Gary D. Wallace, except as specified

Perennial, shrub, tree
Stem: bark often peeling distinctively
Leaves simple, generally cauline, alternate, opposite, rarely whorled, evergreen or deciduous, often leathery, petioled or not; stipules 0
Inflorescence: raceme, panicle, cyme, or flowers solitary, generally bracted; pedicels often with 2 bractlets
Flower generally bisexual, generally radial; sepals generally 4–5, generally free; petals generally 4–5, free or fused; stamens 8–10, free, filaments rarely appendaged, anthers awned or not, dehiscent by pores or slits; nectary generally at ovary base, 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

Subfamilies Monotropoideae, Pyroloideae, Vaccinioideae sometimes treated as families. Nongreen plants obtain nutrition from green plants through fungal intermediates.

Inflorescence: raceme or flowers solitary; emerging from soil nodding, erect in fruit, persistent after seed dispersal, bracted; bractlets 1–2; pedicels generally recurved to spreading when anthers open, erect in fruit, jointed to flower
Flower: sepals generally 5, free; petals generally 5, free, oblong-cup-shaped, each ± bulged at base; stamens generally 10, anthers dehiscent 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, dehiscent tip to base
Seeds many per chamber, fusiform
Species in genus: 2 species: n hemisphere
Etymology: (Greek: 1 direction, from 1-sided inflorescence)
