Pachycereus pringlei, also known as Mexican giant cardon or elephant cactus, is a species of cactus native to northwestern Mexico in the states of Baja California, Baja California Sur, and Sonora. It is commonly known as cardón, a name derived from the Spanish word cardo, meaning "thistle". [2]

Cactus Family of mostly succulent plants, adapted to dry environments

A cactus is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word "cactus" derives, through Latin, from the Ancient Greek κάκτος, kaktos, a name originally used by Theophrastus for a spiny plant whose identity is not certain. Cacti occur in a wide range of shapes and sizes. Most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water. Almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of leaves, enlarged stems carry out photosynthesis. Cacti are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north—except for Rhipsalis baccifera, which also grows in Africa and Sri Lanka.

Mexico Country in the southern portion of North America

Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world. With an estimated population of over 120 million people, the country is the tenth most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.

Baja California Federal entity in Mexico

Baja California, officially the Free and Sovereign State of Baja California, is a state in Mexico. It is the northernmost and westernmost of the 32 Federal Entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of Baja California. It has an area of 70,113 km2 (27,071 sq mi), or 3.57% of the land mass of Mexico and comprises the northern half of the Baja California Peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean, on the east by Sonora, the U.S. state of Arizona, and the Gulf of California, and on the south by Baja California Sur. Its northern limit is the U.S. state of California.

Large stands of this cactus still exist, but many have been destroyed as land has been cleared for cultivation in Sonora.

The fruit of this cactus was an important food for the Seri people in Sonora, who call the cactus xaasj. [3]

Seri people ethnic group

The Seri are an indigenous group of the Mexican state of Sonora. The majority reside on the Seri communal property, in the towns of Punta Chueca and El Desemboque on the mainland coast of the Gulf of California. Tiburón Island (Tahejöc) and San Esteban Island were also part of their traditional territory. They were historically seminomadic hunter-gatherers who maintained an intimate relationship with both the sea and the land. They are one of the ethnic groups of Mexico that has most strongly maintained their language and culture throughout the years after contact with Spanish and Mexican cultures.

The flesh of this cactus contains alkaloids, and may have been used as a psychoactive plant in Mexico. [4]

Alkaloid class of naturally occurring chemical compounds

Alkaloids are a class of naturally occurring organic compounds that mostly contain basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.

Psychoactive drug chemical substance that affects brain function or perception

A psychoactive drug, psychopharmaceutical, or psychotropic drug is a chemical substance that changes brain function and results in alterations in perception, mood, consciousness, cognition, or behavior. These substances may be used medically; recreationally; to purposefully improve performance or alter one's consciousness; as entheogens; for ritual, spiritual, or shamanic purposes; or for research. Some categories of psychoactive drugs, which have therapeutic value, are prescribed by physicians and other healthcare practitioners. Examples include anesthetics, analgesics, anticonvulsant and antiparkinsonian drugs as well as medications used to treat neuropsychiatric disorders, such as antidepressants, anxiolytics, antipsychotics, and stimulant medications. Some psychoactive substances may be used in the detoxification and rehabilitation programs for persons dependent on or addicted to other psychoactive drugs.

A symbiotic relationship with bacterial and fungal colonies on its roots allows P. pringlei to grow on bare rock even where no soil is available at all, as the bacteria can fix nitrogen from the air and break down the rock to produce nutrients. The cactus even packages symbiotic bacteria in with its seeds. [5] [6] [7]

Symbiosis type of a close and long-term biological interaction between two different biological organisms

Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, may be of the same or of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens; biologists have now abandoned that restriction.

Nitrogen fixation is a process by which nitrogen in the air is converted into ammonia (NH3) or related nitrogenous compounds. Atmospheric nitrogen, is molecular dinitrogen (N2), a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation converts N2 into ammonia, which is metabolized by most organisms.

Morphology

Cardon is the tallest cactus species in the world, with a maximum recorded height of 19.2 m (63 ft), [8] with a stout trunk up to 1 m (3.3 ft) in diameter bearing several erect branches. In overall appearance, it resembles the related saguaro (Carnegiea gigantea), but differs in:

Saguaro species of plant

The saguaro is an arborescent (tree-like) cactus species in the monotypic genus Carnegiea, which can grow to be over 40 feet (12 m) tall. It is native to the Sonoran Desert in Arizona, the Mexican State of Sonora, and the Whipple Mountains and Imperial County areas of California. The saguaro blossom is the state wildflower of Arizona. Its scientific name is given in honor of Andrew Carnegie. In 1994, Saguaro National Park, near Tucson, Arizona, was designated to help protect this species and its habitat.

Its flowers are white, large, nocturnal, and appear along the ribs as opposed to only apices of the stems.

Lifespan and growth

An average mature cardon may reach a height of 10 metres (30 ft), but individuals as tall as 18 metres (60 ft) are known. [9] It is a slow-growing plant [10] with a lifespan measured in hundreds of years, but growth can be significantly enhanced in its initial stages by inoculation with plant growth-promoting bacteria such as Azospirillum sp. [11] [12] [13] Most adult cardon have several side branches that may be as massive as the trunk. The resulting tree may attain a weight of 25 tons. [14]

Notes

1. ^ The tallest living cactus is a specimen of pachycereus pringlei. The tallest cactus ever measured was an armless Saguaro cactus which blew over in a windstorm in 1986; it was 78 feet tall. [15]

They tend to grow in non calcareous dry granite-based soil but can also grow in rocky habitats, either in rock fissures or directly on top of the rock surface even without the presence of soil. Thus, the mineral composition of the rocks in their habitat directly influence their abundance. The habitat of Mammillaria fraileana is home to succulent flora and is particularly rich in local endemics. Currently, no major threats to the species are known to exist.
