Inflorescence: scapose, flower generally 1. Flower: bisexual, radial, nodding; sepals 5 [4–6], generally free; petals 5 [0]; stamens many; pistil 1, ovary superior, chambers generally 5, incomplete above or not, placentas generally axile, style 1, 5-lobed, umbrella-like or not, stigma terminal or under tips of style lobes. Fruit: capsule, loculicidal; valves generally 5. Seed: many, flattened-ovoid, smooth, or club-like, papillate [winged].
3 genera, 24 species: northern California, Oregon, British Columbia, eastern North America, northern South America, especially acidic bogs, streamsides, moist areas; often planted outside native ranges by horticulturists but generally not invasive.
