Hypericum sect. Sampsonia is a small section of plants in the genus Hypericum. It comprises only two species, both endemic to eastern Asia: Hypericum sampsonii and Hypericum assamicum.[1][2][3]
They are perennial herbs, the stem bases sometimes becoming woody, growing up to 80 cm (31 in) tall.[1] They have black glands on the leaves, petals, anthers, and usually the sepals.[4] The leaves are opposite and perfoliate with entire margins. They have 5 sepals, 5 yellow petals, 3 styles, and numerous stamens.[4][5][6]
