It is native to the forests of western North America,[1] where it is a parasite growing attached to the roots of other plants, usually Holodiscus species. This plant has an erect stem with a wide, thickened base and slender top growing {{convert|10|-|30|cm}} tall. As a parasite taking its nutrients from a host plant, it lacks leaves and chlorophyll and is brownish or yellowish in color. The inflorescence is a dense, spreading array of purple-tinged yellowish flowers {{convert|1|-|2|cm}} long.[2] ReproductionO. pinorum is predominantly autogamous. It produces about 700 seeds per capsule and over 70,000 seeds per plant. There are some evidence of xenogamy, but potential pollinators were rarely observed.[3]References1. ^{{cite web|url=http://plants.usda.gov/java/profile?symbol=ORPI2|title=Orobanche pinorum Geyer ex Hook.|publisher=Plants Profile|work=USDA|accessdate=December 5, 2009}} 2. ^{{cite web|url=http://ucjeps.berkeley.edu/cgi-bin/get_JM_treatment.pl?5502,5506,5520|author=Lawrence R.
