The seeds of the pinyon pine, known as "pine nuts" or "piñóns", are an important food for American Indians living in the mountains of the North American Southwest. All species of pine produce edible seeds, but in North America only pinyon produces seeds large enough to be a major source of food.
Broadly, but not commonly, distributed. The wood is used for tool handles and furniture. The nuts are the largest among the hickories, providing food for wildlife. Uses: timber; palatable food, sap resins, veneers. [55] ME, the eastern Midwest, the Mid-Atlantic and the Southeast
Young tree in natural habitat American chestnut male (pollen) catkins. Castanea dentata is a rapidly-growing, large, deciduous hardwood eudicot tree. [20] A singular specimen manifest in Maine has attained a height of 115 feet (35 m) [21] Pre-blight sources give a maximum height of 100 feet (30 m) and a maximum circumference of 13 feet (4.0 m).

Ohio buckeye (Aesculus glabra) is usually a small to medium-size tree (20-40 feet tall) with compound leaves that have five oval-shaped leaflets. Closely related is the common horsechestnut ( A ...
Female flowers give way to distinctive clusters of winged seeds that somewhat resemble the hops-like seeds of ironwood. [ 6 ] The fruit is a small nut about 3–6 millimetres ( 1 ⁄ 8 – 1 ⁄ 4 in) long, held in a leafy bract ; the bract may be either trilobed or simple oval, and is slightly asymmetrical.
The fruit is a small 7–8-millimeter (9 ⁄ 32 – 5 ⁄ 16-inch) long nut, partially surrounded by a three- to seven-pointed leafy involucre 2–3 centimeters (3 ⁄ 4 – 1 + 1 ⁄ 4 in) long; it matures in autumn. The seeds often do not germinate till the spring of the second year after maturating. Bark: On old trees near the base, furrowed.
A specimen in the Arnold Arboretum leafing out in spring. The American basswood is a medium-sized to large deciduous tree reaching a height of 18 to 37 m (60 to 120 ft) exceptionally 39 m (128 ft) with a trunk diameter of 1–1.5 m (3–5 ft) at maturity.
The fruit is a dry egg-shaped capsule 3–4 centimetres (1 + 1 ⁄ 8 – 1 + 5 ⁄ 8 in) long, containing numerous tiny seeds. The seeds are winged and disperse by wind and water. Pollarded trees do not produce flowers, as these form only on mature wood. Paulownia tomentosa requires full sun for proper growth.
