Leaves - compound (odd-feathered; leaflets, eleven to twenty-five); alternate; edge entire. Outline - oval or egg-shape. Apex, rounded. Base - rounded. Stem - of leaf, smooth, and covering the leaf-bud of the next year. Leaflets - very smooth, thin, often slightly tipped with the end of the mid-rib. Bark - of trunk, dark, rough, and very deeply ridged. The smaller branches and young trunks are armed with strong, triangular prickles, but these disappear when the parts are three to four inches thick. Flowers - showy and abundant; in long, loose clusters drooping from the sides of the branchlets; white; and very fragrant. May, June. Fruit - a smooth and rather blunt pod, two to three inches long, one and a half inches wide, four- to six-seeded. Seeds, dark brown. September. Found - Native in the Alleghany Mountains from Pennsylvania (Monroe County - Porter) to Georgia; but now very generally naturalized throughout the United States east of the Rocky Mountains. General Information - A tree usually forty to fifty feet high, sometimes ninety feet, and of rapid growth. Its wood is exceedingly hard and strong, and remarkable durable when in contact with the ground. It is used largely for posts, in ship-building, and in turnery, and it is preferred to all other native wood for tree nails. It is one of the most valuable trees of this or of any country. But is cultivation as a timber tree, which at one time was very general, has nearly ceased in the United State on account of the constant damage done by the grub of the Painted Clytus (Clytus pictus). This troublesome borer not only injures the new growth, but also pierces and detaches large branches, leaving the tree ragged and stunted.

Salix from two Celtic words meaning "near" and "water."

Leaves - compound (odd-feathered, leaflets, seven to nine); alternate; edge slightly and rather roundly toothed. Outline - of leaflets, mostly long oval, the lower pairs becoming smaller and more egg-shaped. Apex - long-pointed. Base - of the end leaflet, wedge-shape; of the others, more or less blunted. Leaf/Stem - rough throughout. Buds - large and round and covered with downy, yellowish-brown scales, or, in winter, with hard and grayish-white scales. Leaflet/Stem - lacking (or scarcely noticeable), except the short, roughish stem of the end leaflet. Leaflets - two to seven inches long, rough beneath, especially on the ribs; fragrant when crushed. Bark - rough, becoming cracked across, but not scaly. Fruit - rounded, slightly egg-shaped or oval, one and one half to two inches or more in length. The husk is about one fourth of an inch thick and splits nearly to the base when ripe. Nut - slightly six-angled, light brown, with a very thick and hard shell. Kernel - is sweet, but small. October. Found - common in dry woods, especially southward and westward. It grows in Southern Canada and I all the Atlantic States. General Information - All the Hickories are picturesque trees. Their tendency, even when standing alone, is to grow high, and with heads that, instead of being round, are cylinder-shaped to the very top, with only enough breaks and irregularities to add to the effect. This tendency is more marked in the Hickories than in any other of the leaf-shedding trees of North America. They are worthy of the name sometimes given them of 'the artist's tree." Hicoria, from a Greek word meaning round, in allusion to the shape of the nut.
