Epilobium kermodei Raven

Most populations of this species were earlier determined as Epilobium tanguticum (E. wallichianum in this treatment), prior to Raven’s study of the genus in the Himalayan region.

Herbs perennial, robust, erect, with fleshy stolons 1-12 cm, extending underground and terminating in thickened buds. Stems 40-120(-200) cm tall, simple or sparsely branched, densely glandular and strigillose throughout, with faint raised strigillose lines decurrent from margins of petioles. Leaves subsessile above, lower ones with petioles 1-6 mm; cauline blade narrowly ovate to lanceolate, 3.5-8(-11) × 1.5-4(-4.5) cm, subglabrous with densely strigillose margin and midvein, base broadly cuneate to subrounded, margin sharply serrulate with 28-42(-60) teeth per side, apex acute. Inflorescence erect, congested; flowers erect. Sepals 5-8 mm. Petals rose-purple, 7-15(-18) mm. Stigma capitate to broadly clavate, entire. Capsules 7-11 cm, strigillose, glandular; pedicels 0.7-1.5 cm. Seeds dark brown, 0.8-1.2 mm, coarsely papillose, with short chalazal collar; coma white, detaching easily. Fl. May-Aug, fr.
