Sabatia macrophylla
Sabatia foliosa
large-leaf sabatia, largeleaf rose gentian
leafy marsh-pink or rose-gentian
several, clustered, terete, 5–14 dm, branching opposite throughout.
several–many, scattered or loosely clustered, terete or distally 4-ridged but not angled or winged, 0.8–7(–10) dm, branching generally all or mostly alternate, rarely all opposite.
all cauline at flowering time;
blade lanceolate to ovate-oblong or ovate, 2.5–6(–8.5) cm × 5–30(–45) mm.
basal absent at flowering time, internodes between cauline leaves generally less than 1.25 times as long as subtending leaves;
blade ovate-lanceolate to elliptic or linear, 1.5–6 cm × 4–14(–20) mm.
corymboid dichasia of compact cymules;
pedicels 1–5 mm.
open, few-flowered monochasial cymes or solitary flowers at ends of branches;
pedicels 10–70(–100) mm.
5-merous;
calyx tube campanulate, 1–2 mm, mid- and commissural veins about equally prominent, not ridged or with low, narrow ridges, lobes triangular to linear-subulate, 0.1–3 mm;
corolla white or cream throughout, tube 2–4 mm, lobes oblong-oblanceolate, 4–7(–9) × 2–3(–4) mm, apex rounded to obtuse;
anthers recurving.
7–12(–14)-merous;
calyx tube shallowly campanulate, 1.5–4 mm, mid- and commissural veins about equally prominent, 4-ridged;
lobes linear to narrowly spatulate or ± foliaceous, 10–20 mm;
corolla purplish pink or rarely white, eye yellow, projections of eye into corolla lobes oblong, sometimes shallowly 3-lobed, usually with a red border, tube (3–)4–8 mm, lobes oblanceolate to narrowly spatulate-obovate, 12–30 × 3–10 mm, apex rounded to subacute;
anthers coiling circinately.

Sabatia macrophylla
Sabatia foliosa
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.

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).
