Twi'ner, a plant which climbs by coiling its body in an ascending spiral about a support, as the morning-glory or the hop-vine. In their younger parts twiners are sensitive to contact, so that when they touch a support they curve sharply about it. The twining habit, like the climbing habit in general, is most extensively developed in the tropics. See Climbing-Plants.
