Subfamilies Monotropoideae, Pyroloideae, Vaccinioideae sometimes treated as families. Nongreen plants obtain nutrition from green plants through fungal intermediates.
Shrubs, small trees
Stem prostrate to erect; fire-resistant burl sometimes present at base; bark generally reddish, smooth or gray, rough, and shredded; hairs generally alike on twig, inflorescence axis, bract
Leaves alternate, spreading to ascending, evergreen; blade surfaces generally alike, sometimes convex, differing in color (stomata restricted to lower surface) or hairiness; margin flat to rolled
Inflorescence: raceme or panicle-like, terminal; branches raceme-like; flowers bracted; bracts leaf-like, generally flat or scale-like, generally folded, keeled; immature inflorescence present late summer through winter
Flower radial; sepals generally 5, free, persistent; corolla generally 5-lobed, urn-shaped to ± spheric, white to pink; stamens generally 10, included, filament base glabrous or hairy, anther 2-pored, awns 2, recurved; ovary superior, base surrounded by nectary disk, chambers 210, ovule 1 per chamber, style 1, stigma head-like
Fruit: drupe, berry-like, generally ± spheric; pulp generally thick, mealy; stones 210, free, separable, or strongly fused
Species in genus: ± 60 species: North America (especially CA) to C.Am, Eurasia
Etymology: (Greek: bear berries)

Observation of hairs requires 10X magnification. Distribution of many species local; hybridization occurs in areas of overlap
Horticultural information: Beautiful but mostly DFCLT due to fungus and often salinity and alkali. Avoid overhead watering in hot weather. CVS are the easier garden subjects.
