C. forbesii is a columnar, branching, colony-forming cactus which can grow up to 3 m (9 ft 10 in) in height, with a mature circumference of around 15 cm (5.9 in); however, due to weather, natural breakage, self-propagation and other growth-limiting factors, it is more frequently observed at a height of about 2 m (6 ft 7 in). Larger specimens ...
Cereus are shrubby or treelike, often attaining great heights (C. hexagonus, C. lamprospermus, C. trigonodendron up to 15 metres or 49 feet). Most stems are angled or distinctly ribbed, ribs 3–14 centimetres (1 + 1 ⁄ 4 – 5 + 1 ⁄ 2 inches) long, usually well developed and have large areoles, usually bearing spines.
The generative spiral is a consequence of the same process that produces the clockwise and counter-clockwise spirals that emerge in densely packed plant structures, such as Protea flower disks or pinecone scales. In modern times, researchers such as Mary Snow and George Snow [13] continued these lines of inquiry. Computer modeling and ...
Astrophytum is a genus of six species of cacti, native to North America. [2]These species are sometimes referred to as living rocks, though the term is also used for other genera, particularly Lithops ().
It is also known as giant club cactus, hedge cactus, cadushi (in Papiamento and Wayuunaiki [2]), and kayush. Cereus repandus is grown mostly as an ornamental plant, but has some local culinary importance. The Wayuu from the La Guajira Peninsula of Colombia and Venezuela also use the inner cane-like wood of the plant in wattle and daub ...
This cactus is a species of tree [4] which grows up to eight feet (2.4 m) tall. The stem segments are up to 40 centimeters long and are "copiously armed" with pink spines which can exceed 12 centimeters in length. The spines on the trunk all point downward and are the largest spines on the plant.
Epiphyllum (/ ˌ ɛ p ɪ ˈ f ɪ l əm /; [3] "upon the leaf" in Greek) is a genus of epiphytic plants in the cactus family (Cactaceae), native to Central America and South America.

The Columbia Plateau cactus grows in big sagebrush and lower montane dry habitats in eastern Washington and Oregon and extending into Idaho in dry regions, steppes and semi-deserts on hills or rocky outcrops at altitudes between 260 and 1,200 metres (850 and 3,940 ft). [3] [1] [5] It grows in scattered locations but is often locally abundant. [5]
