Con*vol"vu*lus (?), n.; pl. L.Convolvuli (#), E. Convoluluses (#). [L., bindweed, fr. convolvere to roll around. So named from its twining stems.] (Bot.) A large genus of plants having monopetalous flowers, including the common bindweed (C. arwensis), and formerly the morning-glory, but this is now transferred to the genus Ipomæa.

The luster of the long convolvuluses
That coiled around the stately stems.
Tennyson.
