should pass through the widest diameter of the fruit, cutting the core in half. If the core is not in the center of the fruit, trial cuts to locate it must be made that it may be halved exactly.
The stamens, calyx-tube, and styles.—After halving the fruit longitudinally, the first organs to be studied are the stamens, the position of which furnishes reliable taxonomic data in apples and is occasionally worth noting in pears. Passing from the stamens to the calyx-tube, it will be found that the shape of this structure is of some use in separating varieties, although it is exceedingly variable in accordance with the size of the pear, and is materially altered by abnormalities in the fruit. The base of the styles in some varieties develop into fleshy tissue which alters the shape of the calyx-tube. The calyx-tube may be cone-shaped, funnel-shaped, or urn-shaped. When funnel-shaped, the broad upper part is called the limb; the narrow lower part, the cylinder. In some varieties the remnants of the styles are often more or less fleshy and form a point, called the pistil point, which projects into the calyx-tube.
The core.—The position of the core in the fruit is often a valuable means of distinguishing varieties. If close to the stem, the core is said to be sessile; if at the center of the pome, it is median; when distant from the stem, distant.
The cell containing seed, called a carpel, is morphologically a modified leaf, which, by folding together and by union of its edges forms a closed receptacle. In some varieties, the carpels are open; in others closed. If the tip of the carpel is indented, it is said to be emarginate; if long and pointed, mucronate. In shape, carpels may be round, cordate, obcordate, elliptical, oblong, elongated, ovate, or obovate. In the cores of most pomes there is a central cavity called the core cavity, sometimes spoken of as the axial sac which may be either narrow, wide, or lacking. This is a character of much importance and reliability in pears. When the carpels extend quite to the axis of the fruit, they are said to be axile and there is no core cavity; when distant from the axis, they are abaxile and a core cavity is formed. Sometimes the carpel is lined on the inner surface with a white substance, when it is said to be tufted. In some pears, there are many fine hairs in the core-cavity in which case the cavity is said to be tufted.
The limits of the core are marked by a line in most pome-fruits—usually very distinct in apples and quinces—which in most varieties of pears is indistinct. The area enclosed by this line may be large or small and may be variously shaped. When the core-line joins the calyx-tube along the sides, it is said to be clasping; when the two ends of the line meet at the base of the calyx-tube, the expression core-lines meeting is used. The core-line in pears is nearly always, if not always, clasping and very often it is a more or less thickened area of grit-cells.
Seeds.—Seeds are characteristic in all varieties of pears and might well be used more generally than is the case in classification. The number is exceedingly variable in different varieties. The usual number is two in each cell, but often there are three or more and occasionally they are missing. Seeds vary greatly in different varieties in size, shape, and color, and differences in these characters are as constant as are those of any other organ of the fruit. Number, size, shape, and color of seeds should be noted with care in every technical description of a pear. The point of the seed, also, is worth noting; it may be acute, acuminate, or obtuse. Like the carpels, the seeds are often tufted. There are several so-called seedless pears, but all of these occasionally contain some seeds. Very often seedlessness is brought about by lack of proper pollination. An occasional fruit without seeds is found in nearly all varieties, but these fruits are usually more or less abnormal in size or shape.
Flesh.—Most pears may be identified from the flesh-characters without a glance at any other part of fruit or plant. Flavor, odor, and texture of flesh are distinct in almost every variety, and appeal more strongly to the senses of taste and smell than characters measured by the eye do to the sight. Unfortunately, flavors, odors, and textures are difficult to describe.
All characters of the flesh vary greatly in accordance with conditions of growth, soil and climate having a profound influence on texture, flavor, and quality. It is important, also, in describing the flesh to have the fruit at the proper stage of maturity, and as immaturity verges into maturity and maturity into decay almost imperceptibly, each condition affecting the flesh, it is not surprising that differences of opinion may be many in judging the flesh-characters of a fruit.
In cutting a pear the color of the flesh is first noted. It may be nearly white, as in Flemish Beauty; tinged with yellow, as in Tyson; greenish-white as in Bartlett; or tinged with red, as in Joséphine de Malines. Pears with red flesh are occasionally found, but no standard varieties have flesh of this color. Sanguinole, grown more or less in Europe, has flesh of a wine-red color. Very often the texture of pear-flesh is marred by grittiness to which some varieties are much more subject than others. In most cases, however, the grit-cells are abnormal, and a discussion of their presence and cause belongs under the head of diseases in another chapter.
One determines the nature of the texture by cutting the fruit, through pressure by the fingers, and by eating. The texture may be coarse or fine; tender or tough; crisp, breaking, melting, or almost buttery; dry or juicy.
Flavor and quality.—Pears are readily divided into two classes as to flavor; they are either sweet or sour. The qualifying terms mildly and very are often used with sweet and sour. Subacid, tart, and sprightly are sometimes most expressive. Austere refers to a flavor more or less sour with some astringency. The flavor may often be put down as astringent. All varieties have a more or less distinct aroma. Rich and refreshing are words often found in the rather extensive vocabulary necessary to describe the flavor of this fruit.
Quality is that combination of texture, flavor, and aroma which makes a fruit pleasant to the palate. Quality is rated by common consent of pomologists by five grades: Poor, fair, good, very good, and best. It should be noted that good in this rating signifies a fruit of but medium quality.
The characters of pears are graphically shown on the opposite page in a descriptive form filled out for Bartlett in a description of this variety for The Pears of New York. This is, however, but a skeleton, and most of the characters must be more fully described than a form like this permits. Few pomologists in these days have the temerity to offer a description compiled in whole or in part. Descriptions are worth while only when made from living specimens before the eyes of the describer.
SPECIES OF PEARS
The foregoing pages discussing the characters of pears were preparation for a proper understanding of descriptions of pears. A discussion of the species which constitute or may constitute forms for cultivation either for their fruit or as stocks upon which to grow edible pears logically follows.
Edible pears fall into two well-marked groups: Those coming from Europe and northwestern Asia, occidental pears; and those coming from eastern and northeastern Asia, oriental pears.
OCCIDENTAL PEARS
In this group belong the thousands of varieties under common cultivation in Europe, the United States, and in temperate regions settled by Europeans. These pears are distinct from oriental pears in place of origin, and by fairly well-marked botanical characters. Thus, the leaves of these occidental pears are crenate-serrate and entire and never setose-serrate; and the calyx is persistent on the fruits. For most part, the fruits of the two divisions are quite distinct, especially in shape, but no constant line of cleavage can be found in the pears. There are several species of these occidental pears grown for their
