✵The article gives records of the herb (2).Epilobium parviflorum Schreber., 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 parviflorum Schreber is commonly known as small flower willow herb, hoary willow herb, etc. Epilobium parviflorum Schreber is a perennial stout herbaceous plant, it is upright, rosette-shaped leaf buds that grow from the base of the stem in autumn. Stems are 18~100 cm long, 3~10 mm thick, often branched at the upper part, mixed with long villous hairs and short glandular hairs at the periphery, gray villous hairs stretched at the lower part, and the downward ridge of the petiole is more or less obvious. Leaves are opposite, alternate at the upper part of the stem, narrowly lanceolate or oblong-lanceolate, 3~12 cm long and 0.5~2.5 cm wide, the apex is tapering, the base is round, there are 15~60 unequal fine teeth on each side of the margin, both sides are villous, 4~8 lateral veins on each side; Petiole is nearly absent or 1~3 mm long.
Racemes are upright, often branched; Bracts are leaflike. The flowers are upright, the buds are oblong and obovoid, 3~5 mm long and 2~3 mm in diameter; Ovary is 1~4 cm long, densely covered with upright short glandular hairs, sometimes mixed with a few villous hairs; Pedicel is 0.3~1 cm long; The length of the hypanthium (calyx tube) is 1~1.9 mm, the diameter is 1.3~2.5 mm, and there is a circle of long hair at the throat part; Sepals are narrowly lanceolate, 2.5~6 mm long, with carinate ridges on the back, covered with glandular hairs and villous hairs; Petals are pink to fresh rose-purple, pale white, wide obovate, 4~8.5 mm long, 3~4.5 mm wide, and 1~3.5 mm deep at the apex; Stamens are oblong, 0.5~1.3 mm long, 0.35~0.6 mm in diameter, the outer filament wheel is 2.6~6 mm long, the inner filament wheel is 1.2~3.5 mm long; Style is upright and 2.6-6 mm long, white to pink, glabrous; Stigma is deeply 4-parted, lobes are oblong, 1~1.8 mm long, upright at first, bent back later, nearly as long as stamens.
The capsularfruit is 3~7 cm long, with the same coating hairs as hairs on the ovary; The carpopodium (fruit stalk) is 0.5~1.8 cm long. The seeds are inverted ovoid, 0.8~1.1 mm long, 0.4~0.5 mm in diameter, round at the top, with a very inconspicuous rostrum (beak), brown, and rough papillae on the surface; The tassel is 5~9 mm long, dark gray or off-white, and easy to fall off. Its flowering period is from June to September and fruiting from July to October.
This species is similar to Epilobium hirsutum, the difference is: that the leaves are somewhat short-stalked, and the base does not hold the stem; Flowers are smaller, petals are 5~8 mm long; The pistil is as long as the outer stamens, and the overwintering rosette buds have no crawling branches.
Ecological environment: Epilobium parviflorum grows on hillsides, watersides, or roadsides in the area at altitudes of 800~2000 meters. Epilobium parviflorum spreads in Asia, Europe, and other places. In China, it grows in the northwest, north area, and the upper and middle reaches of the Yangtze River. In Asia, it spread as from China to Western Asia, Afghanistan, Cyprus, Iran, Iraq, Israel, Jordan, Lebanon, Syria, Turkey, Caucasus: Armenia, Azerbaijan, Georgia, Nepal, Pakistan. In Europe, it spread as to Northern Europe: Denmark, Finland, Ireland, Norway, Sweden, United Kingdom, Middle Europe: Austria, Belgium, Czechoslovakia, Germany, Hungary, Netherlands, Poland, Switzerland, East Europe: Belarus, Estonia, Latvia, Lithuania, Ukraine, Southeastern Europe: Albania, Bulgaria, Greece, Italy, Malta, Romania, Yugoslavia. Southwestern Europe: France, Portugal, Spain. In Africa, it spread to Macaronesia: Azores, Madeira Islands, Canary Islands, Northern Africa: Algeria, Morocco, Tunisia.
