Thanks, everybody, for the interesting discussions. Just to put on record the various sources involved, Flora of China gives the following difference between the two: 7 (6) <http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=134249#KEY-1-6> Plants often with dense stinging and setose hairs; leaf blade ovate or lanceolate, base cordate; petiole 1/6-1/2 as long as leaf blade. 9 *U*. *dioica* <http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=220014002> + Plants with sparse stinging and setose hairs; leaf blade lanceolate to linear, base rounded or notched; petiole 1/15-1/5 as long as leaf blade. 8 *U*. *angustifolia* <http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200006430> Based on this, the plants looks more closer to *Urtica angustifolia *Fisch. ex Hornem. However, neither Flora of China <http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200006430> nor Catalogue of Life <http://www.catalogueoflife.org/col/details/species/id/77bb85c565b05a352ad19096e912fb44> gives its distribution in India. Flora of China <http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200006430> says the species is similar to *Urtica* *dioica* in having dioecious plants, paniculate inflorescences, and similar stipule and achene features; however, it differs in having sparser stinging hairs, narrower leaves with a rounded base, and much shorter petioles. The taxa could either be sister species, or *U*. *angustifolia* could be an eastern geographical vicariant of *U*. *dioica*. It gives its distribution as China (Moist places in forests, thickets, stream banks; 800-2200 m. Hebei, Heilongjiang, Jilin, Liaoning, Nei Mongol, Shandong, Shanxi); Japan, Korea, Mongolia, Russia (Far East, Siberia).
