Habit | Plants erect to decumbent, 10–35 cm, much branched and often matted. | Herbs, shrubs, or trees perennial, deciduous or evergreen, photosynthetic or non-photosynthetic. |
Stems | younger branches glandular-pubescent; older branches glabrous. |
erect to decumbent or prostrate, glabrous or hairy. |
Leaves | overlapping, generally curving upward, becoming straight with maturity, 4–12 × 1–2 mm; margins revolute, glandular-serrulate; surfaces abaxially grooved and glandular, adaxially glabrous to glandular. |

Nearly worldwide. ~120 genera; 26 genera treated in Flora. Some authorities treat the subfamilies of Ericaceae as distinct families. Within Oregon, these would include Monotropaceae, Pyrolaceae, and Vacciniaceae. Conservatively, we have chosen not to recognize these families. Non-photosynthetic ericaceous species are often referred to as saprophytes, plants that use decaying or non-living organic matter for nourishment. In reality, these species are true parasites, obtaining all of their nutrition from mycorrhizal fungi, which in turn parasitize photosynthetic plants, usually conifers. They are more appropriately referred to as epiparasites or mycotrophs. |
