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 10–60 cm, green, branches few to many; roots ± yellow. Leaf: alternate, sessile, 5–35 mm, entire, lanceolate to oblong. Inflorescence: spike, loose to dense, subtended by outer, leaf-like bracts; inner bract 1 per flower, ± leaf-like, entire or pinnately lobed. Flower: calyx = or slightly < corolla, sheath-like, generally cut completely to base abaxially, partially surrounding corolla tube laterally, notched ± 1 mm at tip; corolla 2-lipped, club-shaped, tubular below, expanded laterally, upper lip folded lengthwise, tip rounded, closed, opening directed downward forming a hood enclosing anthers and style; lower lip <= upper lip, obscurely 3-lobed; fertile stamens 4 and staminodes 0, or 2 with adaxial pair of staminodes (attached deeper in corolla tube), anther sacs generally 2 per stamen, ± overlapping, tufted-hairy at base, unequal in size and placement; ovary 2-chambered, glabrous, ovules many, style bent near tip, stigma barely exserted. Seed: attached at side; seed coat tight-fitting, netted.Key to Chloropyron
4 species: saline and alkaline habitats, western North America. (Greek: salt plant) [Tank et al. 2009 Syst Bot 34:182–197] Formerly included in Cordylanthus. Close to Dicranostegia, together forming the Pseudocordylanthus clade (see Tank et al. 2009); distinguished by salt-tolerant ecology, inflorescence, calyx, stamens; flowers May–Nov.

Plant 10–40 cm, gray-green, glaucous, often tinged purple and salt-encrusted, generally ± short-hairy. Leaf: 5–25 mm, lance-linear, entire. Inflorescence: spike, 20–90 mm, many-flowered; inner bract 15–30 mm. Flower: calyx 15–25 mm; corolla 15–25 mm, white to cream, puberulent, lips pale to ± brown or purple-red; fertile stamens 4, anther sacs 2 (proximal pair) or 1 (distal pair). Seed: ± reniform, deeply netted, dark brown.
