Foliage of the Japanese Quince
The thick, fibrous leaves of the Japanese quince add to the beauty of the tree. The branches, however, are likely to be spiny. The quince appears to represent a somewhat more primitive type of plant than most other of our cultivated fruits. Mr. Burbank suggests that the cultivated quince of today is in about the condition of development represented by the pear of the Roman time.
