Heuchera richardsonii R. Br.
Common Name: PRAIRIE ALUM ROOT
Coefficient of Conservatism: 8
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Nt P-Forb

Dry prairies and sandy river banks, rocky ground, oak savanna, rarely in lowland forests.

The flowers are quite bilaterally symmetrical, the upper lobe of the perianth nearly twice as long as the lower side; and the stamens (including anthers) are exserted less than 2 mm beyond the upper side of the perianth, or less than half its length. The larger and more bilaterally symmetrical flowers, longer calyx lobes, and less exserted stamens usually separate this species from H. americana. The stamens are strongly exserted in H. americana, usually protruding beyond the longest calyx lobe by 60% or more the length of the perianth.
