Introduction of Epilobium Herb in Epilobium sect:(6).Epilobium minutiflorum Hausskn.
✵The article gives records of the herb (6).Epilobium minutiflorum 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: Epilobium minutiflorum Hausskn is a perennial upright herbaceous plant, it is classified in the Epilobium genus, of the Onagraceae family. The stem is 15~100 cm tall, 2~8 mm thick, multi-branched, sparsely unbranched, and its surroundings are densely villous, and its lower part is often nearly glabrous, sometimes with two inconspicuous ridges. Leaves are opposite, alternate on inflorescence, oblong-lanceolate to narrowly ovate, 2~7 cm long and 0.4~1.7 cm wide, the apex is nearly blunt or sharp, the base is cuneate or orbicular (subrotund), margin with 20-41 sawteeth on each side, lateral veins with 4-7 sawteeth on each side, raised, villous on veins and margin, and other parts are glabrous; Petiole is 1~6 mm long, the upper part is proximal subsessile.
The inflorescence is slightly pendulous before flowering, covered with gray-white pilose and sparse glandular hairs. Flowers are upright; Buds are spherical to ovoid, 2~3 mm long and 1.5~2.5 mm in diameter; Ovary is 1.5~4 cm long, densely covered with gray-white pilose and sparse glandular hairs; The flower stalk is 0.4~1.5 cm long; The length of the flower tube is 0.8~1.2 mm, the diameter is 1.2~1.4 mm, and the throat has a ring of sparse long hair; Sepals are oblong-lanceolate, 2.4~4 mm long, 0.7~1.2 mm wide, slightly carinate (cariniform), with sharp apex; Petals are white, pale pink or rose-red, oblong, rhombic or obovate, 3~5 mm long and 1.2~2 mm wide, the concave depth of the apex is 0.5~1 mm, and the anthers are oblong and lanceolate, with a length of 0.4~0.8 mm and a diameter of 0.2~0.3 mm; The length of the outer filament wheel is 1.5~2.5 mm, and that of the inner filament wheel is 1~2 mm; Style is upright, 1.4~2.5 mm long, glabrous; Stigma is clavate, sparsely capitate, 0.7~1.5 mm long, 0.8~1.1 mm in diameter, surrounded by outer anthers when flowering.
The capsular fruit is 3~8 cm long, and is covered with sparsely curved pilose or glabrous; The carpopodium (fruit stalk) is 0.5~2 cm long. The seeds are narrowly obovate, 0.8~1.2 mm long and 0.38~0.48 mm in diameter, with a long transparent rostrum (beak) at the top, the surface is brown and has fine papillae; The tassel is white, 5~7 mm long, and easy to fall off. Its flowering period is from June to August and fruiting from July to October. For its seed are thin, it is also known as the Thin-seed willow herb.
This species is easily distinguished from other species because of its curly hair cover around the stem, small flowers, and long rostrumss (beaks) at the top of the seed. This species is widely distributed, and the shape of stem indumentum and stigma varies greatly.
Ecological environment: Epilobium minutiflorum Hausskn grows in wetlands, ditches, rivers, river beaches, lakes and ponds, hillside meadows, watersides, fields, streams, and marshes, valleys, wet places on barren slopes in the middle and low mountain areas at altitudes of 500~1800 meters.
Epilobium minutiflorum Hausskn widely spread in Central Asia to the Himalayas, Kyrgyzstan, Kazakhstan, Uzbekistan, Kashmir, Afghanistan, Iran, Caucasus, Turkey, Asia Minor, etc. In China, it is mainly distributed in the west north, and west south areas of China.
