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.

Triphysaria
Habit: Annual, green to yellow-brown or +- purple; generally ascending-branched. Leaf: alternate or +- basal, sessile, +- linear, distal finely divided. Inflorescence: spike and/or flowers solitary in axils; bracts generally leaf-like. Flower: calyx +- equally 4-lobed; corolla tube generally slender, upper lip folded lengthwise, tip of upper 2 corolla lobes open, opening directed forward, forming a beak, lower lip deeply 3-pouched, 3-toothed, throat abruptly generally indented forming a fold proximal to lower lip; stamens 4, anther sac 1 per stamen, generally included; stigma generally slightly enlarged, entire to slightly 2-lobed. Seed: 20--80, 0.8--1.2 mm, ovoid, attached at base, dark brown; coat netted, generally tight-fitting. Chromosomes: 2n=22.
Species In Genus: 6 species: western North America, China. Etymology: (Greek: 3 bladders, from lower lip pouches) Note: Hybrids common. Related to Castilleja, Orthocarpus; isolated reproductively.
