Nomenclatural Notes
Status: pro syn. of Q. rubra var. runcinata A.DC
Remarks
Engelmann remarked: “Q. runcinata was the name given to a form I found in the richest Mississippi bottom-lands opposite St. Louis, together with rubra, imbricaria, and palustris. From its smaller and narrower, coarsely dentate, not lobed leaves, and its smaller fruit, it seemed distinct enough from rubra, and was possibly a hybrid of it and some other small-fruited allied oak. But the leaves of rubra are so variable in size and outline that De Candolle (l. c. 60) was right in considering it a variety of rubra.”
