Cuscuta californica var. papillosa (Chaparral dodder) is a native California vine in the Convolvulaceae family, recognized by papillate surfaces diagnostic.

Chaparral dodder is a California native parasitic plant found in the northern Coast Ranges, Sierra Nevada foothills, Central Valley, southern Coast Ranges, and southern Coastal regions in chaparral habitats at elevations below 1,500 meters. Flowering from March to September, this plant produces small, densely papillate flowers with a distinctive spheric to spheric-depressed appearance. Growing as a threadlike, yellow-orange parasitic vine that attaches to host herbs and shrubs, it lacks chlorophyll and relies entirely on its host for nutrition. Its threadlike stems wrap completely around host plants, forming intricate, web-like connections with densely packed, small flowers. The plant produces spheric seeds, typically one to four per flower cluster.
