Pollen morphology in relation to floral types and pollination syndromes in Pedicularis (Orobanchaceae)

Plant Systematics and Evolution, 2008
Floral diversification in the genus Pedicularis (Orobanchaceae) is remarkable among flowering plants. In this genus, floral morphology and pollinator behavior are closely co-adaptive. In the current paper, pollen grains of 23 representative species of Pedicularis mainly from North America, with two species from Japan and two species from China, whose ...

An exception to Darwin's syndrome: floral position, protogyny, and insect visitation in Besseya bullii (Scrophulariaceae)

Oecologia, 1995
Darwin pointed out that plants with vertical inflorescences are likely to be outcrossed if the inflorescence is acropetalous (flowers from the bottom up), the flowers are protandrous (pollen is dispersed before stigmas are receptive), and pollinators move upward on the inflorescence.

Floral Polymorphisms and Their Functional Significance in the Heterostylous Syndrome

1992
The emblem of the heterostylous syndrome is the positioning at equivalent levels of the stigmas of one floral morph and the anthers of one or two alternate morphs. Of less prominence in the syndrome are distinguishing characters of the pistils and stamens of the morphs, particularly of the stigmas and pollen grains.

A statistical Test for Floral Syndromes in Aquilegia (Ranunculacae)

Aquilegia flowers provide nectar to their pollinators via spurs that differ in length among species. In addition, flowers vary in colour, orientation, and to some extent also in shape. Traditionally, Aquilegia flowers have been classified into three floral syndromes associated to bee, hummingbird, or hawkmoth pollination.

Floral biology of Echinopsis chiloensis ssp. chiloensis (Cactaceae): Evidence for a mixed pollination syndrome

Flora - Morphology, Distribution, Functional Ecology of Plants, 2010
Abstract In this study the flower biology of Echinopsis chiloensis ssp. chiloensis, a columnar cactus occurring in Central Chile, is investigated, in particular its pollination syndrome, its visitors, their frequencies and behaviors and their pollination efficiencies. As statements on floral anthesis of this species are contradictory, this study also

Floral syndromes predict the most effective pollinators in five species of Salvia

American Journal of Botany
AbstractPremisePollination syndromes are suites of floral traits associated with the most effective functional group of pollinators. Particular floral traits may not necessarily preclude visitation by different visitor guilds that could also contribute to plant reproduction. The genus Salvia comprises ca.
