Leaves - compound (odd-feathered; leaflet, five to nine, usually seven) ; alternate, edge of leaflets sharp-toothed. Outline - of leaflets, usually long oval. Apex - taper-pointed. Base - of end leaflet, wedge-shaped, of the others more or less rounded or slightly pointed. Leaf/Stem - smooth. Leaf/Buds - egg-shape and pointed or rounded, and with their outer scales a polished-brown. Leaflet/Stems - lacking, except the smooth, very short stem of the end leaflet. Leaflets - mostly two to five inches long (the lower ones much the smallest), smooth above and below. Bark - not shaggy. Fruit - of two forms: (a) pear-shape, (b) rounded. Husks - very thin, splitting about half-way to the base. Nut - about one inch in diameter; in (b) somewhat flattened at the sides and slightly hollowed above, and with the apex a sharp point. Shell - rather thin, smooth, hard, and bluish-gray. Meat - small and sweetish or slightly bitter. Found - from Southern Maine westward and southward. 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.

Leaves - simple; alternate; edge lobed (edges of the lobes mostly entire, but notched and toothed towards the ends). Outline - narrow oval or broad oval. Base - from long wedge-shape to squared. Ends of lobes and of the teeth pointed and bristle-tipped. Leaf - three to five inches long; both sides bright green, smooth, and shining; downy in the angles of the ribs below. Lobes - seven to nine, usually seven, with the hollows between them broad and round and usually reaching about three fourths of the way or more to the middle rib. The wide type of leaf closely resembles the leaves of the scarlet oak, but it is smaller and usually the hollows reach nearer to the middle rib. Bark - smoothish (comparatively), inner bark reddish. Acorns - numerous, small, on short stems. Cup - top-shaped, shallow, and nearly smooth. Nut - rounded, one half inch long or less, sometimes broader than long, light brown. October. Found - from the valley of the Connecticut to Central New York, southward to Delaware and the District of Columbia; in Southern Wisconsin and southward; usually along streams and on low, wet land. Most common and reaching its finest growth west of the Alleghany Mountains. General Information - A handsome tree forty to sixty feet high, usually with a pointed top and with light and delicate foliage. The wood is rather coarse and not durable. It takes its name of Pin Oak from the peg-like look of the dead twigs and short branches with which the lower parts of the tree are usually set. Quercus, possible from a Celtic word meaning to inquire, because it was among the oaks that the Druids oftenest practised their rites.

Pines are native to most of the Northern Hemisphere. In North America, they range from Arctic south to Nicaragua and Hispaniola, with the highest diversity in Mexico and California. In Eurasia, they range from Portugal and Scotland east to the Russian Far East, Japan, and the Philippines, and south to northernmost Africa, the Himalaya and Southeast Asia, with one species (Sumatran Pine) just crossing the Equator in Sumatra. Pines are also extensively planted in many parts of the Southern Hemisphere.
