Higher Taxonomy
Common Name: HEATH FAMILY Habit: Perennial herb, 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 (2--5)8--10, free, filaments rarely appendaged, anthers dehiscing by pores or slits, awns 0 or 2(4), seemingly abaxial, reduced or elongate, generally curved; 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. Genera In Family: +- 100 genera, 3000 species: generally worldwide except deserts; some cultivated, especially Arbutus, Arctostaphylos, Rhododendron, Vaccinium. Note: Monophyletic only if Empetraceae included, as treated here. Ledum included in Rhododendron. Non-green plants obtain nutrition from green plants through fungal intermediates. eFlora Treatment Author: Gary D. Wallace, except as noted Scientific Editor: Gary D. Wallace, Thomas J.

Inflorescence: raceme, +- erect, not 1-sided, elongate; scape smooth, glabrous, bracts generally 1--several, deltate or lanceolate; flower bract 1 per flower, < to >> pedicel. Flower: radial, +- closed or subradial or bilateral, +- open, parts in 5s, free; petals without tubercles, upper 2 generally forming hood over upturned stamens; stamens 10, filaments generally widened at base, smooth, glabrous, anther generally with tube-like constrictions subtending pores; nectary 0; ovary superior, style +- included and straight or generally exserted and downcurved, stigma peltate, with 5 spreading lobes above a prominent, reflexed collar or generally not peltate, generally with 5 +- erect lobes projecting beyond a delicate, reflexed collar. Fruit: capsule, pendent; valves opening base to tip, margins fibrous. Seed: +- 1000. Species In Genus: +- 30 species: generally circumboreal, high mountains of Central America, Sumatra.
