Minuartia godfreyi
Rhodora 82: 498. 1980.
Plants short-lived perennial or winter-annual. Taproots filiform. Stems erect or ascending, arising from mats of slender, prostrate or ascending, wintering stems, green, 10–40 cm, occasionally stipitate-glandular at nodes, internodes of all stems 1–3 times as long as leaves. Leaves sometimes overlapping proximally, connate proximally, with ± loose, herbaceous sheath 0.2–0.4 mm; blade widely spreading to erect, green, 1-veined abaxially, flat, narrowly elliptic (proximal petiolate blades) to linear (remaining cauline blades), 8–30 × 0.5–3 mm, flexuous, margins not thickened, scarious, occasionally stipitate-glandular, apex green, acute to acuminate, shiny, glabrous; axillary leaves absent. Inflorescences 3–5 (–7) -flowered, open, leafy cymes; bracts linear to lanceolate, herbaceous. Pedicels 1–5 cm, sparsely glandular. Flowers: hypanthium disc-shaped; sepals 3-veined, lanceolate (herbaceous portion linear-lanceolate to lanceolate), 3.5–5 mm, not enlarging in fruit, apex often purple, acute, not hooded, stipitate-glandular; petals oblong-spatulate, 2.5–3 times as long as sepals, apex rounded, shallowly notched. Capsules on stipe ca. 0.2 mm, ovoid, 4 mm, shorter than sepals. Seeds black, suborbiculate to reniform, radicle obscure, laterally compressed, 0.6–0.8 mm, muriculate-papillate.
Phenology: Flowering spring.
Habitat: Open mesic meadows, seeps, and stream banks
Elevation: 0-400 m
Distribution
Ala., Ark., Fla., Ga., N.C., S.C., Tenn., Va.
Discussion
Of conservation concern.
Minuartia godfreyi is known from few, very widely scattered populations; it may be most closely related to M. patula and M. muscorum, sharing prominently ribbed sepals with both taxa and black, muriculate-papillate seeds with the latter (R. Kral 1983).
