✵The article gives records of the herb (21).Epilobium hohuanense S.S.Ying., 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 hohuanense S.S.Ying is classified in the Epilobium genus, of the Onagraceae family., it is also known as Hohuanense willow herb.
Epilobium hohuanense S.S.Ying is a perennial plant, stems are often decumbent, cylindrical, often purple-red, 5~20 cm high, 1~2 mm thick, branched or unbranched, surrounded by curly pilose, sometimes ridged. Leaves are opposite, alternate on inflorescence, narrowly elliptical or oblong to lanceolate, often spatulate (spoons-shaped) at the lower part of the stem, 0.5~2.5 cm long and 0.15~0.7 cm wide, apex is nearly sharp, the lower part of the stem is nearly blunt, base tapering to narrowly cuneate (wedge-shaped), edge with 4~10 teeth protruding on each side, lateral veins are inconspicuous. 3-6 strips on each side, nearly glabrous or with sparse hairs on the lower veins and edges, gradually changing into lavender; Petiole is 1~3 mm long, subsessile at the upper part of the stem.
The inflorescence is upright; Flowers are nearly upright; Bud is oval, 2~4 mm long, 0.4~0.8 cm in diameter; The length of the flower tube is 0.6~1.1 mm, the diameter is 1.2~1.6 mm, and the throat has a ring of sparse hairs or nearly glabrous; Sepals are green or purplish red, oblong, 2~3.5 mm long, 0.7~1 mm wide, villous, with white petals, often turning pink or rose, obovate, 3.5~6.5 mm long and 2.3~3.2 mm wide; The anthers are milky yellow, oblong, 0.5~0.9 mm long and 0.3~0.5 mm wide; The length of the outer filament wheel is 1.8~3.4 mm, and the length of the inner filament wheel is 1~1.8 mm; Style is 2.5~3.5 mm long, glabrous; Stigma is nearly capitate to broadly clavate, 0.6~1 mm long and 0.45~0.8 mm wide, surrounded by outer anthers when flowering. Calyx fruit is 2.6~5.5 cm long, villous or glabrous; the carpopodium (fruit stalk) is 0.9~2.2 cm long.
The seeds are oblong to narrowly obovate, 1~1.3 mm long, 0.36~0.46 mm in diameter, round at the top, with a short rostrum (beak), light brown and papillate on the surface; The tassel is white, 5~9 mm long, and not easy to fall off. Its flowering period is from July to September and fruiting from August to November.
Ecological environment: The plant grows in the wet place of the open rocky beach or gravel land on the hillside of 2,650~3,600 meters above sea level, or at the forest edge. The type specimen is collected from Hehuan Mountain at the junction of Hualien and Nantou in Taiwan.
This species Epilobum hohuanense S.S. Ying is similar to Epilobium platystigmatosum C. Robin., and it is easy to be mistaken for the latter. The main difference is that this species Epilobum hohuanense S.S. Ying is short, its leaves are short and wide, its seeds are large, and its tassels are not easy to fall off. It grows in the high mountain area of 2,650~3,600 meters, while the latter Epilobium platystigmatosum C. Robin. only grows in the middle and low altitude area of 1,100~2,500 meters.
