Total Pollen

Stigmatic pollen loads were analyzed from naturally pollinated pin and thrum form flowers of Amsinckia douglasiana and A. vernicosa var. furcata. Pin stigmas captured more total pollen than thrum stigmas. Pins experienced either net self-pollination or random pollination. Thrum stigmas experienced significant disassortative pollination. Comparing pollen loads from intact and emasculated thrum flowers of A. douglasiana indicated that self-pollination and geitonogamy were relatively unimportant in the pollination of the thrum form. The level of disassortative pollination of A. vernicosa var. furcata does not appear to be high enough to account for the level of disassortative mating observed by progeny testing, suggesting that this species may possess an incomplete stylar self-incompatibility system such as has been reported in A. grandiflora.

Corolla Length

Distyly is a floral polymorphism in which about half of the plants in a population have long styles and short stamens (Pin), whereas the remainder possess short styles and long stamens (Thrum). It has been suggested that the relative position of anthers and stigmas in distylous flowers enhances pollen flow between flowers of opposite morphs (legitimate pollination), in comparison to pollen flow between flowers of the same morph (illegitimate pollination). We studied the floral morphology of both floral morphs (six variables) in Palicourea padifolia (Rubiaceae) and found significant differences between floral morphs in floral traits that define the floral polymorphism. However, the correlations between morphological traits that define the floral morphs (morph-specific), and the significant correlations were stronger in the short styled morph. The morph-specific correlation patterns among some of the floral traits suggest differential selective pressures between floral morphs, regardless of corolla length.
