A cactus (plural: "cacti", "cactuses", or "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.
Pachycereus is a genus of 9–12 species of large cacti native to Mexico and just into southern Arizona, United States.
 They form large shrubs or small trees up to 15 m or more tall, with stout stems up to 1 m in diameter.

× "Pacherocactus is a genus of shrubby cactus, with only one known species, × "Pacherocactus orcuttii.
 It is a natural hybrid between "Pachycereus pringlei" and "Bergerocactus emoryi", discovered near Rosario, Baja California, Mexico.
 The plant's generic name is formed from those of its parents ("Pachycereus" and "Bergerocactus"); sometimes it can be found listed as "Pachycereus" × "Bergerocactus".
Optics Software for Layout and Optimization (OSLO) is an optical design program originally developed at the University of Rochester in the 1970s.
 The first commercial version was produced in 1976 by Sinclair Optics.
 Since then, OSLO has been rewritten several times as computer technology has advanced.
 In 1993, Sinclair Optics acquired the GENII program for optical design, and many of the features of GENII are now included in OSLO.
 Lambda Research Corporation (Littleton MA) purchased the program from Sinclair Optics in 2001.
Pescatoria is a genus of flowering plants from the orchid family, Orchidaceae.

Pachycereus marginatus is a species of plant in the Cactaceae family.
 (Also sometimes called "Mexican Fencepost Cactus".)
 It has columnar trunks that grow slowly to 12 feet (3.7m) and may reach 20 feet (6.1m) in height.
 Stems are 3 to 4 inches (9–10 cm) in diameter; ribs 5 to 7 inches (13–18 cm).
 Its central spine is about 3/8 inch (1 cm) in diameter with 5-9 radials and slightly yellowish in colour.
 Its cuttings are sometimes used to create a fences as it its spines are not a large or dangerous as some cacti.
Pereskia, as traditionally circumscribed, is a genus of 17 tropical species and varieties of cacti that do not look much like other types of cacti, having substantial leaves and thin stems.
 They originate from the region between Brazil and Mexico.
 Members of this genus are usually referred to as lemon vines, rose cacti or leaf cacti, though the latter also refers to the genus "Epiphyllum".
 The genus is named after Nicolas-Claude Fabri de Peiresc, a 16th-century French botanist.
In the fictional universe of the science fiction television series "Stargate Atlantis", the Genii are a human culture living in the Pegasus galaxy ("see also: Human civilizations in Stargate Atlantis").
 Although they appear to be simple Amish-like farmers, the Genii are an advanced, militaristic society.
 In the series, they have been both enemies and allies to the Atlantis Expedition.
 Nevertheless, Teyla Emmagan believes that outside of Atlantis, they represent the galaxy's best hope of defeating the Wraith.
