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.

Perennial herb 15–60 cm, few-branched, green becoming ± purple, ± glabrous to bristly-puberulent, generally nonglandular. Leaf: linear to lanceolate; lobes 0–5, tips ± rounded. Inflorescence: 5–30 cm; bracts 17–25 mm, lobes 0–5. Flower: calyx divided ± 1/3–1/2 abaxially and adaxially, ± 1/4–1/3 on sides, long-nonglandular- and short-glandular-hairy, lobes acute to obtuse, generally not curved upward; corolla beak ± 1–1.5 × tube, adaxially generally shaggy-hairy, margins ± red or ± yellow, lower lip 2–3 mm, green to dark purple; stigma slightly notched. Fruit: 10–15 mm. Seed: 1.5–2 mm; coat deeply netted, tight-fitting, most walls ladder-like. Many forms, some geographically isolated; hybridizes with other species. [Online Interchange]
Plant ± bristly, occasionally some hairs branched. Leaf: 30–80 mm, ± lanceolate; lobes 0–5. Inflorescence: 30–50 mm wide, generally bright red to orange-red (yellow). Flower: calyx 20–35 mm; corolla 25–40 mm.
2n=48,72,96. Chaparral, coastal scrub; < 1800 m. c North Coast (Mendocino Co.), Outer North Coast Ranges, Inner North Coast Ranges, n Cascade Range Foothills, Sierra Nevada Foothills, Central Western California, Southwestern California; Baja California. Coastal plants tend to have ± fleshy leaves, inflated calyx. Dune plants of southern Central Coast, northern South Coast with some branched hairs may represent past hybridization with diploid Castilleja mollis of northern Channel Islands.
