Flowering as a Reproductive Strategy of the Sexes of the Gynodioecious Silene acaulis
Populations of the alpine cushion plant Silene acaulis in Colorado have female and hermaphrodite plants, each with respective flowering and fruiting throughout their growing season. In order to understand the differences between the two sexes, I collected flowering data throughout the season as well...
