Erect perennial herb, sprouting from the base or forming leafy basal rosettes; stem 10-75 cm tall, well-branched, with raised strigillose lines decurrent from the margins of the petioles, dense strigillose throughout or only above, then glabrescent below, rarely with glandular hairs on inflorescence. Leaves 2-8 x 0.5-2.3 cm, oblong-lanceolate, glabrous except for strigillose margins and veins, margins serrulate, apex subacute, cuneate base, subsessile. Inflorescence erect, dense canescent, rarely mixed with glandular hairs. Sepals 2.5-3 mm long, white-canescent. Petals 3-4.5 mm long, white to pale pink. Style 1.8-2.2 mm. Stigma clavate, surrounded by anthers at anthesis. Capsules 3.5-6 cm long, on pedicels 1-2.1 cm long. Seeds 0.8-1.1 x 0.32-0.42 mm, obovoid or narrowly so, papillose, the chalazal collar rather inconspicuous, 0.02-0.06 mm long; coma 4-5.5 mm, dingy white, deciduous.

Although a distinctive species by virtue of its minute flowers and white-canescent ovaries, E. minutiflorum is quite variable, and often similar in aspect to E. cylindricum, with which it is most often confused. Because it grows in a wide range of habitats, and extends particularly into lower elevations than most Epilobium in the region (including several collections from Baluchistan), E. minutiflorum has a longer growing season than other species. Fl. Per.: May-Oct. Fr. Per.: Jun-Nov; Distribution: Central Anatolia in Turkey eastwards to Kumaun in the Himalaya.
