Shrubs or trees, multicellular hairs present or, sometimes, absent (Comarostaphylis); bark smooth, not furrowed, often flaky, sometimes shredding. Stems erect or prostrate. Leaves persistent (deciduous in Arctous), usually alternate, sometimes opposite or whorled (Ornithostaphylos), rarely opposite (Xylococcus); petiole usually present, sometimes absent (Arctostaphylos); blade plane, abaxial groove absent. Inflorescences terminal, panicles or racemes; perulae absent; bracts much shorter than sepals; bracteoles 2 or absent (Arctostaphylos, Arctous). Flowers pendulous; sepals (4-)5; petals (4-)5, connate, corolla deciduous, usually urceolate, sometimes cylindric, conic, or globose, lobes much shorter than tube; intrastaminal nectary disc present; stamens (8-)10; anthers dehiscent by slits or pores; ovary 2-10-locular; placentation axile; style straight. Fruits drupaceous (baccate in Arbutus), (pulp mealy or juicy), indehiscent; pyrenes 1-5, often connate into stonelike endocarp. Seeds 1-10, usually distinct, sometimes connate, globose (sometimes 3-sided), not winged.
