Trees of Iulixois 65 JUGLANS CINEREA Linnaeus Butternut The Butternut, called also White Walnut, is a tree of moderate size, with a trunk that divides into several stout limbs which spread horizon- tally and form a broad and symmetrical, round-topped crown. The com- pound leaves, which are 15 to 30 inches long, are made up of from 6 to 18 nearly sessile leaflets arranged in pairs (not necessarily opposite) along the stout, hairy petiole and a single terminal, long-stalked leaflet. The leaflets themselves are 3 to 4 inches long by iy2 to 2 inches wide, their blades unequally expanded on the two sides of the main nerve, the upper face yellow-green and wrinkled, and the lower face pale and covered with soft hairs. The pendulous, cylindri- cal staminate catkins grow from lat- eral buds on year-old twigs, and the pistillate flowers, which are about Ys inch long and without a stalk, are found in spikes of 6 to 8 flowers at the tip of the new growth. Both kinds of flowers are borne on the same branchlet, usually near each other. The fruit, an ellipsoid, 4- ridged, roughly corrugated, pointed nut. lies within an indehiscent, green, pulpy husk covered with glandular hairs. The stout, lustrous twigs, at first greenish but becoming reddish-or orange-brown, have dark-brown pith divided by firm diaphragms and carry small, blunt, lateral buds often superposed above the hair-fringed tops of the 3-lobed leaf scars. The terminal bud is J^ to ^ inch long and very bluntly pointed. The short, stout trunk, which is clothed by a thin, light-gray bark fissured into broad, scaly ridges, attains a diameter or 1 or 2 feet and usually divides at a height of 15 to 20 feet, but under good conditions often forms a tall, straight bole with very little taper. The tree is usually 30 to 50 feet high, but it may attain a height of 100 Fig. 20. Distribution of the Please note that these images are extracted from scanned page images that
