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
Perennial herb, ± green. Stem: decumbent to erect, generally 1–several from generally short caudex. Leaf: alternate, generally ± basal, generally < inflorescence, toothed or generally > 7-lobed, generally reduced distally on stem; petiole generally < blade. Inflorescence: raceme, spike-like; bracts (at least proximal) generally ± like distal leaves; pedicels 1–6 mm. Flower: calyx lobes (2,4)5, distal-most generally shortest (all generally < tube), lateral fused in pairs; corolla white or yellow to red or purple, upper lip hood- or beak-like, curved or not, lower lip 3-lobed, narrow to fan-shaped, central lobe generally smallest; fertile stamens 4, generally glabrous, anthers generally included, sacs 2 per stamen, equal; stigma head-like, generally exserted. Fruit: generally ± ovate or lanceolate in outline, asymmetric, opening mostly on upper side. Seed: smooth or netted.Key to Pedicularis
± 500 species: cool wet northern temperate, circumboreal, South America. (Latin: lice, from belief that ingestion by stock promoted lice infestation) [Ree 2005 Int J Plant Sci 166:595–613]
Stem: mostly underground, 3–20 cm, sparsely tomentose; caudex long. Leaf: basal 5–22 cm, generally > inflorescence, ± lanceolate, segments 11–25, lanceolate to ovate, toothed to lobed, present at flower. Inflorescence: 3–12 cm; bracts hairy, proximal >> flowers. Flower: calyx 8–10 mm, ciliate; corolla 15–24 mm, ± club-like, ± yellow, generally tinged red or tipped purple, hairy, upper lip 7–10 mm, hooded, lower lip 5–7 mm, lobes ± equal, rounded; anthers 2–2.5 mm, exserted, base acuminate, filaments hairy. Fruit: 6.5–10 mm. Seed: 3.5–4.5 mm, smooth.
Dry ridgetops, conifer forest, often with red fir; 1500–3500 m. High North Coast Ranges, High Cascade Range, Sierra Nevada, Transverse Ranges, Peninsular Ranges; Nevada. May–Jul [Online Interchange]
