Orobanche californica subsp. jepsonii

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: OrobancheView DescriptionDichotomous Key

Common Name: BROOMRAPE
Habit: Annual, perennial herb, not green (holoparasites), generally glandular-puberulent distally; root attachment occasionally tuber-like. Stem: simple or branched. Inflorescence: generally +- spike-like (proximal flowers often short-pedicelled or on short branches), generally dense; flowers generally > 20; bracts generally lanceolate to deltate (wider on peduncle); bractlets 0 or 2. Flower: calyx lobes 4--5; corolla glandular-puberulent, generally lacking ring of hairs at stamen bases, upper lip erect to reflexed, 2-lobed, lower lip 3-lobed, spreading, throat floor with yellow folds; anthers glabrous to hairy; stigma lobes generally 2. Fruit: 2-valved; placentas generally 2, often lobed. Seed: < 0.7 mm.
Species In Genus: 140 species: worldwide, especially Mediterranean. Etymology: (Greek: vetch strangler, from parasitic habit)

Species: Orobanche californicaView Description 

Habit: Plant 4--35 cm, pale to pink-purple above ground, glandular-puberulent. Stem: 1 or clustered, slender to stout, branched proximally or throughout. Inflorescence: long or branched and +- flat- to convex-topped; pedicels 0--4 cm, distal shorter; flowers generally crowded. Flower: calyx 12--20 mm, generally pale to +- pink, lobes 5, linear-triangular, >> tube; corolla +- purple or white to pink with darker veins, +- glandular-puberulent, lips 10--14 mm, generally widely flaring; upper lip obtuse to rounded; anthers woolly; placentas 4, stigma lobes 2, triangular, margins recurved.


Orobanche californica subsp. jepsonii (Munz) Heckard
NATIVE
Habit: Plant 10--35 cm. Stem: generally branched, generally > 6 cm. Inflorescence: 5--20 cm. Flower: corolla 25--40 mm, +- white or +- pink to pale yellow-brown, tube gradually widened to 5--8 mm, veins generally +- purple. Chromosomes: 2n=48.
Ecology: Uncommon. Generally dry flats, slopes, generally on perennial herb and shrub Asteraceae; Elevation: < 2200 m. Bioregional Distribution: KR, NCoR, CaR, SNF, GV, SnFrB, SCoR. Flowering Time: Jul--Sep Note: Variation suggests an unnatural group; may include hybrids of other Orobanche californica subspecies.
