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: 99 genera, 2060 species: worldwide, especially northern temperate and Africa. Note: High yield losses in many crops caused by Orobanche species in Africa, Mediterranean, Middle East, and eastern Europe.

Genus: DicranostegiaView Description 

Species In Genus: 1 sp.: northern Baja California, adjacent California. Etymology: (Latin: 2-forked calyx) Note: Formerly included in Cordylanthus. Close to Chloropyron, together forming the Pseudocordylanthus clade (see Tank et al. 2009), distinguished by inflorescence, calyx, stamens, and ecology.

Inflorescence: elongated spike, 2--10 cm, dense, subtended by +- leaf-like outer bracts; inner bracts 15--25 mm, 3--7-lobed, lance-oblong. Flower: calyx sheath-like, +- 1/2 corolla, divided > 1/2, cut abaxially to base; corolla 18--25 mm, club-shaped, white, yellow-tipped, tubular proximally, expanded laterally, upper lip folded lengthwise, tip rounded, closed, opening directed downward forming a hood enclosing anthers and style, lower lip < upper, densely white-bearded, obscurely 3-lobed, middle lobe erect, not rolled under; fertile stamens 2, anther sacs 2 per stamen, widely separated, sterile stamens reduced to rudimentary filaments or bearing sterile, long-hairy, appendages; ovary 2-chambered, glabrous, style elongate, bent near tip, stigma barely exserted. Seed: attached at side, 30--40, 1--1.5 mm, seed coat netted, tight-fitting, wavy-crested, dark brown. Chromosomes: 2n=32.
Ecology: Coastal scrub; Elevation: < 350 m. Bioregional Distribution: s SCo (sw San Diego Co.); Distribution Outside California: northern Baja California. Flowering Time: Mar--Aug Note: Threatened by urbanization.
Synonyms: Cordylanthus orcuttianus A. Gray
