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.

Common Name: WINTERGREEN
Habit: Perennial subshrub, evergreen, rhizomed. Leaf: +- basal, reniform, ovate, +- round, elliptic, or obovate, +- entire to crenate or dentate, generally petioled (if vestigial, lanceolate to deltate, +- not green, sessile). 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.
Species In Genus: +- 30 species: generally circumboreal, high mountains of Central America, Sumatra. Etymology: (Latin: little pear, +- from leaf shape) Note: Pyrola aphylla, Pyrola dentata newly recognized, added as native; Pyrola crypta newly described, added as native.

NATIVE
Leaf: generally present, 4--15 cm; blade 2.5--7 cm, ovate to obovate to elliptic, +- entire, dark green, with white mottling on veins adaxially, occasionally purple abaxially; petiole +- >= 1/2 blade. Inflorescence: < 3.5 dm including scape; flowers 5--25; flower bract 2--4 mm, generally +- 1/2 pedicel.

Ecology: Moist to dry mixed conifer forests, Pinus woodlands, volcanic areas, occasionally on decomposed granite; Elevation: 400--2400 m. Bioregional Distribution: NW, CaR, SN, SnFrB, SCoRO, SnBr, PR, SnJt, MP; Distribution Outside California: to British Columbia, New Mexico. Flowering Time: Jun--Aug Note: Occasional hybridization with other Pyrola species (pollen, seeds sometimes abortive), occasional production of clones with highly reduced leaves, appearing leafless.
