About

Cuscuta sandwichiana (Kauna'oa kahakai) is a parasitic vine and the only member of the genus Cuscuta (commonly called "dodder") that is endemic to the Hawaiian Islands. It parasitizes a wide variety of indigenous, endemic and introduced plants on all of the main Hawaiian islands. It grows in coastal areas with sandy soils from sea level elevation to 975 feet. The indigenous kaunaʻoa pehu (literally "swollen kaunaʻoa") Cassytha filiformis is a similar-looking species with the same parasitic nature. It is an unrelated plant in the laurel family Lauraceae which can be distinguished by its larger, coarser yellowish-green stems.
