Staminate flowers of andromonoecious species are thought to be produced to increase
reproductive success through enhancing male function or diverting resources from …

Sex expression in Sagittaria guyanensis HBK subsp. lappula (D. Don) Bojin is typically
andromonoecious while the other species in the same genus are basically monoecious. The …

The diversity of plant breeding systems provides the opportunity to study a range of potential
reproductive adaptations. Many mechanisms remain poorly understood, among them the …

Gender in flowering plants is governed by a complex interplay of genetic and environmental
factors. The perennial aquatic herb Sagittaria latifolia displays remarkable variation within …

Gynomonoecy, a sexual system in which plants have both pistillate (female) flowers and
perfect (hermaphroditic) flowers, occurs in at least 15 families, but the differential …

In protogynous plants, female flowers of early blooming plants are at a reproductive
disadvantage because they cannot set fruit due to the lack of available pollen. To study this …

Sagittaria lancifolia subsp. lancifolia is described as cosexual (monoecious), but the study
population consisted of 84% cosexuals that typically had 35% pistillate buds and 16 …

Gynomonoecy is the sexual system in which individual plants bear both female and bisexual
flowers. Little attention has been paid to the adaptive significance of this sexual system …

• Premise of the study: Knowledge of the functional sex expression of flowers is critical to
identify the breeding system and potential for outcrossing in individuals but difficult to …

Many species of angiosperms have mixed mating systems in which a portion of progeny
result from self-fertilization and some from outcrossing. We show that Agalinis neoscotica …
