Parasitic herb 10 - 50 cm tall Stem: slender, with many long and ascending branches, pale brown, often with fine brownish purple lines. Leaves: alternate, 2 - 4 mm long, less than 3 mm wide, scale-like, lance-shaped, scattered along stem. Flowers: solitary, axillary, of two types. Lower flowers are female, 5 mm long, with sepals fused into a five-ribbed cup-shape and tubular petals that do not open. Upper flowers bisexual but functionally male, white with purplish brown stripes, to 1 cm long, tubular, four-lobed. Fruit: 5 mm long, slanting, opening at the top.
Similar species: Orobanche uniflora and Orobanche fasciculata are easy to distinguish by having only one to ten flowers per plant. Conopholis americana differs because it resembles an upright pine cone and has thick, unbranched stems with many large (more than 3 mm wide) triangle-shaped scales.
