JUGLANS NIGRA, Linn. Black Walnut.--Leaflets eleven to seventeen, rarely more; ovate-lanceolate, smooth above, moderately pubescent beneath, pointed, somewhat heart-shaped at the base; leaf-stalks slightly downy, usually of a pale purplish color early in the season, especially on young trees; fruit large, mostly globose (Fig. 81); husk thin, roughly dotted; shell thick, hard, deeply and unevenly corrugated with rough, sharp ridges and points (Fig. 82); kernel large, sweet, but usually with a strong, rather rank taste, but less oily than the butternut. Trees grow to an immense size, with deeply furrowed bark; wood dark colored, valuable for cabinet work, inside finishing, gun stocks, etc. Common in deep, rich soils, from western Massachusetts west to southern Minnesota, and southward to Florida. Most abundant west of the Alleghany mountains, and especially in the rich valleys of the Western States distant from railroads and water communication; elsewhere the trees have long since been cut for their timber. I have only one synonym to record, and this is scarcely worthy of notice, viz.: _Wallia nigra_. (Alefeld in "Bonplandia," 1861.) [Illustration: FIG. 82. JUGLANS NIGRA, HUSK REMOVED.] =Varieties of the Black Walnut.=--As with the butternut, there are no varieties of the black walnut in cultivation; at least, none propagated by means which will insure the perpetuation of their varietal characteristics. It is true that there are plenty of wild varieties to be found, these varying widely in size and form, and somewhat in thickness of their shell, as well as the ease with which the kernels may be extracted, but none of these have been perpetuated by artificial means. Among the earliest varieties recognized by botanists, one was called Oblong Black Walnut, _Juglans nigra oblonga_, by Miller, 1754, and perhaps in earlier editions of the "Gardener's Dictionary." He says this is from Virginia, and only a variety of the common black walnut. Marshall, in 1785, describes this "black oblong fruited walnut," and adds: "There are, perhaps, some other varieties." These oblong, or, more correctly speaking, oval nuts, often sharp-pointed at both ends, are rather plentiful at this time. There are rarely any considerable number of bushels reaching market from Virginia and adjacent States, among which these oval or oblong nuts cannot be found. I have a number before me measuring from one inch to one and a quarter in diameter, and from one and a half to nearly two inches in length. Other varieties found, perhaps, in the same lot, are broader than long, or one and seven-eighths inches broad, by one and one-half in vertical diameter. These measurements are of the cleaned shell, after the husks have been removed.
