Ehretia Anacua (Terán & Berland.) I.M. Johnst.

“Anacua”

This medium-sized tree is found in eastern Mexico and southern Texas in the United States. It is a member of the borage family, Boraginaceae. Its most common name is “Anacua,” derived from the Mexican Spanish word, “anacahuite.” It is also known as sandpaper tree. It is found on dry hillsides as a shrub, but reaches tree size in the moist soils of riparian zones and floodplains. It can be found at elevations from sea level to 300 m. This tree reaches between 6.1 – 13.7m in height and a diameter of 0.3 m., often producing suckers or multiple trunks. Its bark is reddish-brown to gray with narrow furrows and peeling scales. Its leaves are dark green, elliptical or ovate. Their upper surfaces are remarkably rough, feeling like low-grade sandpaper. This species is partial evergreen, replacing some of its leaves in early spring. Abundant white flowers form in panicles at the ends of twigs, making trees appear to be covered in snow when in bloom from spring to summer. An “Anacua” can live up to 50 years.

Eysenhardtia polystachya (Ortega) Sarg. “Palo azul”

This tree species belongs to the Fabaceae family and is native to North America. Its distribution goes from Arizona through north and central Mexico, down south to Oaxaca.
It is commonly known as, “Palo azul,” “Palo dulce,” or “Taray.” In the United States it is known as “Kidney wood.” This tree grows along forest edges and water courses at elevations of 150 – 3000 m. Its bark is used as a source of lignum nephriticum which has diuretic properties. It is also used as forage for animals.

Picea engelmannii Parry ex Engelm.

“Pícea de Engelmann”

This is a medium-sized to large evergreen tree belonging to the Pinaceae family. It is native to North America extending to the north of Mexico. It is known as “Pícea de Engelmann.” This species grows to 25 – 40 m tall, exceptionally to 65 m tall, with a trunk diameter of up to 1.5 m. Its reddish bark is thin and scaly, flaking off in small circular plates 5 – 10 cm across. The crown is narrow conic in young trees, becoming cylindric in older trees. The shoots are buff-brown to orange brown, usually densely pubescent, and with prominent pulvini. Its leaves are needle-like, long, flexible, rhombic in cross-section, glaucous blue green above, with several thin lines of stomata, and blue white below with two broad bands of stomata. The needles have a pungent odor when crushed.

Pinus arizonica Engelm. “Pino de Arizona”

This is a medium-sized pine native to northern Mexico, southeast Arizona, southwest New Mexico, and western Texas in the United States. It grows at elevations of 1300 – 3000 m. In English it is commonly known as “Arizona pine” while in Spanish it is commonly known as “Pino de Arizona” or “Pino amarillo.” This tree reaches between 25 – 35 m in height with a trunk diameter of up to 1.2 m. Its needles appear in bundles of 3, 4, or 5, with 5-needle fascicles being the most prevalent. Its cones are single, paired, or in whorls of three, and 5 – 11 cm long. This pine is a source of construction timber and is heavily harvested for firewood. Extensive cutting has reduced the formerly widespread of “Pino de Arizona” forests, particularly in Mexico.

Pinus pinceana Gord. “Piñon”

This tree species is a conifer belonging to the family Pinaceae. Its common names in Spanish are: “Piñon,” “Pino piñonero-llorón,” and “Pince piñon.” This species is native to Mexico, it is found in the states of Durango, northern Coahuila, central San Luis Potosí, and southern Querétaro and Hidalgo.
It grows in semi-arid mountains at altitudes between 1,100 – 2,600 m. This tree isusually small appearing as a large shrub; it usually reaches between 5 – 6 m in height, but occasionally may reach up to 10 m. Its seeds are edible but produced infrequently. It is used as wood and firewood.

Populus deltoides W.Bartram ex Marshall

“Alamo negro”

This is a cottonwood poplar tree native to North America and northeastern Mexico. Commonly known as “Alamo negro de Norteamérica.” It is a large tree reaching between 20 – 30 m in height and with a trunk diameter of up to 2.8 m. It is one of the largest North American hardwood trees. It has a straight trunk, its leaves are large, deltoid (with a triangular form). Its bark is silvery-white, smooth or lightly fissured when young, becoming dark gray and deeply fissured on old trees. It is a dioecious species, which flowers are produced on single-sex trees in early spring. These trees normally live between 70 to 100 years.

Quercus virginiana Mill. “Encino siempre verde”

This is an evergreen oak tree endemic to the Southeastern United States and the north of Mexico. In Spanish it is known as “Encino siempre verde” or “Encina del sur.” It reaches between 15 – 20 m in height, occasionally reaching up to 25 m. An adult tree trunk may reach up to 1.2 – 2 m in diameter next to the base. Its bark is dark, thick, and furrowed longitudinally. The leaves are stiff and leathery, with the tops shiny dark green and the bottoms pale gray. The male flowers are yellow green. The acorns are small, oblong in shape, shiny and tan-brown to nearly black,often black at the tips, and borne singly or in clusters. This tree has a deep taproot that anchors it when young and eventually develops into an extensive and widespread root system. This, along with its low center of gravity and other factors, makes it extremelyresistant to strong sustained winds, such as those seen in hurricanes.

Aspidosperma quebracho – blanco

Schtlr.

“Quebracho blanco”

This tree is characteristic of the Chaqueña region in Argentina; which goes from the northern border to the northeast of San Juan, north of San Luis, Córdoba and Santa Fe, crossing the Paraná river in the provinces of Corrientes and Entre Ríos. Its distribution reaches Bolivia, Paraguay, and Uruguay. The “quebracho blanco” in its optimal zone reaches 20 to 25 m in height and up to 1 m in diameter. Its wood is hard and heavy. Its bark is rich in tannins and alkaloids. In popular medicine it has been used to fight malaria.
