Fruit of broad-leaved trees
A broad-leaved, broad-leaf, or broadleaf tree is any tree within the diverse botanical group of angiosperms that has flat leaves and produces seeds inside of fruits. It is one of two general types of trees, the other being a conifer, a tree with needle-like or scale-like leaves and seeds borne in woody cones. [1] Broad-leaved trees are sometimes known as hardwoods. [2]
Most deciduous trees are broad-leaved [3] but some are coniferous, like larches. [4]
| Gymnosperms (seed plants not flowering) | Angiosperms (flowering seed plants) |
|---|---|
| Coniferous (females bearing ovulate cones that release unenclosed seeds at maturity) | Fruit-bearing (enclosing seeds within) |
| Usually evergreen (gradually shedding foliage, green foliage throughout year) | Usually deciduous (seasonally shedding all foliage, no foliage for part of year) |
| Known as softwoods (nonporous, wood typically lighter & softer) [5] | Known as hardwoods (wood structure porous & more complex, wood generally harder) [5] |
| Usually needle-like or scale-like leaves | Broad leaves |
| Examples: firs, spruces, pines | Examples: hickories, maples, oaks |
In botany, an evergreen is a plant which has foliage that remains green and functional throughout the year. This contrasts with deciduous plants, which lose their foliage completely during the winter or dry season.
Tilia cordata, the small-leaved lime or small-leaved linden, is a species of tree in the family Malvaceae, native to much of Europe. Other common names include little-leaf or littleleaf linden, or traditionally in South East England, pry or pry tree. Its range extends from Britain through mainland Europe to the Caucasus and western Asia. In the south of its range it is restricted to high elevations.
Betula nigra, the black birch, river birch or water birch, is a species of birch native to the Eastern United States from New Hampshire west to southern Minnesota, and south to northern Florida and west to Texas. It is one of the few heat-tolerant birches in a family of mostly cold-weather trees which do not thrive in USDA Zone 6 and up. B. nigra commonly occurs in floodplains and swamps.
Temperate rainforests are rainforests with coniferous or broadleaf forests that occur in the temperate zone and receive heavy rain.
Arbutus menziesii, or Pacific madrone, is a species of broadleaf evergreen tree in the family Ericaceae. It has waxy foliage, a contorted growth habit, and flaky bark.
Larix laricina, commonly known as the tamarack, hackmatack, eastern larch, black larch, red larch, or American larch, is a species of larch native to Canada, from eastern Yukon and Inuvik, Northwest Territories east to Newfoundland, and also south into the upper northeastern United States from Minnesota to Cranesville Swamp, West Virginia; there is also an isolated population in central Alaska.
Juglans nigra, the eastern American black walnut, is a species of deciduous tree in the walnut family, Juglandaceae, native to North America. It grows mostly in riparian zones, from southern Ontario, west to southeast South Dakota, south to Georgia, northern Florida and southwest to central Texas. Wild trees in the upper Ottawa Valley may be an isolated native population or may have derived from planted trees.
Abies grandis is a fir native to northwestern North America, occurring at altitudes of sea level to 1,700 metres (5,600 ft). It is a major constituent of the Grand Fir/Douglas Fir Ecoregion of the Cascade Range.
Fraxinus latifolia, the Oregon ash, is a member of the ash genus Fraxinus, native to western North America.
Tilia americana is a species of tree in the family Malvaceae, native to eastern North America, from southeast Manitoba east to New Brunswick, southwest to northeast Oklahoma, southeast to South Carolina, and west along the Niobrara River to Cherry County, Nebraska. It is the sole representative of its genus in the Western Hemisphere, assuming T. caroliniana is treated as a subspecies or local ecotype of T. americana. Common names include American basswood and American linden.
The western larch is a species of larch native to the mountains of western North America ; in Canada in southeastern British Columbia and southwestern Alberta, and in the United States in eastern Washington, eastern Oregon, northern Idaho, and western Montana. It is the most productive of the three species of larch native to North America.
Larix kaempferi, the Japanese larch or karamatsu in Japanese, is a species of larch native to Japan, in the mountains of Chūbu and Kantō regions in central Honshū.
Fraxinus nigra, the black ash, is a species of ash native to much of eastern Canada and the northeastern United States, from western Newfoundland west to southeastern Manitoba, and south to Illinois and northern Virginia. Formerly abundant, as of 2017 the species is threatened with near total extirpation throughout its range within the next century as a result of infestation by an invasive parasitic insect known as the emerald ash borer.
Celtis laevigata is a medium-sized tree native to North America. Common names include sugarberry, southern hackberry, or in the southern U.S. sugar hackberry or just hackberry.
Rhododendron macrophyllum, the Pacific rhododendron, California rosebay, California rhododendron, coast rhododendron or big leaf rhododendron, is a large-leaved species of Rhododendron native to the Pacific Coast of North America. It is the state flower of Washington.
Melampsora medusae is a fungal pathogen, causing a disease of woody plants. The infected trees' leaves turn yellowish-orange. The disease affects mostly conifers, e.g. the Douglas-fir, western larch, tamarack, ponderosa, and lodgepole pine trees, but also some broadleaves, e.g. trembling aspen and poplars. Coniferous hosts are affected in late spring through early August, and trembling aspens and poplars from early summer to late fall. It is one of only two foliage rusts that occur naturally in British Columbia.
Betula uber, the Virginia round-leaf birch, is a rare species of tree in the birch family. One of the most endangered species of North American trees, it is endemic to Smyth County, in the U.S. state of Virginia. It is part of the temperate broadleaf and mixed forests biome.
Sabal palmetto, also known as cabbage palm, cabbage palmetto, sabal palm, blue palmetto, Carolina palmetto, common palmetto, Garfield's tree, and swamp cabbage, is one of 15 species of palmetto palm. It is native to the far Southeast United States, the Yucatán Peninsula in Mexico, the West Indies, and the Bahamas.
Dodecadenia is a botanical genus of flowering plants in the family Lauraceae. It contains a single species, Dodecadenia grandiflora. It is present from central Asia, to Himalayas and India. It is present in tropical and subtropical montane rainforest, laurel forest, in the weed-tree forests in valleys, mixed forests of coniferous and deciduous broad-leaved trees, Tsuga forests; 2,000–2,600 metres (6,600–8,500 ft) in China in provinces of Sichuan, Xizang, Yunnan, and countries of Bhutan, India, Myanmar, and Nepal.
Phoradendron tomentosum, the leafy mistletoe, hairy mistletoe or Christmas mistletoe, is a plant parasite. It is characterized by its larger leaves and smaller berries than dwarf mistletoe. Leafy mistletoe seldom kill but they do rob their hosts of moisture and some minerals, causing stress during drought and reducing crop productions on fruit and nut trees. Leafy mistletoe has the ability to photosynthesize on its own but it relies on other plants in order to obtain its nutrients. It attaches itself to a tree and then grows haustoria, in order to get the food and water it needs.
