Cuscuta suksdorfii (Mountain dodder) is a native California vine in the Convolvulaceae family, recognized by high elevation, long-acuminate parts, and reduced scales diagnostic.

Mountain dodder is a California native perennial found in the Klamath Ranges, northern Sierra Nevada Mountains, and San Bernardo Mountains on herbs in the Asteraceae family at elevations of 1,500 to 2,600 meters. Flowering from July to September, this parasitic plant produces small membranous flowers in umbel-like clusters with 2 to 7 blooms. Growing as a thin, twining parasitic vine, it attaches to host plants without roots or typical stems. Its flowers are distinctive, with a calyx larger than the corolla tube, bell-shaped structures with ovate lobes and triangular-ovate petals. The small translucent fruits contain 2 to 4 seeds, each approximately one millimeter wide.
