TOOTHED WINTERGREEN


Higher Taxonomy
Family: EricaceaeView DescriptionDichotomous Key
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.

Genus: PyrolaView DescriptionDichotomous Key


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. Seed: +- 1000.
Etymology: (Latin: little pear, +- from leaf shape) Note: Pyrola chlorantha not in CA.
Unabridged Note: In Jepson eFlora Revision 2, Pyrola aphylla, Pyrola crypta, Pyrola dentata added, as native.

Pyrola dentata Sm.
NATIVE
Leaf: generally present, 3--13 cm, glaucous, bluish; blade 2--9 cm, round, ovate, elliptic, or oblanceolate, base generally tapered to petiole, entire to serrate; petiole +- 1/4--1/2 blade. Inflorescence: 8--27 cm including scape; flowers 1--20; flower bract <=1/2 pedicel. Flower: bilateral, +- open; sepals 1.1--2.3 mm, deltate; petals 4.1--8 mm; anthers 2.6--4 mm. Chromosomes: 2n=46.
Ecology: Mixed conifer forest, mixed conifer and Quercus woodland, Pinus woodland, forested serpentine and volcanic areas, hillsides of decomposed granite or loose, coarse sand or gravel near rocky outcrops; Elevation: 55--2900 m. Bioregional Distribution: NW, CaR, SN, SnFrB, TR, PR, MP; Distribution Outside California: to southwest British Columbia, Baja California. Flowering Time: Jun--Aug Note: Occasional hybridization with other species; different morphology in northern, southern California needs study.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
