Orobanche ludoviciana, the Louisiana broomrape[1] or prairie broom-rape, is a species of plant in the family Orobanchaceae.[2] It was first described and named by Thomas Nuttall in 1818.[3]
This species is parasitic on neighboring plants via its roots; common host species include gumweed and wormwoods, though some other Asteraceae are also used.[3] They grow from 1-3 dm often without branches.[3] Leaves are scales and numerous. The inflorescences are many-flowered spikes that occupy a half to a third of the shoot. Flowers sessile or with small up to 15mm pedicels for the lower flowers. Calyx subtended by 1 or 2 bracts, which are bilabiate. Corolla is 1.5-2.5 cm and often a violet-like color. 2n=24, 48, 72, 96. It typically grows in sandy soil. It grows throughout the central plains of North America and northwest into British Columbia and Oregon.[3] Found from June through August.[4] Listed as endangered in Wisconsin and threatened in Illinois and Indiana.
