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.
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) eFlora Treatment Author: Linda Ann Vorobik & David J. Keil Reference: Ree 2005 Int J Pl Sci 166:595--613
NATIVE Habit: Plant +- glabrous to soft- to coarse-brown-hairy. Stem: 10--50 cm. Leaf: basal 5--20 cm, lance-oblong, segments 13--41, often crowded and distal +- overlapping, +- linear to ovate, deeply doubly lobed and dentate. Inflorescence: 4--12 cm; proximal bracts +- = to > flowers. Flower: calyx 12--24 mm, generally hairy, lobes +- equal; corolla 23--43 mm, bent downward at mid-length, deep red to red-purple or orange-yellow, generally minutely hairy, tube included at flowering, upper lip 14--26 mm, straight, club-like, hooded, lower lip 3--7 mm, lobes +- equal; anthers 2--3 mm, base acute. Fruit: 8--13 mm. Seed: 2.5--4.5 mm, surface netted. Ecology: Montane conifer forest; Elevation: (150)600--2100 m. Bioregional Distribution: CaR, SN; Distribution Outside California: southern Oregon. Flowering Time: Apr--Jun Note: Pollinated by hummingbirds; relationship to P. densiflora warrants further study. Unabridged Synonyms: Pedicularis densiflora Hook. subsp. aurantiaca E.F.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
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.
