Broad-leaved Toothwort is uncommon on the Allegheny Plateau of Garrett County, and becomes rare in the Ridge and Valley and Piedmont. Broad-leaved Toothwort is found in rich mesic forests.

Broad-leaved Toothwort is very similar to Slender Toothwort and Cut-leaved Toothwort. Broad-leaved Toothwort can be differentiated from Cut-leaved Toothwort by having basal leaves while in bloom. Cut-leaved Toothwort typically lacks basal leaves while in bloom. Slender Toothwort and Broad-leaved Toothwort are very similar in appearance. The best way to differentiate between these two species is to look at the stem (cauline) leaves. The cauline leaves of Broad-leaved Toothwort are similar in width to the basal leaves, while the cauline leaves of Slender Toothwort are much narrower than the basal leaves.

It is very important when documenting Broad-leaved Toothwort that the cauline leaves are well represented.
