1. Their ground color is green, changing to dingy dull yellow.--2. The coatings of russet are very conspicious.--3. The side next the sun is often dingy, brownish, or ochreous-red.--4. They all decay very readily. GROUP 4. FRUCTUS AUREI.--_YELLOW OR GOLDEN FRUIT._ GOLDEN REINETTES. 1. On the side next the sun they are washed or striped with beautiful crimson.--2. The ground color changes by keeping, to beautiful deep yellow.--3. Over the crimson there is a light, thin trace, or complete covering of russet. CLASS IV. MALA MALARIA.--_PERFECT OR PURE APPLE SHAPED._ They are of a perfectly sweet or vinous flavor, approaching to pure acid. ORDER I. STRIOLA.--_STRIPED APPLES._ 1. They are all, and almost always, marked with broken stripes of red.--2. These are either over the whole fruit, or only indistinctly on the side exposed to the sun.--3. The stripes may all be distinct, that is, clearly and finely striped; or between these stripes on the side next the sun, the fruit is dotted, shaded, or washed with red; but on the shaded side, the stripes are well defined.--4. The cells are regular.--5. The fruit does not decay, except when gathered before maturity, or after the period when it has been properly ripened. GROUP 1. FRUCTUS DEPRESSI.--_FRUIT FLAT._ 1. They have the bulge at the same distance from the eye, as from the stalk, and are broadly flattened.--2. They are always half an inch broader than high. GROUP 2. FRUCTUS ACUMINATI.--_POINTED FRUIT._ 1. They are broader than high.--2. They diminish from the middle of the apple towards the eye, so that the superior half is conical or pyramidal, and is not at all similiar to the inferior half. GROUP 3. FRUCTUS OBLONGI.--_FRUIT OBLONG OR CYLINDRICAL._ 1. The height and breadth are almost equal.--2. They diminish gradually from the base to the apex.--3. Or from the middle of the fruit, they gradually diminish towards the base and apex equally. GROUP 4. FRUCTUS SPHÆRICI.--_FRUIT ROUND._ 1. The convexity of the fruit next the base and the apex is the same.--2. The breadth does not differ from the height, except only about a quarter of an inch.--3. When laid on their sides they present a spherical shape. ORDER II. CONTUBERNALIA.--_STORING OR HOUSEHOLD APPLES._ 1. Having the cells regular.--2. They are not striped, and are either of an uniform color, or washed with red on the side next the sun.--3. They do not decay readily.--4. They are not unctuous when handled.--5. They are never covered with bloom. GROUP 1. FRUCTUS ACUMINATI.--_FRUIT TAPERING._ Diminishing towards the eye. GROUP 2. FRUCTUS DEPRESSI.--_FRUIT FLAT._ They are constantly broader than high. * * * * * Such is the classification of Dochnahl, and although it is not all that could be desired, it is certainly the best which has yet been published, and will serve as a good foundation on which to raise a more perfect work.
