Higher Taxonomy
Family: EricaceaeView DescriptionDichotomous Key

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: PhyllodoceView DescriptionDichotomous Key

Habit: Shrub, generally matted, glabrous to glandular, generally rhizomed. Stem: decumbent, rooting, rough from persistent, decurrent leaf bases. Leaf: alternate, crowded, generally < 5 mm wide, needle-like, evergreen, leathery, abaxially channeled; margin strongly rolled under, abaxial surface < 1/3 visible. Inflorescence: raceme, bracts leaf-like; pedicel jointed to flower, bractlets 2. Flower: sepals 5, fused at base; corolla [urn- or ] cup-shaped, petals 5, +- 4/5 fused; stamens generally 10, anthers elongate, dehiscing by short separate slits, unawned; ovary superior, chambers 5, placentas axile. Fruit: capsule, septicidal, dehiscing tip to base. Seed: many per chamber, narrowly winged.
Species In Genus: 4--7 species: circumboreal. Etymology: (Greek: sea nymph; possibly leaf similar, from resemblance to Erica)
