Kazimeriz nodded. "Thank you." He looked at Professor Bunbury, then back at the class, folding his hands neatly onto the silver head of his cane. "Your Professor has given you a wonderful summary of the discovery and use of gillyweed. Gillyweed has been found in mediterranean areas as well as in many of the highland areas. It is a parasitic, sentient plant, which will burrow its roots into a host plant and steal its moisture and nutrients. In a case where gillyweed is denied the copious amounts of fresh water that it needs to survive, it will go into a period of dormancy, shriveling up and appearing as a small, prickly and hairlike plant. In this dormant state, we refer to gillyweed as Cuscuta-- also known as dodder or hairweed. Muggles have other nicknames for this plant which are considered somewhat prejudicial to members of our community. Can anyone name some of them?"
