18. Epilobium amurense Haussknecht, Oesterr. Bot. Z. 29: 55. 1879.
Herbs perennial, erect, with leafy basal soboles, elongated rosettes, or rarely fleshy stolons. Stems (10-)20-150 cm tall, simple or branched, densely strigillose, often mixed with glandular hairs on upper parts, with 2(or 4) ± distinct raised strigillose lines decurrent from margins of petioles, or rarely subglabrous throughout. Leaves subsessile or petioles 1-6 mm; cauline blade ovate to narrowly so, or rarely lanceolate-oblong, 2-9.5 × 0.5-2.5 cm, subglabrous with strigillose margin and veins, base rounded or cuneate, margin serrulate or denticulate with 6-35 teeth per side, apex acute or acuminate. Inflorescence and flowers erect to slightly nodding. Sepals 3.5-6 mm, often keeled. Petals white, pink or rose-purple, 4.5-8(-10) mm. Stigma capitate or broadly capitate, entire. Capsules 1.5-7 cm, sparsely strigillose or rarely glabrous; pedicels 0.3-1.3 cm. Seeds brown, 0.8-1 mm, coarsely papillose, with short chalazal collar; coma dull white, readily detached. 2n = 36.

Herbs perennial, erect or ascending, with fleshy soboles that leave loose brown basal scales. Stems 15-90 cm tall, simple or branched, strigillose throughout, sometimes mixed with glandular hairs on inflorescence, lacking raised decurrent lines. Leaves subsessile or petioles to 4 mm; cauline blade broadly ovate to broadly lanceolate-elliptic, 1.5-5(-8) × 0.5-2.2(-3) cm, subglabrous with strigillose margin and midvein, base subcordate to cuneate, margin sharply denticulate with 7-22 teeth per side, apex subobtuse to acute. Inflorescence and flowers erect to slightly nodding. Sepals 4.5-6.5 mm, keeled. Petals pink to rose-purple, 7-11 mm. Stigma clavate or broadly so, entire. Capsules 3.5-7 cm, strigillose, often glandular; pedicels 0.4-1.5 cm. Seeds dark brown, 0.9-1.1 mm, coarsely papillose, with short chalazal collar; coma white, detaching easily. 2n = 36.
Based on the above, I will go for Epilobium amurense Haussknecht, Oesterr.
