country of origin
Cactus plants are native to tropical and subtropical continents of North and South America and some nearby islands, some of which grow in forests. Most species of succulents are native to South Africa, and only a few are distributed in tropical and subtropical areas of other continents, so South Africa is known as the "treasure house of succulents". From the origin and ecological environment, the above plants can be divided into three categories:
Native to tropical and subtropical arid areas or desert areas. Under the condition of extremely dry soil and air, it survives with the help of water stored in stems and leaves.
Originated in tropical and subtropical alpine arid areas. These areas are short of water, with strong sunshine, strong wind and low temperature. Succulent plants are short, and their leaves are mostly rosette-shaped, or densely covered with wax and fluff, so as to reduce the harm of strong wind and strong light in mountainous areas and reduce excessive transpiration.
Native to the tropical rain forest. These species do not grow in soil, but attach themselves to the rocks of tree trunks and shadow valleys. Its ecological habits are close to epiphytic orchids.
The medicinal method is to use the whole herb as medicine. It can be harvested all year round. Fresh or sliced and dried.
Functions: clearing away heat and toxic materials, removing blood stasis and swelling, invigorating stomach and relieving pain, and relieving cough.

Zygocactus trurncatus cactus
The plural is cacti or cactus. Ceres is just a kind of cactus, not a general term for cactus. There are many kinds of cacti, such as Poria cocos, the largest cactus in the world, and Blossfeldia liliputiana, the smallest cactus in the world.
A family of dicotyledonous flowering plants (characterized by having two cotyledons). It belongs to Dianthus. Some authoritative organizations list cactus as an order with only one family-Cactuidae. Botanists estimate that there are 130 genera of cactus, about 1650 species.
Cactus is native to North and South America, from British Columbia and Alberta to most parts of the south; Its southern border extends to Chile and Argentina. Mexico has the largest variety of cacti. Only Rhipsalis may be native to the Old World and distributed in East Africa, Madagascar and Sri Lanka. However, many scholars believe that this genus was introduced to these areas from other parts of the world.
Cactus is a succulent perennial. Although a few species live in tropical or subtropical areas, most of them live in areas that adapt to drought. The stem of cactus is usually thick and contains chlorophyll, grass or wood. Most kinds of leaves either disappear or are extremely degraded, thus reducing the surface area of water loss, while photosynthesis is replaced by stems. Only tropical Schizophyllum and Schizophyllum have obvious functional leaves. Roots are usually slender, fibrous, shallow and widely distributed, and are used to absorb surface water.
The size and shape of cactus plants vary greatly, from button-shaped Peott palm (Lophophora), short and rough Rosa roxburghii (Opuntia) and hedgehog palm (Echinocereus) to tall cylindrical barrel palms (Ferocactus and Echinocactus). Most cacti grow in soil, but some tropical species, including Corydalis, Epiphyllum and Schlumberger, are epiphytes. Others grow on hard surfaces, such as rocks. The stems of epiphytes are usually thin and flat. The surface morphology of plants is also different, either smooth or with prominent nodules, ridges or grooves.
The cactus is different from other succulent plants in that its stem has a cushion-shaped structure-community. In almost all kinds of communities, thorns or barbs will grow, from which flowers, branches and leaves (if any) will be born.
The internal structure of the stem of Golden Red Cactus (Opuntia dillenii) is consistent with other dicotyledonous plants, and there is a cambium between the internal xylem and the external phloem. However, stems are mostly composed of thin-walled storage cells, which contain mucilage, which can protect plants from losing water. The stem of cactus is the main organ for producing and storing nutrients.
A few cactus species can produce small plants near the ground level, so as to reproduce asexually. The tissues of various cacti are quite consistent, so the terminal part of one cactus can be grafted to the top of another cactus.
But cacti mainly reproduce through seeds. The flowers of cactus are usually large and gorgeous, and most of them are solitary. All genera have flower tubes (composed of perianth segments, calyx and petals are obviously different or indistinguishable), and the ovary is inferior and one room. There is a style on the ovary, and there are many stigmas at the top of the style to receive pollen. After pollination and fertilization, the ovule develops into seeds (multiple seeds) and the ovary develops into fruit (usually berries). Pollen is carried by wind or birds. Shortly after pollination, the flower tube falls off from the top of the ovary, leaving obvious scars.
Cactus is widely cultivated as an ornamental plant. In addition, Rosa roxburghii (immortal fruit) and Cioglia palm (both cactus) are also edible plants. In South America, cactus, wax cactus and other species are used as living fences, and in some desert areas, wooden columnar cactus is used as fuel. Barrel palm (cactus and cactus) is the water source in an emergency. Lophophora williamsii is a palm with hallucinatory effect, which has been used in some ceremonies since Columbus arrived in America.
Cactus is a big family with at least two thousand members. Its hometown is in America and Africa, especially Mexico, and it is called "cactus kingdom", and cactus is praised as "Xiantao" by Mexicans. China Yunnan minority areas also have the habit of taking cactus fruit as fruit. There is a beautiful legend in the local area: a huge Shan Ying flies around looking for a place to live with a snake in its mouth. When it landed on a cactus full of yellow flowers, it never wanted to leave. Since then, Mexicans have established their home in this vibrant place-Mexico City. The design of the Mexican national emblem is based on this legend.
