Castilleja mendocinensis

Higher Taxonomy
Family: OrobanchaceaeView DescriptionDichotomous Key
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: CastillejaView DescriptionDichotomous Key

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.
