“ Disjunction is more frequent in dry fruits than in fleshy ones. In the latter instance it happens at an early stage of existence, and the pericarp becomes more or less leafy, losing its faculty of becoming fleshy, as in Prunus Cerasus and Amygdalus persica; nevertheless, fleshy fruits sometimes become disunited. I have seen a case similar to that mentioned by M. Alphonse de Candolle in Solanum esculentum, in which the pericarp became ruptured, and the placentas protruded. A like occurrence has also been observed in a species of Melastoma. ”
