✵The article gives records of the herb (3).Epilobium wallichianum Hausskn., its English name, Latin name, common names, property and flavor, its botanical source plant species, with a detailed introduction to the botanical features of this plant species, the growth characteristics, and ecological environment of this plant species.
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: The Epilobium wallichianum Hausskn., is a plant of the Epilobium L. genus, Onagraceae family (evening primrose family), it is commonly known as big flower willow herb, thin-leaf willow herb, etc. Its synonyms are Epilobium mairei, Epilobium tanguticum, Epilobium sykesii, Epilobium duclouxii, Epilobium souliei, Epilobium wallichianum subsp. souliei, etc.
Epilobium wallichianum Hausskn is a perennial upright herbaceous plant, often clustered, produces succulent scaly roots from the ground at the base of the stem, and brown scaly leaves persist at the base of the stem the following year. The stem is 10~70 cm high, 1.5~4 mm thick, often branched, or sparsely unbranched, the upper part is villous around, the lower part is glabrous, and only villous on the ridge line. Leaves are opposite, alternate on inflorescence, ovate, wide lanceolate on the upper part of the stem, sometimes obovate on the lower part of the stem, 2~7 cm long and 1.2~2.6 cm wide, the apex is nearly acuminate or tapered, rounded base, 15~20 sharp teeth on each side of the edge, 4~5 lateral veins on each side, and villous only on the veins and the edge; Petiole is 2~8 mm long at the lower part, absent at upper part.
Inflorescence is pendulous to suberect. Flowers are nearly upright; Buds are ovoid, 4~7 mm long; Ovary is 1.8~2.1 cm long, mixed with villous and glandular hairs; The flower stalk is 1~3 mm long; The length of the hypanthium (calyx tube) is 1~1.5 mm, the diameter is 1.8~3 mm, and the throat has a ring of white hairs; Sepals are nearly lanceolate, 4~7.5 mm long, 1~1.8 mm wide, covered with villous and glandular-hairy; Petals are fresh rose-purple, wide obovate to reversed cardioid, 7~16 mm long, 4~9 mm wide and the concave at the apex is 1.5~3 mm deep; Anthers are 0.8~1.1 mm long and 0.4~0.5 mm in diameter; The length of the outer filament wheel is 4.5~6.6 mm, and the length of the inner filament wheel is 0.3~5 mm; Style is upright, 4~9.5 mm long; Stigma is nearly capitate, 1.9~2.5 mm long and 1.6~3 mm in diameter. When flowering, it surrounds the outer anther or protrudes from the anther.
The capsularfruit is 3.5~7.5 cm, diameter is 1~1.5 mm, and sparsely villous; The carpopodium (fruit stalk) is 1~10 mm long. Seeds are narrowly obovate or oblong obovate, 1.2~1.5 mm long, 0.44~0.6 mm in diameter, short rostrum (beak) at the top, brown and papillose on the surface; The coma is white, 7~8 mm long, and easy to fall off. Its flowering period is from July to September and fruiting from August to October.
Ecological environment: Epilobium wallichianum Hausskn grows in wet places of gravel in valleys and gullies in mountainous areas, forests, shrubs, bamboo bushes, or wetlands along ditches, at altitudes of of 1,800-3,000 meters. The plant grows widely in China, it also grows along the Himalayas, Pakistan, Myanmar, Sikkim, Nepal, Bangladesh, and Bhutan in the western Himalayas. The above-ground parts are harvested in summer and autumn, drying in the sun or fresh use.
