Sabatia dodecandra
Sabatia foliosa
There are historical records of Sabatia dodecandra from Connecticut and New York. Reports from west of the range given here have been based on a concept of the species that included S. foliosa.

Sabatia foliosa has often been treated as a variety of S. dodecandra. Its recognition at specific status follows R. L. Wilbur (1970b) and J. D. Perry (1971). As the internodes of S. foliosa are generally less than 1.25 times as long as, and often shorter than, the subtending leaves, whereas those of S. dodecandra are mostly 1.25–3.5 times as long, this species has a more leafy appearance than S. dodecandra. The leaves of S. foliosa are thinner in texture than those of S. dodecandra; the apices of the mid-stem leaves of S. foliosa are usually obtuse and those of the distal leaves merely subacute, whereas the apices of the mid-stem and distal leaves of S. dodecandra are usually acute; and the corolla lobes of S. foliosa are proportionately narrower than those of S. dodecandra (M. L. Fernald 1902; Wilbur 1955). Because of its stoloniferous habit, S. foliosa often forms dense colonies, which S. dodecandra does not. Natural hybrids between these taxa are unknown, and artificial hybrids are sterile (Wilbur 1970b; Perry).
