The pollination biology and flower visitors of Lobelia spicata, an herbaceous prairie
perennial, were examined, and this species was found to be xenogamous, self-compatible …

Female flowers of gynodioecious species (plants with either female or hermaphroditic
flowers) are typically smaller with no reward for pollinators. We proposed and tested that …

Premise of research. In gynodioecious species, female plants are often at a disadvantage
due to their reliance on hermaphroditic pollen donation and lower attractiveness to …

In many gynodioecious species, gender differences have been documented. Previous
studies on populations of Lobelia spicata consistently documented hermaphrodites having …

The breeding system, flowering display, and fruiting pattern of Calochortus leichtlinii
Hook.(Liliaceae) was studied in the eastern Sierra Nevada. This species is capable of both …

Gynodioecy is a dimorphic breeding system in which male-sterile individuals (ie, females)
coexist with hermaphroditic individuals in populations. Previous studies of two species of …

Lactoris fernandeziana, monotypic in its family, is endemic to the cloud forests of Robinson
Crusoe Island. Although there has been considerable study of the relationships of Lactoris …

Field studies were carried out on the pollination of Sarracenia flava L. during three flowering
seasons in relict bogs of the piedmont region of North Carolina. Flowering occurs in latter …

Methods Throughout each population's flowering period in 1988 I matched pairs of
individual plants for flower number, date of first flower, and density of surrounding flowers …

The hypothesis of this study was that in the Galápagos Islands, fruit and seed set via
nocturnal pollination would exceed that of diurnal pollination due to greater insect activity at …
