Abstract Detail
Systematics Pace, Matthew Charles [1]. What is the evolutionary significance of hybridization in North American Orchidaceae?: Evidence from Spiranthes and Platanthera. Spiranthes and Platanthera are the two largest orchid genera in North America, and hybridization is hypothesized to play a major role in the species-level evolution of both. However, molecular evidence to test this hypothesis has only begining to be explored. I will present new research into the Spiranthes cernua species complex and other groups which indicates hybridization has indeed ocurred, but not in the exact way as previously hypothesized. This research also indicates the species boundaries of some species are in need of realignment. Log in to add this item to your schedule
