Annual, perennial herb, shrub; often glandular; root-parasites, roots modified into absorptive structures. Stem: generally round in ×-section.

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.
99 genera, 2060 species: worldwide, especially northern temperate and Africa.

Margriet Wetherwax & David C. Tank

1 sp.: northern Baja California, adjacent California. (Latin: 2-forked calyx) [Tank et al. 2009 Syst Bot 34:182–197] 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.
