a genus of evergreen shrubs of the family Ericaceae. The flowers have a pink ovate-urceolate or globose-urceolate corolla and are gathered into an umbel. The fruit is a capsule. There are one or two species, distributed in the northern hemisphere. In the USSR there is one species, the marsh andromeda (A. polifolia), which has leathery lanceolate leaves. The marsh andromeda grows in the forest and tundra zones in swamps and damp coniferous forests. The leaves contain a poisonous glycoside that is dangerous to sheep and goats.
