Intermediate Form of Plumcot
The typical plumcot differs so widely from either of its parents that it is entitled to be called a distinct species. Some varieties, however, show a peculiar segregation of the parental characteristics. The specimen here shown reveals the plum ancestry in the mottled character of its skin, while the seed, blossomend of the fruit, lopsidedness and firmness of flesh, indicate apricot parentage.
