The saguaro is a columnar cactus that grows notable branches, usually referred to as arms.Over 50 arms may grow on one plant, with one specimen having 78 arms. [6] Saguaros grow from 3–16 m (10–52 ft) tall, and up to 75 cm (30 in) in diameter.
Acanthochronology is the study of cactus spines or Euphorbia thorns grown in time ordered sequence (i.e. in series). Physical, morphological or chemical characteristics and information about the relative order or absolute age of the spines or thorns is used to study past climate or plant physiology.
The nocturnal funnel-shaped white flowers can grow up to 15–20 cm (5.9–7.9 in) long and 13–15 cm (5.1–5.9 in) wide. Pericarp and flower tube with dense white or brown axillary hairs. The round or oblong blue fruits are about 1.3 cm (0.51 in) in diameter and contain black to brown, oval seeds approximately 0.76 mm (0.030 in) long. [3]
Fasciation (pronounced / ˌ f æ ʃ i ˈ eɪ ʃ ə n /, from the Latin root meaning "band" or "stripe"), also known as cresting, is a relatively rare condition of abnormal growth in vascular plants in which the apical meristem (growing tip), which normally is concentrated around a single point and produces approximately cylindrical tissue ...

The cactus family, the Cactaceae, evolved 30–40 million years ago in the Americas, [3] originally completely separately from Africa, Europe, and Asia, although, probably within the last few million years, some species of Rhipsalis appear to have been carried to parts of Asia and Africa, [4] most likely by birds.
The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995.. A study of the growth, movement, reproduction and survival of plants, it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth.
In 1984, the International Organization for Succulent Plant Study set up a working party, now called the International Cactaceae Systematics Group, to produce a consensus classification of the cactus family, down to the level of genus. Their classification has been used as the basis for systems published since the mid-1990s.
