The last three photos shows how well these Broomrape are well camouflaged on mossy, steep, moist rock wall. Clusters of Oneflower Broomrape, each 2.5 - 3 inches tall, were growing near California Saxifrage and Hillside Woodland Star.

Oneflower Broomrape (Aphyllon purpureum) Formerly called Naked Broomrape (Orobanche uniflora) or Naked Broom Rape. It has a variety of names in different references. It is a native, small, pubescent, root-parasitic plant in the Broomrape (Orobanchaceae) family that grows 3.5–18cm (up to 7 inches) tall in moist soils. It is parasitic on members of sunflower and saxifrage families. There are no leaves on single stem that bears one long, tubular purple flower with orange filaments. Peak bloom time: April-July.

Monterey County Wildflowers:
"Naked Broomrape – Aphyllon purpureum (formerly Orobanche uniflora) grows in "moist places, parasitic on members of sunflower and saxifrage families. It is a true parasite, without photosynthetic leaves. It has 1-3 beautiful, small bluish-purple flowers, on pedicels 3–12 cm long. Most of the plant’s stem is underground. This species generally has pale purple (occasionally deep violet) to yellowish flowers.
[Note: All native California members of the Orobanche genus have been moved to the Aphyllon genus (see Jepson eFlora Revision 5, December 2017). It is now considered that A. uniflora is not found in California and that California plants previously treated as Orobanche uniflora did not belong to that species.]"
