Orthocarpus luteus


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: 101 genera, 2060 species: worldwide, especially northern temperate and Africa. Note: High yield losses in many crops caused by Orobanche and Phelipanche species in Africa, Mediterranean, Middle East, and eastern Europe. Taxa of Orobanche in TJM2 treated here in Aphyllon and Phelipanche.

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).

Orthocarpus luteus Nutt.
NATIVE
Habit: Plant 10--40 cm, yellow-green, often becoming +- purple-tinged, glandular- and longer-nonglandular-hairy. Stem: generally simple, slender. Leaf: 15--50 mm, +- linear, entire or upper deeply 3-lobed. Inflorescence: 5--20 cm, densely glandular-puberulent; bracts grading into distal leaves, 10--20 mm, +- green, 2 lateral lobes proximal to middle, narrowly triangular, central lobe +- lanceolate, 2--5 mm wide. Flower: calyx 5--8 mm, divided 1/3 abaxially, 3/4 adaxially, 1/4 on sides; corolla 10--15 mm, golden-yellow, exserted, puberulent (especially beak), lips +- equal, beak 2--4 mm, tip obscurely hooked, downward-projecting, cylindric, lower lip moderately pouched, teeth 3, 0.5 mm, blunt, incurved; stigma included. Fruit: 5--7 mm. Seed: 20--35, +- yellow to dark brown. Chromosomes: 2n=28.
Ecology: Moist fields, sagebrush scrub, mountain meadows; Elevation: 1300--3000 m. Bioregional Distribution: GB, adjacent edges; Distribution Outside California: to British Columbia, north-central United States, New Mexico. Flowering Time: Jul--Aug
