Slender Yellow Woodsorrel (Oxalis dillenii Jacq.)

USDA PLANTS and BONAP both treat Oxalis florida Salisb. as a synonym of this species, and do not recognize any sub-taxa. However, POWO and FSUS both separate that as a species. Because few sources separate these taxa, we have had trouble building a range map.

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.
