Orobanche pinorum is a species of broomrape known by the common name conifer broomrape. 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 10–30 centimetres (3.9–11.8 in) 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 1–2 centimetres (0.39–0.79 in) long.[2]
Orobanche 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]
