Cordylanthus rigidus subsp. rigidus


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: CordylanthusView DescriptionDichotomous Key

Common Name: BIRD'S-BEAK
Habit: Annual, gray- or yellow-green, often becoming red-purple, generally much-branched; roots +- yellow. Leaf: sessile, entire, thread-like to lanceolate or palmately 3--7-lobed, segments narrow. Inflorescence: short dense spike (subtended by bracts), < 2(5) cm or flowers 1, scattered or often clustered but not in spikes (each subtended by outer bract); outer bracts +- leaf-like; inner bract calyx-like (formerly confused with calyx), 0--7-lobed. Flower: calyx sheath-like, generally divided to base abaxially, partially surrounding corolla tube laterally, tip entire or shallowly notched; corolla club-shaped, tubular proximally, expanded laterally; upper corolla lip folded lengthwise, tip rounded, closed, opening directed downwards forming a hood enclosing anthers, style; lower corolla lip <= upper lip, obscurely 3-lobed, middle lobe tightly rolled under, tip distinctly folded inside-out; fertile stamens (2)4, anther sacs generally 2 per stamen, densely hairy at both ends and ciliate along line of dehiscence, unequal in size and placement; style bent near tip, stigma barely exserted. Seed: attached at side; seed coat tight-fitting, netted or irregularly striate.
Species In Genus: 13 species: western North America. Etymology: (Greek: club-shaped flower) Note: Close to Orthocarpus, distinguished by inflorescence, calyx, stamens; generally flowers Jul--Sep. Other taxa in TJM (1993) moved to Chloropyron, Dicranostegia.

Species: Cordylanthus rigidusView Description 


Habit: Plant 30--150 cm, yellow-green or tinged red, generally +- bristly, generally not glandular. Leaf: 10--40 mm, +- linear, often inrolled, lobes 0--3. Inflorescence: flowers 5--15 in +- compact, head-like clusters; outer bract generally 1 per flower, 5--20 mm, generally 3-lobed; inner bract 14--20 mm. Flower: calyx 10--20 mm, tube 1--2 mm; corolla 12--20 mm, +- yellow, lower side marked maroon in U-shape, pouch 3--10 mm wide, white. Seed: 1.5--2 mm, +- ovoid, wavy-striate, dark brown. Chromosomes: 2n=28.
Note: Highly variable, intergrading. Many geographic races, variably distinct; 5 most discrete (1 in Baja California) considered subspecies.

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.
