Juniperus pinchotii

Juniperus pinchotii is a plant belonging to the family of the cypress family ( Cupressaceae ). It is native of the southern United States and northern Mexico.

Description

Can Juniperus pinchotii grows as evergreen shrub or small tree of the stature heights of up to 6 meters reach. Usually, the species forms from several strains with diameters of up to 20 centimeters. The crown is flat globose to irregular shaped and is formed by just making or ascending branches. The smooth, ash-gray to brown Stammborke is fibrous with age and peeling off in long strips. The smooth bark is peeling off at the branches in strips or flakes. The bark of the rigid, approximately 5 to 10 millimeters thick in cross-section and three or four angular sectors is smooth.

The species forms from both needle-like and scale-like leaves, both of which can occur simultaneously on a tree. The scale-like shape is most common. All the leaves are colored green, have a finely toothed leaf margin and on the underside of leaves elliptic to oblong glands, many of which secrete an aromatic fragrant, white substance. The needle-like leaves are 4-6 mm long and have no blue-green color on the upper leaf surface. The scale-like leaves are 1 to 2 millimeters long. Your tip is tapered and they mostly do not overlap, or only up to a fifth of its length.

Juniperus is pinchotii dioecious - getrenntgeschlechtig ( dioecious ) and berry cones mature within one year. The juicy, not resinous and sweet-tasting berry cones have formed a straight stem and are at a thickness of 6 to 10 mm spherical to ovoid. They are copper-colored copper- colored to maturity out. Each of the journal carries one to two, 4-5 mm large seeds.

Distribution and location

The natural range of Juniperus pinchotii includes the southern United States as well as northern Mexico. In the U.S., one finds the kind in southeastern New Mexico, Oklahoma and Texas. In Mexico, the distribution area includes the states of Chihuahua, Coahuila, Durango, Nuevo Leon, Sonora, Tamaulipas, and Zacatecas.

Juniperus pinchotii thrives at altitudes 300-1700 m. One finds the way, especially on low hills and in ravines where it grows on gravelly limestone soils and on chalky soils. There are often formed mixed stands with the Honey Mesquite ( Prosopis glandulosa ) and Quercus turbinella.

Ecology

The seeds are able to survive fires and germinate only after the fire. The mature plants are to be formed new shoots in a position after a fire.

System

The first description as Juniperus pinchotii was in 1905 by George Bishop Sudworth in Forestry and Irrigation, Volume 10, page 204 synonyms for Juniperus pinchotii Sudw. are Juniperus monosperma var pinchotii ( Sudw. ) Melle, Juniperus texensis Melle and Sabina pinchotii ( Sudw. ) IM Lewis.

The species is divided into up to two varieties: Juniperus var pinchotii pinchotii the nominate Juniperus is pinchotii var erythrocarpa ( Cory ) Silba has bright red colored berry cones. A synonym is Juniperus erythrocarpa Cory.

Juniperus pinchotii forms natural hybrids with the red berry juniper (Juniperus coahuilensis ).
