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. Baldwin.

Linda Ann Vorobik

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.
± 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]

Key to Pedicularis

Plant generally ± hairy. Stem: 10–30 cm. Leaf: basal 3–26 cm, > inflorescence, lance-oblong, segments 15–25, oblong to ovate, doubly toothed to lobed, present at flower. Inflorescence: 2–6 cm, generally <= leaves; proximal bracts > flowers. Flower: calyx 10–14 mm, tomentose; corolla 17–24 mm, ± club-like, pink or purple to purple-red, marked darker, glabrous, upper lip 9–11 mm, hooded, lower lip 4–7 mm, lobes pointed, ± equal, not wavy-margined; anthers 1.5–2.5 mm, generally included, base acute, filaments glabrous. Fruit: 8–13 mm. Seed: 3.5–5 mm, surface netted.
Coastal chaparral and forest; < 350 m. Central Coast, San Francisco Bay Area (Santa Cruz Mtns), Outer South Coast Ranges. Widely scattered. Plants from central Central Coast (Arroyo de la Cruz, San Luis Obispo Co.) warrant further study (smaller, leaves < inflorescence, anthers often exserted with base ± acuminate).
