Species from Lake Baikal, Russia, with finely divided leaves and erect stems of deep blue flowers. Unfortunately flowering tends to last only a few weeks and does not repeat. As the name suggests, from the area around Lake Baikal, where it does intergrade with Geranium pratense. The genus name is derived from the Greek (crane). The English name Cranesbill derives from the appearance of the fruit capsule of some of the species.
