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. Baldwin.
Key to Orobanchaceae
Annual, perennial herb, not green (holoparasites), generally glandular-puberulent distally; root attachment occasionally tuber-like. Stem: simple or branched. Inflorescence: generally ± spike-like (proximal flowers often short-pedicelled or on short branches), generally dense; flowers generally > 20; bracts generally lanceolate to deltate (wider on peduncle); bractlets 0 or 2. Flower: calyx lobes 4–5; corolla glandular-puberulent, generally lacking ring of hairs at stamen bases, upper lip erect to reflexed, 2-lobed, lower lip 3-lobed, spreading, throat floor with yellow folds; anthers glabrous to hairy; stigma lobes generally 2. Fruit: 2-valved; placentas generally 2, often lobed. Seed: < 0.7 mm.Key to Orobanche
140 species: worldwide, especially Mediterranean. (Greek: vetch strangler, from parasitic habit) [Heckard 1973 Madroño 22:41–70]
Plant 4–35 cm, pale to pink-purple above ground, glandular-puberulent. Stem: 1 or clustered, slender to stout, branched proximally or throughout. Inflorescence: long or branched and ± flat- to convex-topped; pedicels 0–4 cm, distal shorter; flowers generally crowded. Flower: calyx 12–20 mm, generally pale to ± pink, lobes 5, linear-triangular, >> tube; corolla ± purple or white to pink with darker veins, ± glandular-puberulent, lips 10–14 mm, generally widely flaring; upper lip obtuse to rounded; anthers woolly; placentas 4, stigma lobes 2, triangular, margins recurved.

Plant 4–10 cm. Stem: branched or not, 1–5 cm. Inflorescence: < 5 cm, convex to ± flat-topped, few-flowered. Flower: corolla 20–30 mm, tube gradually widening to 5–8 mm, lips ± white to ± yellow to pale ± purple with lavender veins.
2n=48. Uncommon. Moderately moist meadows, stream margins, on Symphyotrichum and Erigeron; 1200–1800 m. High North Coast Ranges, High Cascade Range, n&c High Sierra Nevada, San Francisco Bay Area (s Sonoma Co., ± 60 m), Modoc Plateau; to Washington. Plants with Asteraceae hosts other than Erigeron in drier habitats are undescribed taxa, possibly of hybrid origin. May–Aug [Online Interchange]
