It undoubtedly originated in France and in that part of the country later conquered by the Germans, though Mas, in his _Pomologie Générale_, mentioned it as probably of German origin. In the time of Louis XIII this variety was known as the Guigne Noire Commune and was cultivated quite extensively in France and northern Italy. It was esteemed both for its earliness and its fine quality and was known as Guigne Guindoulle by the peasants of central France and by the Tuscans in Italy as Corbini because of the color of its skin. Black Guigne, Black Heart, and Early Purple, which, while similar in many characters, are entirely distinct, have been badly confused by both French and German writers and it is only with the greatest difficulty that the three can be separated. While this cherry was formerly considered of worth in Continental Europe, it is scarcely recognized there now and was probably never brought to America. The following description is compiled from European fruit-books: [Illustration: BING] Tree very large, round-topped, spreading, irregular in outline, productive; branches long, large, straight, brownish, mottled with gray scarf-skin; internodes long and unequal; leaves large, oval or oblong, acuminate; margin irregularly serrate; petiole long, slender, with large glands; blooming season late; flowers small. Fruit matures the last of June to the middle of July, usually attached in pairs but sometimes in threes; medium to large in size, obtuse-cordate; color bright reddish-black changing to deep purple; suture indistinct; stem slender, inserted in a deep, broad cavity; skin thin, tender; flesh dark purple, with abundant colored juice, half-tender, somewhat stringy, sweet yet sprightly, pleasantly flavored; quality good; stone small, oval.
