Hypericum socotranum is a species of flowering plant in the Hypericaceae family which is endemic to the island of Socotra in Yemen.[2] Its natural habitats are subtropical or tropical dry forests and rocky areas.[3]
The stem has internodes which are 4–16 mm (0.16–0.63 in) long. They are shorter than the leaves which are 12–24 mm (0.47–0.94 in) long and 5–10 mm (0.20–0.39 in) wide in an elliptic to oblanceolate shape. The leaves are acute or apiculate to obtuse and usually have one to three basal veins, though they can sometimes have five. Additionally, there are gland dots on the leaves which are visible on the dorsal surface.[3]
The inflorescence has only one flower with a pedicel that is 1–6 mm (0.039–0.236 in) long. The sepals are 5–6.5 mm (0.20–0.26 in) long and 2.5–3 mm (0.098–0.118 in) wide and are apiculate to obtuse. The flower petals are 15–30 mm (0.59–1.18 in) long and 9–15 mm (0.35–0.59 in) wide. The stamen fascicles are 8–12 mm (0.31–0.47 in) long. The ovary is ovoid-conic in shape, with coherent styles. The seed capsule measures 12–13 mm (0.47–0.51 in) long by 6–7 mm (0.24–0.28 in) wide.[3] The pollen grains of the species are all tricolporate, meaning they have three grooves in a roughly triangular layout.[4]
