Oak-Leaved Thorn-Apple (Datura quercifolia Kunth)
Also known as Chinese thorn-apple.
Calflora considers Datura ferox L. to be a synonym of this species. However, POWO lists this name as a separate species. We have not yet examined or resolved this inconsistency. For now we use a scheme that seems consistent with BONAP's and Calflora's treatments.

This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.
Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.
As with many of the Datura species, the exact native range of this is unknown and sometimes disputed. Assessing the distribution of this species is also complicated by disagreements about its taxonomy. For now our map is based loosely on BONAP's. We chose to mark eastern and western populations as introduced because they are separated from the native population by signficant geographic divides in which the plant does not occur; we may update this if we find new information suggesting it would be better to mark some of this range as Expanded.
↑Notes
The common name "Chinese thorn-apple" is misleading as this species is neither native to, nor even found in the wild in China; as such we recommend avoiding that name. We chose the more descriptive name "oak-leaved thorn-apple".
