Krigia biflora (Walter) S. F. Blake
Coefficient of Conservatism: 5
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Nt P-Forb

Savannas, especially oak or jack pine, sometimes spruce, often in moist ground and on banks and borders; fens, wet meadows.

The pappus bristles are much more numerous than in K. virginica, and in both they are strongly antrorse-scabrous. All of our specimens from the Upper Peninsula have gland-tipped hairs at the base of the involucre and on the pedicel below it. None of the Lower Peninsula specimens bear such glands. This entity has been recognized as the Great Lakes region endemic subsp. glandulifera (Fernald) Iltis. A single somewhat out of range collection by O. A. Farwell (1123b, BLH) from Keweenaw Co., lacks glands, and is not mapped as we strongly suspect a mix-up in labeling.
