Abstract
Betula papyrifera Marshall (Betulaceae) frequently is included in the indigenous Ohio flora. This status is based upon collections from a single tree in Lucas Co., Ohio, in 1934. Betula alleghaniensis Britton was collected from the same site at the same time. Neither of these species had been collected earlier in this section of Ohio, and neither has been observed since in the area. Both species are isolated from the main portions of their total range. The true status of Betula papyrifera in Ohio may never be known conclusively, but the native origin of the single Ohio tree is at best dubious.
