Abstract Detail
Systematics Pace, Matthew Charles [1]. Updating the Orchid Flora of Eastern North America: Revising Gleason & Cronquist. The classic florisitc work of Eastern North America -Gleason & Cronquist's Manual of Vascular Plants- is currently under revision. Incorperating new molecular evidence and expanded morphometric analyses, an overview of the treatment for Orchidaceae is presented, with particular focus on the two most sopecies-rich genera: Platanthera and Spiranthes. This research shows 1) Eastern North America is the second most species rich region of North America, 2) Cryptic diversity remains in some groups, whereas others have suffered from over-splitting, and 3) many species are declining across the region.
