Ranunculaceae : Aquilegia canadensis

Aquilegia canadensis is a perennial herb growing 30 to 100 cm tall from a stout caudex. The stems are hollow, smooth to covered with small glandular hairs towards the tops. Stems come from clusters of ternate basal leave and have alternate biternate (occasionally triternate) leaves on the flowering stems. The individual lobes are wedge-shaped and shallowly to deeply lobed. The showy flowers are nodding, regular, 2-5 cm long from tips of the stamens to the ends of the spurs and 1.7-4.3 cm wide. Five rose to dull red colored sepals, 0.9-2 cm long alternate with 5 petals, that are red toward the base and yellowish on the upper parts. The base is formed into a narrow spur that is slightly enlarged at the tip and measure 2-3.6 cm long from the end of the spur to the opening at the upper end. The stamens are numerous and exerted from the corolla. There are 5 carpels that mature into 5 follicles, 1.2-3 cm long with a styler beak that is 0.9-1.8 cm in length and contain several small black seeds. Flowers bloom from April to June. The plants grow in moist soils in wooded areas in several eastern and western counties in South Dakota.
