Shrubs, decumbent, spreading and rooting, wiry, branches ascending to erect, forming compact mats, 0.5–4.5 dm. Stems: internodes 4-lined. Leaf-blades oblong or elliptic to obovate, 4–25 × 2–12 mm, base not articulated, cuneate, margins plane, apex rounded, midrib with 2–4 pairs of branches. Inflorescences 1 (–5) -flowered. Flowers 20–25 mm diam.; sepals persistent, not enclosing capsule, 5, broadly elliptic to elliptic-spatulate or obovate, subequal, 4–5 × 2.5–3 mm; petals 5, golden yellow, oblanceolate, 6–10.5 mm; stamens persistent, 100; ovary 3-merous. Capsules ovoid to ovoid-cylindric, 8–12 × 5 mm. Seeds narrowly to broadly carinate, 1.5–2 mm; testa finely foveolate-reticulate.


Phenology: Flowering early–mid summer (Jun–Jul).
Habitat: Seepage areas, moist rock crevices, ditches, road embankments
Elevation: 900–1600 m

Discussion

Hypericum buckleyi is found throughout the southern Appalachian Mountains.

The decumbent habit and persistent sepals and stamens distinguish Hypericum buckleyi from its nearest relative, H. prolificum.
