Epilobium sect:(5).Epilobium palustre L.
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 palustre is a perennial upright herbaceous plant, slender creeping branches grow from under the base of the stem, 5~50 cm long, with pairs of leaves on sparse nodes, terminal succulent scaly buds, and the scale leaf turn brown the following year, and the stem grows from the base. The stem is 5~15 cm high, 0.5~5.5 mm thick, unbranched or branched, sometimes there are degenerated branches in the axils of the middle leaves, which are cylindrical and have no ridgelines, the periphery is covered with curly pilose, sometimes the lower part is nearly glabrous. Leaves are opposite, or alternate on inflorescence, nearly linear to narrowly lanceolate, 1.2~7 cm long, 0.3~1.9 cm wide, the apex is sharp or tapering, sometimes slightly blunt, the base is orbicular (subrotund) or cuneate (wedge-shaped), the margin is entire or with 5-9 inconspicuous teeth on each side, 3~5 lateral veins on each side, inconspicuous, lower veins and margin are sparsely villous or nearly glabrous; Petiole is absent or sparsely, 1~3 mm long.
Inflorescences are upright or slightly pendulous before blooming, densely covered with curved pilose, and sometimes mixed with glandular hairs. Flowers are nearly upright, the bud is oval, 2~3 mm long and 1.8~2.2 mm in diameter; Ovary is 1.6~3 cm long; Densely covered with curved pilose and sparse glandular hairs; The flower stalk is 0.8~1.5 cm long; The hypanthium (calyx tube) is 1~1.2 mm long and 1.3~2 mm in diameter, and the throat part is nearly glabrous or has a ring of sparse hairs; Sepals are oblong-lanceolate, 2.5~4.5 mm long, 1~1.2 mm wide, the apex is sharp, densely covered with villous and glandular hairs; Petals are white to pink or rose-purple, reversed cardioid, 3~9 mm long, 2~3 mm wide, apex concave depth is 0.8~1 mm; Anthers are oblong, 0.4~0.6 mm long and 0.2~0.4 mm wide; The length of the outer filament wheel is 2~2.8 mm, and the length of the inner filament wheel is 1.2~1.5 mm; Style is 1.4~3.8 mm long, upright, glabrous; Stigma is clavate to nearly cylindrical, 1~1.8 mm long, 0.4~0.7 mm in diameter, slightly protruding from the outer anther when flowering.
The capsularfruit is 3~9 cm long, villous; the carpopodium (fruit stalk) is 1~5 cm long. The seeds are prismatic to narrowly obovate, 1~2.2 mm long, 0.38~0.55 mm in diameter, with a long rostrum (beak) at the tip, 0.08~0.3 mm long, brown, and there are tiny papillae on the surface; The coma is gray-white or brown-yellow, 6~9 mm long, and does not fall off easily. Its flowering period is from June to August and fruiting from August to September.
Ecological environment: Epilobium palustre grows in lakes, marshes, river valleys, beside gullies, in the wet places of subalpine and alpine grasslands, in the area at altitudes of 200~2,500 meters in the north and 2,500~4,500 meters in the southwest. As the plant often grows in the marsh, so it is also known as marsh willow herb. The plant widely grows in the temperate and frigid regions of the Northern Hemisphere. It spreads near the Arctic in northern Asia, Bhutan, Sikkim, Nepal, northern Pakistan, Kashmir, West Caucasus and Black Sea, Europe, and North America. The plant grows in western, southwest, and northeast China.
