Hypericum buckleyi, known as Blue Ride St. John's wort and Buckley's St. Johnswort, is a rare species of flowering plant in the family Hypericaceae found only in the Appalachian Mountains of the southeastern United States.^[1][2] The species is listed in the state of Georgia (S1), South Carolina (SX), and North Carolina (S3).^[3]

Description

Buckley's St. Johnswort is a small shrub, growing up to 45 cm (18 in) tall and spreading to form low, compact mats. It has peeling, reddish stems with thin bark. The oblong or oblanceolate leaves are sessile or subsessile, up to 25 mm (0.98 in) long and 12 mm (0.47 in) broad. The species typically flowers in early July, typically they only produce one blossom per flowerhead, but there may be up to 5.^[4] The flowers are 20–25 mm (0.79–0.98 in) across with 5 golden yellow petals, becoming reflexed with age. The ovaries have three parts, forming narrowly ovoid to cylindric capsules.^[2]

Distribution and habitat

Hypericum buckleyi has a limited range, known only to occur at 900–1,560 m (2,950–5,120 ft) in northeastern Georgia, northwestern South Carolina, and southwestern North Carolina.^[1] A montane species, they are most often found on rock outcrops, barrens, glades and balds.^[5] Though their habitat can include wetter areas such as seeps and moist crevices as well.^[2]
