Natural range of Fraxinus anomala |
Fraxinus anomala is a species of ash tree known by the common name single-leaf ash. It is native to the southwestern United States and northern Mexico, where it grows in a number of habitats including desert scrub and chaparral. It is unusual in the genus in that some (though not all) specimens have simple leaves instead of the pinnate leaves more characteristic of the group.
Fraxinus anomala is a deciduous shrub or small tree approaching maximum heights of five to six meters. The leaf may be simple or it may be compound, composed of up to five leaflets which look like individual leaves. Each leaflet is oval-shaped to round and may have teeth along the edges. The nondescript brownish flowers lack petals. The fruit is a flat samara up to two centimeters long and one wide, green when young and tan to brown when mature. The samaras hang in bunches.
In Arizona, singleleaf ash is found along the Arizona transition zone of the Mogollon Rim. In northern Arizona's Grand Canyon, the range extends down the main canyons from southern and southeastern Utah, its major range area, where the Canyon Lands also show the range entering upper reaches of river basins flowing from western Colorado – Colorado and Dolores Rivers; also the shorter Yellowjacket and McElmo Rivers in Colorado's extreme southwest. [1] In the Mojave Desert of California it is found in the sky island chaparral and woodland habitats. Minor locales also occur in southern Nevada and southern Wyoming. [1] [2]
Fraxinus, commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous trees, although some subtropical species are evergreen trees. The genus is widespread throughout much of Europe, Asia, and North America.
Fraxinus quadrangulata, the blue ash, is a species of ash native primarily to the Midwestern United States from Oklahoma to Michigan, as well as the Bluegrass region of Kentucky and the Nashville Basin region of Tennessee. Isolated populations exist in Alabama, Southern Ontario, and small sections of the Appalachian Mountains. It is typically found over calcareous substrates such as limestone, growing on limestone slopes and in moist valley soils, at elevations of 120–600 m.
Fraxinus americana, the white ash or American ash, is a fast-growing species of ash tree native to eastern and central North America.
Robinia neomexicana, the New Mexican, New Mexico, Southwest, desert, pink, or rose locust, is a shrub or small tree in the subfamily Faboideae of the family Fabaceae.
Washingtonia filifera, the desert fan palm, California fan palm, or California palm, is a flowering plant in the palm family Arecaceae, native to the far southwestern United States and Baja California, Mexico. Growing to 15–20 m (49–66 ft) tall by 3–6 m (10–20 ft) broad, it is an evergreen monocot with a tree-like growth habit. It has a sturdy, columnar trunk and waxy, fan-shaped (palmate) leaves.
Fraxinus pennsylvanica, the green ash or red ash, is a species of ash native to eastern and central North America, from Nova Scotia west to southeastern Alberta and eastern Colorado, south to northern Florida, and southwest to Oklahoma and eastern Texas. It has spread and become naturalized in much of the western United States and also in Europe from Spain to Russia.
Fraxinus albicans, commonly called the Texas ash, is a species of tree in the olive family (Oleaceae). It is native to North America, where it is found from eastern Texas and southern Oklahoma in the United States, to the state of Durango in Mexico. Its natural habitat is in dry, rocky slopes, often over limestone.
Fraxinus latifolia, the Oregon ash, is a member of the ash genus Fraxinus, native to western North America.
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 2014 the species is threatened with near total extirpation throughout its range, as a result of infestation by a parasitic insect known as the emerald ash borer.
Fraxinus angustifolia, the narrow-leaved ash, is a species of Fraxinus native to Central Europe and Southern Europe, Northwest Africa, and Southwest Asia.
Fraxinus ornus, the manna ash or South European flowering ash, is a species of Fraxinus native to Southern Europe and Southwestern Asia, from Spain and Italy north to Austria and the Czech Republic, and east through the Balkans, Turkey, and western Syria to Lebanon and Armenia.
Fraxinus mandshurica, the Manchurian ash, is a species of Fraxinus native to northeastern Asia in northern China, Korea, Japan and southeastern Russia.
Fraxinus dipetala, the California ash or two-petal ash, is a species of ash native to southwestern North America in the United States in northwestern Arizona, California, southern Nevada, and Utah, and in Mexico in northern Baja California. It grows at altitudes of 100–1,300 m.
Fraxinus profunda, the pumpkin ash, is a species of ash (Fraxinus) native to eastern North America, where it has a scattered distribution on the Atlantic coastal plain and interior lowland river valleys from the Lake Erie basin in Ontario and New York west to Illinois, southwest to Missouri and southeast to northern Florida. It grows in bottomland habitats, such as swamps, floodplains and riverbanks. It is threatened by the emerald ash borer, an invasive insect which has caused widespread destruction of ash trees in eastern North America.
Fraxinus velutina, the velvet ash, Arizona ash or Modesto ash, is a species of Fraxinus native to southwestern North America, in the United States from southern California east to Texas, and in Mexico from northern Baja California east to Coahuila and Nuevo León.
The Lower Colorado River Valley (LCRV) is the river region of the lower Colorado River of the southwestern United States in North America that rises in the Rocky Mountains and has its outlet at the Colorado River Delta in the northern Gulf of California in northwestern Mexico, between the states of Baja California and Sonora. This north–south stretch of the Colorado River forms the border between the U.S. states of California/Arizona and Nevada/Arizona, and between the Mexican states of Baja California/Sonora.
Celtis reticulata, with common names including netleaf hackberry, western hackberry, Douglas hackberry, netleaf sugar hackberry, palo blanco, and acibuche, is a small- to medium-sized deciduous tree native to western North America.
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a biome found mid-elevations in arid regions of the Western United States, characterized by being an open forest dominated by low, bushy, evergreen junipers, pinyon pines, and their associates. At lower elevations, junipers often predominate and trees are spaced widely, bordering on and mingling with grassland or shrubland, but as elevation increases, pinyon pines become common and trees grow closer, forming denser canopies. Historically, pinyon-juniper woodland has provided a vital source of fuel and food for peoples of the American Southwest.
Quercus turbinella is a North American species of oak known by the common names shruboak, turbinella oak, shrub live oak, and gray oak. It is native to Arizona, California, New Mexico, Utah, Colorado, and Nevada in the western United States. It also occurs in northern Mexico.
Fraxinus parryi, known by common names chaparral ash, crucecilla, and fresnillo, is a species of ash native to southwestern North America, growing as a shrub or a small tree.
