Cuscuta gronovii Willd. ex Schult.
Cuscutaceae (Dodder Family)
USDA Symbol: CUGR
A climbing, parasitic vine with dense clusters of small white, bell-shaped, flowers on orange-yellow stems.
Dodder seeds germinate in soil, but the roots eventually die as the plant twines around a host plant and sends out suckers that penetrate host tissues and through which it obtains all its nourishment. The species name honors Dutch botanist Jan Fredrik Gronovius, teacher of Linnaeus. Other dodders grow exclusively on such plants as flax or clover and are significant agricultural weeds. Dozens of dodders, some from Europe, are found in North America, and most are difficult to distinguish from one another. The genus Cuscuta is often placed in the morning glory family, Convolvulaceae.
