First, winter clouds
In 2000, the genus Pyrrhus was discovered in the state of San Luis, north of Las Palomas, Mexico (map number 20).
Number 20
Winter clouds grow slowly, the plant protrusions barely exceed the soil level by almost 1 cm, and the overall appearance is brown, without showing any green tendency. The slow growth of winter clouds also attracts some lovers of delicate plants. The flowers of the winter cloud range from white to light brown with a little dark brown in the middle. It is recommended to use a mixture of alkaline, gravel soils for growing mediums, with watering to ensure that the soil is sufficiently dry between waterings (see Dry see Wet).
In the wild state, the delicate genus is a winter cloud
Second, Jiaoliyu
Found in Las Tablas, San Luis, Mexico, unlike most plants that grow on cliffs, it grows in flat areas with habitats similar to where rock peonies are found, giving the impression that they may stay in the water for a while when it rains, although there are local records that although the surrounding countryside sometimes floods, the plants remain above the water level. When we found them, these plants were completely one with the ground, and they resembled black feather jade when they flowered, and the flowers were white and pale pink. Plants found in cultivation are particularly sensitive to over-watering and are prone to death. Given their habitat, a mixture of very sandy, alkaline soils would grow better. want
Genus Quince - Udonna in the wild state
Use very coarse granular sand, so that the drainage is better.
Petrite grows low, flattened to hemispherical, solitary, light gray-green, dark green, or blue-gray to dark gray to green, with very thick roots, flowers white or yellowish to white, rarely powdery, sometimes dark pink, the fruit is green, red, or brown, the seed is black, 1.2 mm in diameter. Can be combined with other agave, rock peony and other plants, Jade grows in flat areas, accompanied by some trees or shrubs, growing in soils containing calcium carbonate ingredients (calcium carbonate content of up to 98%), covered with hard, porous limestone, up to several meters thick.

Third, the Great Wall Pill
The Great Wall Pill was found in the Mexican states of Queretaro (24), Bernal and Mesard león. The plant's unique curly spines make it a popular cultivated plant, growing easily compared to some of its lighter-colored counterparts, and the flowers are usually brightly colored. Although general growing mediums can also be cultured, alkaline, grit-like soil mixtures are recommended for best results. Great Wall Pills are occasionally clumped, spherical to short cylindrical in shape, pale green to dark blue-green or gray-green, 2–4 cm thick and 2.5–3.5 cm wide. The spines are 15–30 mm long, radial or centrally distributed, mostly erect, and particularly dense at the growth points. The flowers are white, reddish-purple, yellowish-green or pink, the fruit is green or brown, and the seeds are black, 1.3–1.5 mm. The Great Wall Pill inhabits limestone rubble and regolith stones.

There are many subspecies of great wall pills: subspecies 1: ssp. krainzianus (growing environment reference subspecies 2 ssp minimus, not introduced here)
Subspecies 2: ssp. minimus
Coming from the Mexican state of Hdalgo (map 25), near a place called lxmiquilpan, it grows in rock crevasses. The species can be rapidly acquired from seed or commercial production and can rapidly grow into a narrow column with a total length of about 3 or 4 cm and a width of no more than a few millimeters, gradually widening. The flowering period begins within two years of sowing. In cultivation, the growth of the first few years is not difficult, but once mature, it is even more difficult to continue to grow. Careful watering should be done to add a fairly high percentage of gravel or limestone debris to the soil mixture to help keep the soil growing. It is described that its stem is 8-12 mm in diameter and 15-20 mm in total length, with roots as thin as carrots, 40-60 mm long, flowers yellow, it seems to differ only in stem and root size; the fruit is green to pink, then brown, and the seeds are black, 1.2-1.5 mm.
