![]() ![]() Unlike the leaves of the dandelion, the leaves of the hops plant are palmately lobed. The common hops plant, whose flowers are used to brew beer, also has lobed leaves. The dandelion is also unique in that the whole plant-including leaves, stems, and flowers-is edible it is used in Chinese, Greek, and Indian cuisine. These leaves can grow over 10 inches long. Though best known for its bright yellow flowers, the plant also has distinct pinnately lobed leaves whose projections vary in size and texture. One of the most famous plants with lobed leaves is the dandelion, which grows throughout Europe and North America. The number of projections on a single leaf varies from species to species. Other lobes are palmate, which means that they radiate from a single point (and resemble a set of fingers and the palm of a hand). Some lobes are pinnate, which means that they are arranged along a central stalk. Some lobe ends are rounded, such as those of the white oak, while others are sharp or pointed, such as those of the northern red oak or the sweetgum. Lobed leaves are those that have distinct projections from the midrib with individual inside veins. The magnolia is named after Pierre Magnol, a French scientist who invented a classification system for plant families based on their physical characteristics. Some parts of the magnolia-including the flower buds-are used in Asian cuisine and in traditional Chinese medicine. The magnolia is the official state flower of Louisiana and Mississippi. Magnolia leaves have a waxy sheen on one side and a matte texture on the other. ![]() In 1915, when Japan famously donated cherry trees to Washington, D.C., the United States sent 40 dogwood trees to Japan.Īnother famous tree with unlobed leaves is the magnolia, which grows in North America, Central America, and Southeast Asia. The tree is famous for its pink and white bracts (a type of modified leaf) and is a popular ornamental variety. One of the most well-known trees with unlobed leaves is the flowering dogwood, which grows throughout eastern North America and in parts of northern Mexico. These leaves are said to have "entire" margins. Still others have simple leaves whose margins are indeed quite smooth, including the leaves of the sassafras and eastern redbud. Others have a slightly "wavy" or sinuous leaf margin, such as the leaves of the persimmon. ![]() Some unlobed leaves have small serrations called teeth, including the leaves of the sugarbud and the American elm. This does not mean, however, that the margins have to be completely smooth. Unlobed leaves are those that lack significant projections. In the forest crowns are upright and oval with trees reaching up to 100 feet tall and several feet in diameter.The edge of a tree leaf is known as its margin. On older trees smooth patches are not uncommon.įorm: A very large tree when open grown, white oaks have rugged, irregular crowns that are wide spreading, with a stocky bole. Twig: Red-brown to somewhat gray, even a bit purple at times, hairless and often shiny multiple terminal buds are red-brown, small, rounded (globose) and hairless.īark: Whitish or ashy gray, varying from scaly on smaller stems to irregularly platy or blocky on large stems. Leaf: Alternate, simple, oblong to ovate in shape, 4 to 7 inches long 7 to 10 rounded, finger-like lobes, sinus depth varies from deep to shallow, apex is rounded and the base is wedge-shaped, green to blue-green above and whitish below.įlower: Species is monoecious male flowers are yellow-green, borne in naked, slender catkins, 2 to 4 inches long female flowers are reddish green and appear as very small single spikes appearing with the leaves in mid-spring.įruit: Ovoid to oblong acorn, cap is warty and bowl-shaped, covers 1/4 of the fruit cap always detaches at maturity matures in one growing season in the early fall. ![]()
