Reports of Paeonia brownii from Canada evidently stem from early confusion between Vancouver, British Columbia, and Vancouver, Washington (H. J. Scoggan 1978-1979, vol. 3). The type of P. brownii was collected on Mount Hood in Oregon, about 75 kilometers from Fort Vancouver (now Vancouver), Washington, which was a base for the collector, David Douglas.
