Older plants produce a mat of stems over the host and entwine and attach to the host with sucker-like organs called haustoria. Roots are non-existent or very reduced. Roots support the seedling until attached to the host. The root system is not suitable for nutrient uptake, but can absorb water. However, dodder is succulent and seldom needs water as a seedling.
Flowers are white to pink, bell-shaped, inconspicuous, in small numerous compact clusters.
Flowering occurs from early summer to early autumn. Fruits are two to four globular capsules with a slight depression on top. Dodder seeds are easily confused with alfalfa and clover seeds. However, some species have a distinguishing rough seed coat. Dodder, Cuscuta spp.
