Perennial, shrub, tree.
Stem: bark often peeling distinctively.
Leaf: simple or 0, generally cauline, alternate, opposite ( whorled), evergreen or deciduous, often leathery, petioled or not; stipules 0.
Inflorescence: raceme, panicle, cyme, or flowers 1, terminal or axillary, generally bracted; pedicel often with 2 bractlets.
Flower: generally bisexual, generally radial, bell-shaped, cylindric, or urn-shaped; sepals generally (0)4–5, generally free; petals generally (0)4–5, free or fused; stamens 8–10, free, filaments rarely appendaged, anthers awned or not, dehiscing by pores or slits; nectary generally present at ovary base, generally disk-like; ovary superior or inferior, chambers generally 1–5, placentas axile or parietal, ovules 1–many per chamber, style 1, stigma head- to funnel-like or lobed.
Fruit: capsule, drupe, berry.
Seed: generally many, winged or not.
± 100 genera, 3000 species: generally worldwide except deserts; some cultivated, especially Arbutus, Arctostaphylos, Rhododendron, Vaccinium. [Kron et al. 2002 Bot Rev 68:335–423] Monophyletic only if Empetraceae included, as treated here. Ledum included in Rhododendron. Non-green plants obtain nutrition from green plants through fungal intermediates. —Scientific Editors: Gary D. Wallace, Thomas J. Rosatti.
Perennial, non-green, glabrous to glandular-hairy; roots brittle, main often elongate.Key to Monotropa

Flower: sepals generally 5, free; petals generally 5, free, oblong-cup-shaped, ± bulged at base; stamens generally 10, included, anthers dehiscing by 1 or 2 slits, unawned; nectary lobes (8)10, ± clasping stamen bases; ovary superior, lines of dehiscence evident, chambers (4)5, placentas axile.
Fruit: capsule, loculicidal, erect, dehiscing tip to base.
Seed: many per chamber, fusiform.
2 species: n hemisphere. (Greek: 1 direction, from 1-sided inflorescence)
