The tree resembles the plum in growth but the fruit, in looks and flavor, is like that of the Sand Cherry. Fruit rather long with a prickle at the apex; about one and three-eighths inches in diameter; skin black with a bluish bloom, thin, free from acerbity; flesh yellowish-green, sprightly; pit clinging. =China Bigarreau.= _P. avium._ =1.= Prince _Pom. Man._ =2=:126. 1832. _China Heart._ =2.= Prince _Treat. Hort._ 30. 1828. =3.= _Lond. Hort. Soc. Cat._ 48. 1831. This variety was raised from the seed of an Ox Heart by William Prince, Flushing, New York, and at first was called China Heart. W. R. Prince in his _Pomological Manual_ of 1832, calls it China Bigarreau as it is more of the Bigarreau than of the Heart type of cherries. Tree vigorous, large; fruit medium in size, roundish or oval-cordate, with a distinct suture; stem long, slender, set in a shallow cavity; skin when fully ripe, glossy red mottled with lighter red; flesh firm, somewhat melting, with a sweet, rich, peculiar flavor; ripens just after Black Tartarian and forms a link between it and the later varieties; very productive. =Choque.= _P. avium._ =1.= Thomas _Guide Prat._ 15, 191. 1876. =2.= Mas _Pom.
