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.

Vaccinium parvifolium Sm.
NATIVE
Habit: Shrub, glabrous to puberulent, rhizome generally 0. Stem: erect, 1--4 m, generally not rooting; twigs strongly angled, green. Leaf: deciduous, rarely evergreen in young pls, 10--25 mm, elliptic to ovate, thin, entire to serrate or with only deciduous, sharp point at tip, abaxially (especially midvein) puberulent, veins prominent. Inflorescence: flowers 1 in axils of lowest leaves of youngest shoots; pedicel not jointed to flower, bractlets 0. Flower: calyx lobes +- 0 or < tube, rounded, deciduous; corolla < 5 mm, +- green or +- pink; anthers awned. Fruit: 6--10 mm diam, bright red. Chromosomes: 2n=24.
Ecology: Moist, shaded woodland; Elevation: 3--1400 m. Bioregional Distribution: NCo, KR, NCoRO, n&c SNH, SnFrB; Distribution Outside California: to southeastern Alaska. Flowering Time: May--Jun
Unabridged Note: Alison Colwell (pers. comm.) reports that plants from Yosemite area differ in being more lax, rooting along branches, having fruit blue-black with calyx ring, sweet taste, and possibly in seeds.

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.
