Cactus
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of ''Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, 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 ...

Matucana
''Matucana'' is a genus of cacti (family Cactaceae), containing approximately 20 species of mostly globular plants. The genus is known only from Peru, mostly along the Marañón River. Some species are endangered due to collection for the specialist market. Description Plants within this genus may be identified by the distinctive structure of their fruits, which are marked by vertical splits that release their seeds upon maturity. The overall body shape, spination, offset production, and preferred habitat exhibit considerable variability, mirroring the diverse nature of the flowers within the genus. Species of ''Matucana'' have low, globose or shortly cylindrical bodies, either solitary or clustering. The flowers are subapical, usually more or less zygomorphic, diurnal, of various colours, but usually red, yellow or pink. However, a few species, notably ''M. oreodoxa'', have actinomorphic flowers and were placed in a separate genus - ''Eomatucana'' - by F. Ritter. They are ...

Matucana Haynii
''Matucana haynii'' is a species of ''Matucana'' found in Peru. Description ''Matucana hayneii'' grows solitary or in sprouts with spherical to broadly cylindrical, with green shoots and reaches a height of up to with a diameter of . There are 14 to 30 tuberculate ribs. The variable white to light brown spines turn gray with age. The one to 20 central spines are and the 14 to 45 radial spines long. The mostly crooked flowers are crimson to salmon pink to a little crimson. They are long and have a diameter of up to . The spherical to club-shaped, reddish green fruits are long and reach the same diameter.

Endemic Flora Of Peru
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
