Common Name: BROOMRAPE FAMILY
Habit: 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.
Genera In Family: 99 genera, 2060 species: worldwide, especially northern temperate and Africa. Note: High yield losses in many crops caused by Orobanche species in Africa, Mediterranean, Middle East, and eastern Europe.

Common Name: SALTY BIRD'S-BEAK
Habit: 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. Chromosomes: n=14,15,21.
Species In Genus: 4 species: saline and alkaline habitats, western North America. Etymology: (Greek: salt pl) Note: 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.

Flower: calyx 15--20 mm; corolla 15--20 mm, +- white, +- densely tomentose, middle lobe of lower lip erect; fertile stamens 2, staminodes 2; style glabrous. Seed: 1--3 mm, +- reniform, deeply netted, dark brown. Chromosomes: 2n=28.
