Description
Cuscuta goyaziana is an obligate parasitic vine characterized by its slender, leafless, reddish-brown, thread-like stems that twine around host plants. It lacks chlorophyll and obtains nutrients by penetrating host tissues with haustoria. The herbarium specimen displays these characteristic filiform stems intertwined with the broad, dark leaves of its host.
