Group II.—Depressi—Flat. These are constantly broader than high.[47]
After a long and careful consideration and study of this subject, I have prepared the following formula for the Classification of Apples. It consists of four classes that are based upon the general figure of the fruit; with two orders, that are distinguished by a modification of the form, causing the fruit to be regular, or irregular, and angular. The characters upon which the classes are founded are exemplified by a vertical section through the length of the axis of the fruit. Those by which the Orders are distinguished are shown by a transverse section, made at right angles to the axis, or by holding the fruit with the blossom end toward the eye.[48]
Each of these Orders may contain two Sections, characterized by their flavor as sweet and sour; and each of these may again be sub-divided into three Sub-sections, that are based upon color.
Class I.—Oblate or Flat, having the axis shorter than the transverse diameter.
Order I.—Regular.
Order II.—Irregular.
Section 1.—Sweet.
Section 2.—Sour.
Sub-section 1.—Pale or blushed, more or less, but self-colored and not striped.
Sub-section 2.—Striped or Splashed.
