Discussion

Varieties 2 (2 in the flora).

The inflorescences of Sabatia macrophylla are nearly flat-topped and usually contain more flowers than those of other Sabatia species. The relatively small, closely spaced flowers give this species a distinctive aspect. It further differs from S. difformis in its glaucous stems and leaves.

Sabatia macrophylla is restricted to central and southern Georgia, northern Florida, and southern Alabama, Louisiana, and Mississippi, mostly but not exclusively (in Georgia) near the Gulf Coast. The range of var. macrophylla extends farther west than that of var. recurvans.
