Castilleja exserta subsp. venusta


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: CastillejaView DescriptionDichotomous Key

Common Name: PAINTBRUSH, OWL'S-CLOVER
Habit: Annual to subshrub, green. Leaf: sessile, entire to dissected. Inflorescence: spike-like; bracts becoming shorter, wider, more lobed than leaves, mature tips generally cream to red or green. Flower: calyx unequally 4-lobed, colored like bract tips; corolla upper 2 lip lobes fused, beak-like, tip open, lower lip reduced, 3-toothed to -pouched; stamens 4, anther sacs 2, unequal; stigma entire to 2-lobed, generally exserted. Fruit: +- asymmetric. Seed: generally +- brown, attached at base; coat netted, net-like walls ladder-like or not.
Etymology: (Domingo Castillejo, Spanish botanist, 1744--1793) Note: Hybridization and polyploidy common. Biologically consistent taxa difficult to define. Castilleja chrymactis Pennell not in California, sole (1947) record a misidentified, incomplete specimen.

Common Name: PURPLE OWL'S-CLOVER
Habit: Annual 10--45 cm, glandular-puberulent, stiff-hairy. Leaf: 10--50 mm; lobes 5--9, +- thread-like. Inflorescence: 2--20 cm, 2--4 cm wide; bracts 10--25 mm, white to purple-red, lobes 5--9 (lowest pair often again 2--4-lobed), +- linear, tips wider. Flower: calyx 10--22 mm, divided 1/2 abaxially, 2/3 adaxially, 1/3 on sides, colored like bracts; corolla 12--30 mm, beak 6--7 mm, densely shaggy-hairy, tip hooked, lower lip 4--6 mm, pouches 3--8 mm wide, 3--4 mm deep; filaments puberulent; stigma +- included. Fruit: 10--15 mm. Seed: 1--2 mm; coat deeply netted, loose-fitting.
Note: Highly variable; hybridizes with Castilleja attenuata, Castilleja densiflora, Castilleja lineariloba.

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.
