Stenocereus thurberi, the organ pipe cactus, [3] is a species of cactus native to Mexico and the United States. The species is found in rocky desert. Two subspecies are recognized based on their distribution and height. The Organ Pipe Cactus National Monument is named for the species. Cacti are minimally adapted to particular thermal niches, and are tremendously vulnerable to seasonal precipitation. [4]
Its English common name is derived from its resemblance to a pipe organ. It is locally known as pitaya dulce, Spanish for "sweet pitaya" or sweet cactus fruit.
This cactus species has several narrow stems that rise vertically, growing from a single short trunk just above the ground level. These stems are about 15 cm (6 in) thick and grow to a height of 5 m (16 ft), however it has been known to reach 7 to 8 m (23 to 26 ft). [5] These stems rarely branch but rather grow annually from the tip of the last growth. The mature plant can reach a width of 3.5 m (12 ft). Each stem has twelve to nineteen 10 mm (3⁄8 in) high ribs that bear dark brown to black spines that turn gray as it matures. It takes 150 years to reach maturity. [5] The older plants produce 75 mm (3 in) funnel-shaped white flowers annually which are open at night and close by the morning and have a purple or pink tint to them. These usually grow during April, May, and June. The organ pipe cactus is usually pollinated by bats. The plant also produces fruit about the size of a tennis ball. Beneath the fruit's spiny exterior is red flesh that has been described as tasting better than watermelon. [6] This fruit has traditionally been harvested by the Seris, who call the plant ool [oːɬ] , and is used as a medicine. [7] [8]
There are two recognized subspecies: [9]
Image | Subspecies | Description | Distribution |
---|---|---|---|
Stenocereus thurberi subsp. littoralis(K.Brandegee) N.P.Taylor | Smaller plant grows around 3 m (10 ft) | southern Arizona, mainland Mexico, and Northern Baja California | |
Stenocereus thurberi subsp. thurberi | Larger Plant | southern Baja California. [7] | |
This species is found mostly in Mexico, mainly in Sonora and southern Baja California and Northern Sinaloa. [10] It is also known to the United States, but is much rarer, with the notable exception of Organ Pipe Cactus National Monument. The plant is predominantly found on rocky hillsides up to 900 m (3,000 ft) in elevation. It is sensitive to frost, so the species is rare in low desert areas, which can be more susceptible to frost. The plant is slow growing, and prefers well-drained soil and full sun. [6] However, when in the seedling stage, it requires shade, and will grow beneath a "nurse tree". It will need this for several years until it grows an adequate root system, which is mostly in the upper 10 cm of soil. [11]
The Sonoran Desert is a hot desert in North America and ecoregion that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the southwestern United States. It is the hottest desert in both Mexico and the United States. It has an area of 260,000 square kilometers (100,000 sq mi).
Barrel cacti are various members of the two genera Echinocactus and Ferocactus, endemic to the deserts of Southwestern North America southward to north central Mexico. Some of the largest specimens are found in the Sonoran Desert.
Stenocereus is a genus of columnar or tree-like cacti from the Baja California Peninsula and other parts of Mexico, Arizona in the United States, Colombia, Costa Rica, Guatemala, Venezuela and the West Indies. The genus has been enlarged by the addition of species from several other genera. A close relative is the peculiar chinoa or chende cactus, Polaskia chende.
Pachycereus pringlei is a species of large 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"; additionally, it is often referred to as sabueso, which is possibly an early Spanish interpretation of the native Seri term for the plant, xaasj.
Stenocereus eruca, commonly known as the creeping devil, is a member of the family Cactaceae. It is one of the most distinctive cacti, a member of the relatively small genus Stenocereus. It is endemic to the central Pacific coast of Baja California Sur, and is found only on sandy soils, where it forms massive colonies.
Echinocereus engelmannii, the strawberry hedgehog cactus or Engelmann's hedgehog cactus, is a cactus commonly found in desert areas of the southwestern United States and the adjacent areas of Mexico, including the states of California, Nevada, Utah, Arizona, Baja California and Sonora.
Selenicereus megalanthus, synonym Hylocereus megalanthus, is a cactus species in the genus Selenicereus that is native to northern South America, where it is known, along with its fruit, by the name of pitahaya. The species is grown commercially for its yellow fruit, but is also an impressive ornamental climbing vine with perhaps the largest flowers of all cacti.
Ferocactus wislizeni, the fishhook barrel cactus, also called Arizona barrel cactus, candy barrel cactus, and Southwestern barrel cactus, is a species of flowering plant in the cactus family Cactaceae, native to northern Mexico and the southern United States. It is a ball-shaped cactus eventually growing to a cylindrical shape, with spiny ribs and red or yellow flowers in summer.
Ferocactus cylindraceus is a species of barrel cactus which is known by several common names, including California barrel cactus, Desert barrel cactus, compass barrel cactus, and miner's compass. It was first described by George Engelmann in 1853.
Stenocereus alamosensis is a species of cactus native to Mexico. It is viviparous, apparently an adaptation to living in coastal plains which are prone to flooding. The Seri people of Sonora call this cactus xasaacoj. The specific epithet, alamosensis, refers to the plant's occurrence at Álamos in the Mexican state of Sonora, in northwestern Mexico.
A pitaya or pitahaya is the fruit of several different cactus species indigenous to the region of southern Mexico and along the Pacific coasts of Guatemala, Costa Rica, and El Salvador. Pitaya is cultivated in East Asia, South Asia, Southeast Asia, the United States, the Caribbean, Australia, Brazil, and throughout tropical and subtropical regions of the world.
Cylindropuntia echinocarpa is a species of cactus known by the common names silver cholla, golden cholla, and Wiggins' cholla. It was formerly named Opuntia echinocarpa.
Stenocereus griseus, also known as the Mexican organ pipe, dagger cactus, pitaya, and pitayo de mayo, is a species of cactus.
Pachycereus pecten-aboriginum is a columnar cactus plant native to Mexico. They can grow up to 15 m (49 ft) high. The trunk of this species is 1.2 to 5.0 m tall and the fruits are large and burr-like. The specific name, pecten-aboriginum, is from the Latin, and means "native combs". It was inspired by the use of the fruits as hair combs.
Flora of the Sonoran Desert includes six subdivisions based on vegetation types. Two are north of the boundary between the United States and Mexico, and four are south of the boundary. The flora of the Colorado Desert are influenced by the environment of the very dry and hot lower areas of the Colorado River valley, which may be barren, treeless, and generally have no large cacti. Flora of the Arizona Upland are comparatively lush, with trees and large columnar cacti that can withstand winter frosts. Those subdivisions of the Sonoran Desert which lie south of the international border are characterized by plants that cannot withstand frost.
Peniocereus striatus is a species of cactus known by several common names, including gearstem cactus, cardoncillo, jacamatraca, sacamatraca, and dahlia-rooted cactus. It is endemic to the Sonoran Desert, where it occurs in Baja California, Sinaloa, and Sonora in Mexico and Arizona in the United States.
