Buchnera americana B. S. Slaughter

A southern species of sandy open savanna and prairies, not collected in Michigan since the First Survey gathered it in Kalamazoo and Calhoun Cos. in 1838, although two sheets, dated 1843, in the D. Cooley collection (MSC), but without locality, may have come from Macomb Co. The species is still present in adjacent Lambton Co., Ontario.

The species is hemiparasitic on the roots of a great variety of trees and presumably other plants, but can mature without a parasitic attachment. The corolla is purplish to blue and nearly regular.
