Description
Hypericum suffruticosum is a perennial shrub.
“Usually glabrous herbs or shrubs. Leaves usually punctate, simple, opposite, entire, usually sessile or subsessile, exstipulate. Inflorescence basically cymose; flowers perfect, regular, bracteates, subsessile or short-pedicellate, sepals 2, 4, or 5, persistent; petals 4 or 5, usually marcescent, yellow or pink; stamens 5-numerous, separate or connate basally forming 3-5 clusters or fascicles, filaments usually persistent; carpels 2-5, stigmas and styles separate or fused, ovary superior, 1-locular or partly or wholly 2-5 locular, placentation axile or parietal. Capsules basically ovoid, longitudinally dehiscent, styles usually persistent; seeds numerous, lustrous, areolate, cylindric or oblong. In general our species form a polymorphic complex with many intergrading taxa.”[2]
"Small, usually decumbent shrub, 7-15 cm tall, stems wing-angled. Leaves oblong, elliptic, or slightly obovate, 1-8 mm long, 1-3 mm wide, obtuse, base jointed or notched. Flowers usually solitary, occasionally in cymules; bracts paired, basal; pedicels reflexed, 6-13 mm long. Outer sepals 2, ovate or widely elliptic, 5-9 mm long, 4.5-7 wide, acute, inner sepals usually absent; petals 4, obovate, 5-7 mm long; styles 2, usually separate, ca. 1.5 mm long, ovary 1-locular. Capsules ovoid or ellipsoid, ca. 3 mm long and 2 mm broad; mature seeds not seen."[2]
