Discussion

Plants of Halesia diptera occurring in the easternmost part of the range often possess larger corollas. These plants have been recognized as var. magniflora. Corolla size varies continuously with longitude and therefore the recognition of varieties is not warranted.

"lengthofcorolla" is not declared as a valid unit of measurement for this property.
