The Late Shipper
This is a Burbank cross between the Chinese and the Japanese plums. The Chinese parentage is shown in the short, thick, apple-like stem, clinging to the fruit, and the yellowish flesh. The influence of the Japanese parent is shown in the form of the fruit and in the stone, which inclines very strongly to the Japanese type.
