Epilobium sect:(8).Epilobium roseum Schreb.
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.
Botanical description: Epilobium roseum Schreb is classified in the Epilobium genus, of the Onagraceae family, it is also known as the long petiole willow herb, pale willowherb. Epilobium roseum Schreb is a perennial herb, upright, succulent nearly spherical overwintering scaly roots grow out at the base of the stem in autumn, scaly leaves are coriaceous, brown, with a residual stem at the base, wide obovate, 6~8 mm long and 4~6 mm wide, or gives birth to root sucker, thin crawling branches.

Capsular fruit is 4~6 cm, sparsely villous; the carpopodium (fruit stalk) is 0.6~1.5 cm long. The seeds are inverted egg-shaped, 1~1.2 mm long, 0.45~5.5 mm in diameter, with a short rostrum (beak) at the top, brown and there are papillates on the surface; The tassel is white, 4~6.5 mm long, and easy to fall off.
According to present classifications, there is one original subspecies of Epilobium roseum Schreb, its name is Epilobium roseum Schreber subsp. roseum, and one subspecies, its name is Epilobium roseum Schreber subsp. subsessile (Boiss.) P.H. Raven.
