610204-05 The Betula papyrifera aggregate B. kenaica, B. papyrifera
Geography: North American.
Notes: Furlow (1997) considered Betula papyrifera, B. kenaica, and the non-arctic B. occidentalis (sensu Hooker) to be closely related and the two latter as likely to have been derived from B. papyrifera. As such, they could be considered an aggregate.
