Habit: Perennial herb from caudex or rhizome, generally +- hairy. Stem: often +- leafy on proximal 1/2, rarely trailing and leafy throughout. Leaf: generally simple, basal and/or cauline, generally alternate, generally petioled; veins +- palmate. Inflorescence: raceme or panicle, generally +- scapose. Flower: generally bisexual, generally radial; hypanthium free to +- fused to ovary; calyx lobes generally 5; petals generally 5, free, generally clawed, generally white; stamens 3, [4], 5, 8, or 10; pistils 1 (carpels +- fused, ovary lobed, chambers 1 or 2, placentas generally 2(3), axile or parietal or occasionally proximally axile and distally marginal in ovary lobes) or 2 (carpels free, placentas marginal), ovary nearly superior to inferior, occasionally more superior in fruit, styles generally 2(3). Fruit: capsule (generally 2(3)-beaked, valves generally 2(3), generally equal) or 2 follicles. Seed: generally many, small.
Genera In Family: +- 30 genera, 600 species: especially northern temperate, arctic, alpine; some cultivated (Bergenia, Darmera, Heuchera, Saxifraga, Tellima, Tolmiea).
