Bog herbs, with tufted basal leaves clothed with glandular hairs which secrete a fluid that entraps insects, and scapose racemose flowers. Calyx-tube short, free from the ovary, very deeply 4-8-parted (commonly 5-parted). Petals usually 5, spatulate. Stamens as many as the petals; anthers short, extrorse. Ovary 1-celled; styles 2-5, usually 3, distinct or united at the base, often deeply 2-parted so as to appear twice as many, or fimbriate. Capsule 3-valved (rarely 5-valved), many-seeded, generally stipitate in the calyx. [Name from the Greek, dew, in allusion to the dew-like drops exuded by the glands of the leaves.]
