Family of cactus. Homeland - Brazil, Paraguay, Bolivia and Argentina. The name of the genus comes from the Greek "cactus from the south". Now most of the species of this genus are united in the genus Parodia Parodia. Since the name Parodia was used before the Notocactus, it took precedence and almost all Notocactus became Parodies.
The taxonomy with cacti and notocactus, in particular, is very complicated. Either they were singled out in a separate genus, then they were counted as parodies, but according to the latest data from The Plant List (The current list of all known plant species, compiled in cooperation with the largest botanical gardens in the world (Royal Botanic Gardens, Kew and Missouri Botanical Garden), the genus Notocactus is an independent genus, but only one species, Notocactus horstii (F. Ritter) K. Herm.
Notocactus horsti Notocactus horstii is a spherical, slightly flattened cactus, at a young age, at a height of about 10 cm, the diameter is almost 15 cm, an almost spherical trunk gradually extends. The flowers are orange, yellow, pink, about 3.5 cm in diameter. Central spines from 1 to 6, yellow-brown, straight, even or slightly curved, 8 to 30 mm long. Radial spines 10-15 linear whitish or light brown, 6-30 mm long in different forms. The flowers are yellow-orange, reddish or purple, 3-4 cm in diameter.

Caring for Notocactus
Temperature: Normal in summer, it is better to keep the cacti outdoors in a place protected from rain, for example, under a transparent canopy (transparent umbrella). The difference between night and day temperatures is beneficial. In winter, a dormant period at a temperature of 7-10 ° C, at least 5 ° C, with a dry content (experienced florists can control it up to + 1 + 2 ° C).
Lighting: Bright lighting. Notocactus like a lot of light, but you need to get used to the spring sun gradually to avoid burns, especially if the wintering was cold and dark.
Watering: Abundant in the cactus sense in spring and summer, at temperatures above 22-24 ° С, i.e. after the soil has completely dried the next day or every other day. Since autumn, watering is reduced, with a cold snap, when the temperature is below 20 ° C, watering is less and less, after the soil dries out, you need to wait 5-7 days. Colder - even less often, avoiding only strong shrinkage of the cactus stem (about once a month).
Fertilizer: From March to July, they are fed with a special fertilizer for cacti once a month. Do not use regular indoor plant fertilizers, they can contain too much nitrogen, even when diluted.
Air humidity: Notocactus are resistant to dry air, do not need to be sprayed.
Transfer: Soil - 1 part of leafy soil (or universal peat soil, for example Terra Vita living earth), 1 part of sand or fine gravel (2-3 mm). Young plants are transplanted annually or every year, old ones - as needed. The substrate should have a slightly acidic reaction. Choose shallow but wide pots. Most Notocactus have long thorns, so position the pots so that the plants don't hurt each other. It is advisable to make the upper drainage so that the lower part of the cactus stem does not come into contact with the wet soil after watering.
Reproduction: Seeds and children. Seeds are sown in moist sterile soil (a mixture of peat and coarse sand), germination at a temperature of 24-26 ° C. Mandatory airing of seedlings, moisturizing as it dries. As soon as the shoots appear, the best lighting is possible.
