Pedicularis bracteosa var. flavida

YELLOWISH LOUSEWORT


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: +- 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.

Genus: PedicularisView DescriptionDichotomous Key


Common Name: LOUSEWORT
Habit: Perennial herb, +- green. Stem: decumbent to erect, generally 1--several from generally short caudex. Leaf: alternate, generally +- basal, generally < inflorescence, toothed or generally > 7-lobed, generally reduced distally on stem; petiole generally < blade. Inflorescence: raceme, spike-like; bracts (at least proximal) generally +- like distal leaves; pedicels 1--6 mm. Flower: calyx lobes (2,4)5, distal-most generally shortest (all generally < tube), lateral fused in pairs; corolla white or yellow or pink to red or purple, upper lip hood- or beak-like, curved or not, lower lip 3-lobed, narrow to fan-shaped, central lobe generally smallest; fertile stamens 4, generally glabrous, anthers generally included, sacs 2 per stamen, equal; stigma head-like, generally exserted. Fruit: generally +- ovate or lanceolate in outline, asymmetric, opening mostly on upper side. Seed: smooth or netted.
Etymology: (Latin: lice, from belief that ingestion by stock promoted lice infestation)

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.
