

Few studies of genetic variation have focused on species that reproduce through both
showy, chasmogamous (CH) flowers and self-pollinated, cleistogamous (CL) flowers. Using …

Inter–simple sequence repeat (ISSR) molecular markers were used to characterize inter-and
intrapopulation genetic diversity in populations of two contrasting species of Viola, Viola …

Abstract Viola reichenbachiana (2n= 4x= 20) and V. riviniana (2n= 8x= 40) are closely
related species widely distributed in Europe, often sharing the same habitat throughout their …

The genus Viola is a large and diverse group of flowering plants. The objectives of this study
were to develop and explore new morphological and molecular tools with horticultural and …

Viola flettii, Viola cuneata and Viola ocellata are sister species within the Viola canadensis
complex (Violaceae). All are endemics of western North America, growing in widely …

The reproductive biology of a plant species is important in the response of populations to
habitat fragmentation, especially if plant–pollinator interactions are disrupted. The genetic …

A mixed breeding system involving the production of chasmogamous and cleistogamous
flowers is common in most species of the genus Viola. This system can theoretically affect …

We performed demographic and molecular investigations on woodland populations of the
clonal herb Viola riviniana in central Germany. We investigated the pattern of seedling …
