Amelanchier (Shadbush) of the Potomac Gorge: Taxonomic and Evolutionary Complexity
Speaker: Christopher Frye, Maryland State Botanist, DNR Wildlife and Heritage Service
Description: Fernald remarked that "no genus in North America, except of course Rubus and Crataegus, has offered so much perplexity ... as Amelanchier." The Potomac Gorge is home to several Amelanchiers that illustrate the complex evolutionary relationships within the genus. Chris will explain how recent evidence provides insights into the diversity of Amelanchier at this site.
Chris Frye has been studying this fascinating genus of the Rose Family for 10 years. He is a member of the Amelanchier systematics group that published the treatment of the genus for the Flora of North America.
