Discussion

The flowers of var. virginianum are usually slightly smaller than those of var. pusillum and otherwise very similar. The name virginianum indicates the main area of occurrence, and this is the only variety found in the tidewater area, where it is frequent around Williamsburg. It can also be found in the Delmarva Peninsula.
