Abstract

Platanthera aquilonus is largely autogamous but not agamospermous. Autogamy is facultative, and mosquitoes sometimes act as vectors, the pollinaria attaching to their eyes. Platanthera dilatata and P. huronensis are outcrossing or geitonogamous with pollinaria positioned to attach to the pollinator’s proboscis. Platanthera huronensis is pollinated by a variety of insects. Platanthera stricta is self-compatible, but outcrossing produces seeds with a higher percentage of normally developed embryos. Autogamy and agamospermy are absent. Platanthera sparsiflora is pollinated by small moths. A medial labellar ridge forces lateral entrance to the nectar spur, resulting in pollinaria attachment to the proboscis.
