​ABUTILON (from the Arabic aubūtīlūn, a name given by Avicenna to this or an allied genus), in botany, a genus of plants, natural order Malvaceae (Mallows), containing about eighty species, and widely distributed in the tropics. They are free-growing shrubs with showy bell-shaped flowers, and are favourite greenhouse plants. They may be grown outside in England during the summer months, but a few degrees of frost is fatal to them. They are readily propagated from cuttings taken in the spring or at the end of the summer. A large number of horticultural varieties have been developed by hybridization, some of which have a variegated foliage.
