The second group, varieties with reddish juice and usually with very dark fruits which are more spherical or cordate in shape than the Amarelles, comprises the Morellos of several languages or the Griottes of [Illustration: _PRUNUS CERASUS_ (MORELLO GROUP)] the French. The first of these terms has reference to the color, the word Morello coming from the Italian meaning blackish while Griotte, from the French, probably is derived through agriotte from aigre, meaning sharp, in reference to the acidity of these cherries. Weichsel is the German group name for these cherries, rather less commonly used than the other two terms. The trees of the Morello-like varieties are usually smaller, bushier and more compact than those of the Amarelles. The branches, as a rule, are more horizontal, often drooping, are less regularly arranged and are more slender. The leaves, in typical varieties, are smaller, thinner, a darker green and are pendant while those of the Amarelles are either inclined to be upright or horizontal; the leaves are also toothed less deeply and more regularly. These differences in the leaves are well shown in the color-plates of the varieties of the two groups. There are differences, also, in the inflorescence and the floral organs in the extreme types but these disappear in the varieties that connect the two forms. The typical varieties of this group are English Morello, Ostheim, Olivet, Brusseler Braune, Vladimir and Riga. Attempts to give precise distinctions between the fruits and trees of the two groups fail because the varieties constituting them hybridize freely making it impossible, with the more or less blended characters, to classify accurately. The group name indicates but little more than whether the cherries have a colored or a colorless juice--a distinction well worth while for the fruit-grower. Ehrhart called Sour Cherries with colorless juice _Prunus acida_ and those with dark colored juice _Prunus austera_. To some extent botanists have followed Ehrhart's designations. Linnaeus thought the two groups sufficiently distinct to be botanical varieties of the species and denominated the cherry with colorless juice _Prunus cerasus caproniana_ and the one with colored juice _Prunus cerasus austera_.
