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: +- 100 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. eFlora Treatment Author: Margriet Wetherwax, except as noted Scientific Editor: Robert W. Patterson, Bruce G. Baldwin.
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. Etymology: (Greek: straight fruit) Note: Close to Cordylanthus; other species formerly placed here are Castilleja (owl's-clovers) or Triphysaria (Johnny-tuck). eFlora Treatment Author: Margriet Wetherwax, T.I.

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.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
