Chaenomeles speciosa (Sweet) Nakai , Jap. Jour. Bot. 4: 331 (1929) ( Cydonia japonica auct., non (Thunb.) Pers.) and C. japonica (Thunb.) Spach, Hist. Vég. (Phan.) 2: 159 (1834), are widely cultivated for ornament, and may occur as escapes, though it is doubtful if they are naturalized. Chaenomeles is like Cydonia but has leaves serrate, sepals deciduous, stamens 40-60 and styles connate at the base.
