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, gray- or yellow-green, often becoming red-purple, generally much-branched; roots ± yellow. Leaf: sessile, entire, thread-like to lanceolate or palmately 3–7-lobed, segments narrow. Inflorescence: short dense spike (subtended by bracts), < 2(5) cm or flowers 1 (each subtended by outer bract); outer bracts ± leaf-like; inner bract calyx-like (formerly confused with calyx), 0–7-lobed. Flower: calyx sheath-like, generally divided to base abaxially, partially surrounding corolla tube laterally, tip entire or shallowly notched; corolla club-shaped, tubular proximally, expanded laterally; upper corolla lip folded lengthwise, tip rounded, closed, opening directed downwards forming a hood enclosing anthers, style; lower corolla lip <= upper lip, obscurely 3-lobed, middle lobe tightly rolled under, tip distinctly folded inside-out; fertile stamens (2)4, anther sacs generally 2 per stamen, densely hairy at both ends and ciliate along line of dehiscence, unequal in size and placement; style bent near tip, stigma barely exserted. Seed: attached at side; seed coat tight-fitting, netted or irregularly striate.Key to Cordylanthus
13 species: western North America. (Greek: club-shaped flower) [Tank et al. 2009 Syst Bot 34:182–197] Close to Orthocarpus, distinguished by inflorescence, calyx, stamens; generally flowers Jul–Sep. Other taxa in TJM (1993) moved to Chloropyron, Dicranostegia.

Plant 20–120 cm, (gray- or yellow-)green or tinged maroon, ± glabrous to sparsely long-hairy or glandular-sticky. Stem: ± wiry. Leaf: 10–60 mm, ± linear. Inflorescence: flowers 1 or 2–7 in loose clusters; outer bracts 1–4, 5–20 mm, linear, entire or 3-lobed, tips generally ± wider (< 1.5 mm) and thickened, longest hairs < 2 mm; inner bract 10–20 mm. Flower: calyx 10–20 mm, tip notched; corolla 10–20 mm, 4–8 mm wide, ± white, ± yellow-tipped, heavily blotched maroon. Seed: 6–16, 1.5–2.5 mm, ± ovoid or angled, finely wavy-striate, dark brown.
2n=28. Highly variable. Close to Cordylanthus pilosus. [Online Interchange]
Stem: generally puberulent (especially > 1600 m) to glandular-sticky (especially < 900 m). Leaf: linear, entire. Inflorescence: clusters loosely 1–3-flowered; outer bracts entire; inner bract hairs < 1 mm. Flower: corolla 10–20 mm.
Open conifer forests, foothill woodland; 300–2600 m. c Klamath Ranges, Sierra Nevada. Plants from central Klamath Ranges (Scott Mountains) that key here may be derived from Cordylanthus tenuis subsp. viscidus. Jul–Sep [Online Interchange]
