7. Orobanche L. (broomrape)

Plants annual (perennial elsewhere), holoparasitic, lacking chlorophyll, variously glabrous to short-hairy and/or short glandular-hairy, the base sometimes somewhat thickened, but not enlarged into a tuberous structure (tuberous-based elsewhere), lacking coralloid roots or nearly so. Stems white to yellow, yellowish brown, or brown, sometimes tinged with purple. Scale-leaves relatively densely spirally alternate, appressed, lanceolate to ovate, broadly or obovate. Inflorescences spikes, racemes, or the flowers 1 per stem, each flower stalk subtended by a bract. Flowers with 2 small bractlets at the base of the calyx or lacking bractlets. Cleistogamous flowers absent. Calyces 5-lobed (2–4-lobed elsewhere), the lobes usually longer than the tube. Corollas variously colored, the tube somewhat curved or arching, the 5 lobes shorter than the tube, usually papery, brown, and persistent at fruiting. Stamens 4, usually included. Style included or slightly exserted, the stigma capitate to slightly concave, somewhat 2-lobed. Fruits ovoid, tapering abruptly to the persistent style, dehiscing longitudinally. About 150 species, nearly worldwide.
