Leaves: Reduced to small, functionless scales. Flowers: Small, corollas campanulate to cylindrical and 5-lobed, most 2-6 mm long, calyx shallowly to deeply 5-lobed, stamens inserted on the corolla tube opposite the corolla lobes, styles 2, distinct, stigmas capitate, flowers borne in loose to dense cymose clusters, sessile or on short pedicels. Fruits: Capsule. Seeds 1-4. Ecology: Unknown Distribution: Arizona, New Mexico.

The parasite is usually very firmly attached when alive, but becomes easy to remove and brittle when dead. Kearney and Peebles and McDougall used for genus description only. Ethnobotany: There is no use recorded for this species, but other species in this genus have uses. Synonyms: None Editor: LCrumbacher 2012 Etymology: Cuscuta is a name of Arabic derivation meaning "dodder", while the meaning of potosina refers to San Luis Potosi, Mexico.
