Description
Hypericum balearicum is a shrub or small tree 0.6–2 m (2 ft 0 in – 6 ft 7 in) tall, usually forming a rounded bush with erect or ascending branches. Its stems are glandular and warty, yellow-green when young, becoming reddish-brown as it ages. The leaves are sessile, up to 15 mm (0.59 in) long and 7 mm (0.28 in) broad. The leaves have rounded tips, undulate margins, and broadly cuneate to rounded bases. They are leathery, with prominent warty glands, and paler underneath. The flowers are 15–40 mm (0.59–1.57 in) across with 5 golden yellow petals (rarely pale yellow), rounded sepals, with involucre-like bracts. The petals are oblong with rounded tips, 10–20 mm (0.39–0.79 in) long, and 4–9 mm (0.16–0.35 in) across.[2]
Its warty stems and leaves and its involucre-like bracts distinguish it from other species of Hypericum.[2]
