CHALCO _Prunus simonii_ × _Prunus triflora_ =1.= Burbank _Cat._ 4. 1898. =2.= _Rural N. Y._ =57=:184, 653. 1898. =3.= _Vt. Sta. Bul._ =67=:8. 1898. =4.= _Vt. Sta. An. Rpt._ =14=:273. 1901. =5.= _Ga. Sta. Bul._ =68=:12, 35. 1905. Chalco has been extensively advertised by several nurseries but, from the reports received, it is doubtful if it will ever be grown commercially. The trees, in the East at least, are slow in coming into bearing; the fruits are small; and the flavor such that consumers will have to learn to like it although it is much better in quality than the Simon plum, one of its parents, being quite free from the bitterness of this parent. The tree is rather better than that of the Simon plum or of the Wickson, the two plums with which it must be compared. The amateur may care to plant Chalco but here its usefulness ends. Burbank in introducing this plum in 1898, stated that it was the first fruit offered after twelve years’ work in crossing _Prunus simonii_ with _Prunus triflora_ and American species. The parentage of Chalco is given as a Simon-Burbank cross. The following description is compiled: Tree vigorous, upright or somewhat vasiform, very productive; leaves large, dark green. Fruit matures shortly before Burbank; large when well grown, oblate, dark red; flesh yellowish, firm, very juicy, aromatic, sweet; good; stone small, oval, slightly flattened, semi-free.
