Higher Taxonomy
Family: OrobanchaceaeView DescriptionDichotomous Key

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.

Genus: OrthocarpusView DescriptionDichotomous Key

Habit: Annual, green. Leaf: alternate, sessile, entire to 3-lobed. Inflorescence: spike; bracts generally distinct from leaves, 1 per flower, entire to 5-lobed, tips generally colored. Flower: calyx unequally 4-lobed, deepest sinus adaxial; corolla club-shaped, upper lip folded lengthwise, tip rounded, closed, opening directed downward forming a hood enclosing anthers and style, lower lip shorter, +- 3-pouched, (0)3-toothed; stamens 4, anther sacs 2, unequal; style, stigma slender. Fruit: generally +- notched. Seed: generally 8--15, often +- curved, +- keeled, attached at side; coat netted or ridged, tight-fitting.
Species In Genus: 9 species: western North America. Etymology: (Greek: straight fruit) Note: Close to Cordylanthus; other species formerly placed here are Castilleja (owl's-clovers) or Triphysaria (Johnny-tuck).
