Margriet Wetherwax, except as noted

Annual, perennial herb, shrub; often glandular; root-parasites, roots modified into absorptive structures. Stem: generally round in ×-section. Leaf: generally simple, generally alternate, reduced to ± fleshy scales in non-green plants lacking chlorophyll; stipules generally 0. Inflorescence: spike to panicle, generally bracted, or flowers 1–2 in axils. Flower: bisexual; calyx lobes 0–5; corolla generally strongly bilateral, generally 2-lipped (upper lip generally 2-lobed, lower lip generally 3-lobed), abaxial lobes outside other lobes in bud; stamens epipetalous, 4 in 2 pairs (sometimes 1 pair sterile), additional staminode 0(1), anther sacs unequal; ovary superior, chambers 1–2, placentas 2–4, parietal, style 1, stigma lobes 0 or 2. Fruit: capsule, generally ± ovoid, loculicidal, valves 2–4. Seed: many, small, angled; surface smooth or netted.
99 genera, 2060 species: worldwide, especially northern temperate and Africa. [Bennett & Matthews 2006 Amer J Bot 93:1039–1051] High yield losses in many crops caused by Orobanche species in Africa, Mediterranean, Middle East, and eastern Europe. —Scientific Editors: Robert Patterson, Bruce G.
