Boschniakia strobilacea A. Gray

Boschniakia strobilacea A. Gray. Kopsiopsis strobilacea, the California groundcone, is a species of parasitic plant in the family Orobanchaceae. It is native to California and southern Oregon, where it grows in wooded areas and chaparral. It is a parasite of Arbutus menziesii and inland manzanitas, which it parasitizes by penetrating them with haustoria to tap nutrients. The groundcone is visible aboveground as a dark purplish or reddish to brown inflorescence up to 18 cm (7.1 in) long. Pale-margined purple flowers emerge from between the overlapping bracts.
