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 anagallidifolium Lam., a dwarf perennial herb, it is classified in the Epilobium genus, of the Onagraceae family, shoots grow from leafy roots on the ground at the base of the stem. Stems are often clustered, ascending or nearly upright, 3~22 cm high, 0.5~1 mm thick, sometimes slender and sparse, or thick and dense with leaves, nearly glabrous or ridged, with sparsely villous and glandular hairs on the edges. Leaves are opposite, alternate on inflorescence, dense in the lower part of the stem, but sparse in the upper part, spatulate (spoons-shaped) to oblong in the lower part of the stem, oval to lanceolate in the upper part of the stem, 0.8~2.5 cm long and 0.25~1 cm wide, blunt in the lower part of the stem at the apex, subacute in the upper part of the stem, narrow or cuneate (wedge-shaped) at the base, with nearly entire margin to a few distant odontoid processes, and 2~4 lateral veins on each side, not obvious, nearly glabrous or with sparse soft hairs on veins of the back surface. The petiole is 1~6 mm long or subsessile at the upper part.
The inflorescence consists of a few flowers, drooping at the beginning, then becoming nearly upright. Flowers are nearly upright; Buds are elliptic, 2~5 mm long; Ovary is often reddish, 6~20 mm long. Glabrous or sparsely villous and glandular-hairy; The flower stalk is 1~6 mm long, even 15 mm long; Flowers are 0.6~1.2 mm long and 0.8~1.8 mm in diameter, nearly glabrous; Sepals are green or reddish, lanceolate, 1.5~5 mm long, 0.6~1.5 mm wide, subglabrous to with sparse glandular hairs; Petals are pink to rose-purple, pale white, narrowly cordate, 2.5~6.5 mm long, 1.6~3.5 mm wide and 0.6~1.2 mm deep concave at the apex; Anthers are nearly oblong, 0.35~0.6 mm long and 0.25~0.4 mm in diameter; The silk is milky yellow to reddish, the length of the outer wheel is 1.4~3.2 mm, and the length of the inner wheel is 0.7~2 mm; Style is upright, 1.2~2.5 mm long; Stigma is clavate, sparsely capitate, 0.9~1.5 mm long, 0.4~0.7 mm in diameter, surrounded by outer anthers when flowering.
The capsular fruit is 1.7~3.6 cm long, 0.1~0.2 cm in diameter, slender, often reddish purple, nearly glabrous or covered with sparsely short hairs; The carpopodium (fruit stalk) is 1~3.5 cm long. The seeds are oblong, obovate, 0.7~1.4 mm long, with a short rostrum (beak) at the top, light brown, fine reticulation on the surface, and sparse shallow papillae; The tassel is gray, 1.5~4 mm long, and persistent. Its flowering period is from July to August and fruiting from August to September.
Ecological environment: Epilobium anagallidifolium Lam grows in the wet place of the gully gravel, ridges or ledges, shores of rivers or lakes in the mountainous area at an altitude of 1,300~1,500 meters. In China, it spreads in the Altai mountain area of Xinjiang. This species is widely spread in mountainous areas of Europe and North America, and also distributed in the Kamchatka Peninsula of Asia, and Siberia. As it mainly grows in alpine or subalpine zones, it is also known as the Alpine willow herb. The herb is also known as Pimpernel willow herb, Alpine willowweed, etc.
