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

Inflorescence: 4--20 cm; proximal bracts +-= to > flowers. Flower: calyx 10--18 mm, generally hairy, lobes +- equal; corolla 23--43 mm, bent downward at mid-length, deep red to red-purple to orange-yellow (white), generally minutely hairy, tube exserted at flowering, upper lip 15--25 mm, straight, club-like, hooded, lower lip 8--16 mm, lobes +- equal; anthers 2--3 mm, base acute. Fruit: 8--13 mm. Seed: 2.5--4.5 mm, surface netted. Ecology: Chaparral, oak/pine woodland, mixed forest; Elevation: 30--1200 m. Bioregional Distribution: NW, n SNF, CW, SW; Distribution Outside California: southern Oregon. Flowering Time: Feb--May Note: Pollinated by bumblebees and hummingbirds.

MAP CONTROLS 1. You can change the display of the base map layer control box in the upper right-hand corner.
2. County and Jepson Region polygons can be turned off and on using the check boxes.
(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.
