Geranium maculatum L.
Coefficient of Conservatism: 4
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Nt P-Forb

Usually in rich deciduous forests, especially in moist sites such as streamsides, pond borders, wet hollows, and swamps; less often in upland oak-hickory forests.

Records from Delta and Houghton Counties in the Upper Peninsula are from disturbed habitats; along railways and at a brushy woods edge in a Forestry Camp respectively. The Gogebic and Menominee Co. records are from more natural settings. .

Plants with white flowers are rare [f. albiflorum (Raf.) House]. A white-flowered form of a Eurasian species, G. pratense L., was collected along a driveway in Ann Arbor, Washtenaw Co., in 1954, but its status, whether truly escaped or not, is doubtful. It resembles G. maculatum, but the pedicels (and outer sepals) bear dense gland-tipped hairs. Geranium pratense is known as an escape in southern Ontario.
