乌苏里荨麻 wu su li qian ma

Urtica cyanescens Komarov ex Jarmolenko in Komarov, Fl. URSS 5: 714. 1936.

Stipules all free; leaf blade blue-green when dry, broadly ovate or ovate, thin membranous, outer secondary veins often reaching teeth, base broadly cuneate or rounded; cystoliths linear or botuliform; achene narrowly ovoid, apex acute, smooth, persistent perianth lobes densely setulose. Fl. Jul-Aug, fr. Aug-Sep.

Moist places in Pinus or mixed forests, river banks; 100-1000 m. Heilongjiang, E Jilin, E Liaoning [N Korea, Russia (Far East)].

Dmitry Geltman (pers. comm.) believes that Urtica cyanescens is a pure synomym of U. laetevirens. If an extremely narrow species concept were adopted, U. cyanescens could be separated from U. laetevirens, but then it would be necessary to treat U. laetevirens as an endemic of Hokkaido, Japan, from where it was described.
