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 to subshrub, green. Leaf: sessile, entire to dissected. Inflorescence: spike-like; bracts becoming shorter, wider, more lobed than leaves, mature tips generally cream to red or green. Flower: calyx unequally 4-lobed, colored like bract tips; corolla upper 2 lip lobes fused, beak-like, tip open, lower lip reduced, 3-toothed to -pouched; stamens 4, anther sacs 2, unequal; stigma entire to 2-lobed, generally exserted. Fruit: ± asymmetric. Seed: generally ± brown, attached at base; coat netted, net-like walls ladder-like or not.Key to Castilleja
± 200 species: especially western North America. (Domingo Castillejo, Spanish botanist, 1744–1793) [Tank & Olmstead 2008 Amer J Bot 95:608–625] Hybridization and polyploidy common. Biologically consistent taxa difficult to define. Castilleja chrymactis Pennell not in California, sole (1947) record a misidentified, incomplete specimen.

Annual 10–50 cm, nonglandular, spreading-hairy. Leaf: 20–80 mm, ± linear; lobes 0–3. Inflorescence: 3–30 cm, 1–2 cm wide; bracts 15–35 mm, lobes 3, ± lanceolate, tips white or pale yellow. Flower: calyx 10–20 mm, divided ± 1/2 abaxially, 3/4 adaxially, 1/3 on sides; corolla 10–25 mm, linear, beak 4–5 mm, straight, puberulent, lower lip 3–4 mm, pouches ± 2 mm wide, 1–1.5 mm deep, ± white, purple-dotted; filaments glabrous; stigma included. Fruit: 7–11 mm. Seed: < 1 mm; coat shallowly netted, loose-fitting.
