petite cuscute

Clover dodder (Cuscuta epithymum) is a parasitic flowering plant in the family Convolvulaceae, a leafless, twining vine that obtains all its water and nutrients from host plants via haustoria — specialized penetrating organs that connect to host vascular tissue. The species is almost entirely dependent on its hosts throughout its life, with only brief photosynthetic activity during germination before establishing parasitic connections. C. epithymum parasitizes a wide range of host species including clover (Trifolium), gorse (Ulex), heathers (Erica, Calluna), thyme (Thymus), and other plants in open heathland, grassland, and scrub habitats. The stems are thread-like, yellowish-pink or reddish, and support clusters of small white to pale pink flowers. Originally widespread across Europe, Asia, North Africa, and the Americas, the species has declined significantly in many parts of its range due to agricultural intensification, herbicide application, grassland conversion, and loss of semi-natural heathlands. It is currently listed as Endangered on the IUCN Red List, reflecting population decline across its European core range. Conservation of C. epithymum requires the maintenance of unimproved, low-nutrient grasslands and heathlands that support its diverse host plant communities. The species is recorded from Africa, Europe, North America, Oceania, and South America, though populations in some regions represent introductions associated with contaminated legume seed lots.
