Epilobium sect:(29).Epilobium fangii.
Introduction: Epilobium sect is a section in the Epilobium genus of the Onagraceae family (evening primrose family), perennial herbs, upright, ascending, or prostrate. Stems are cylindrical or quadrangular. Leaves are opposite (occasionally whorled) at least below inflorescence and alternate sparsely spirally (E. sinense H. Lev.). Flowers are actinomorphic, parallel to the stem axis when blooming; flower tube exists; petal apex is concave to deeply 2-lobed; stamens vary in length in 2 whorls, pollen grains are yellow, pollinated by quadruple pollen; style is always upright; stigma is usually entire, clavate to capitate, as long as or higher than stamens, sometimes 4-lobed and higher than stamens.
