Flowers usually solitary, occasionally twos or threes, 4-5 cm across. Fruit ovoid or pear-shaped, with a pronounced neck, up to 2 cm long by 1 cm wide, crowned by the erect sepals. Illustration.
Range: circumboreal and southward along the Rocky Mountains to Colorado and New Mexico. Widespread and common across Britich Columbia east of the Coast Range.

Leaflets biserrate with fine gland-tipped teeth; flowers 20-35 mm across, solitary or in small clusters, deep rose-coloured; sepals triangular without appendages, deciduous after flowering. Fruit ovoid to almost spherical with no calyx when rip. Illustration.
