Habitat:

Mammillaria matudae is native to the mountainous regions of Central Mexico, specifically found in the states of Oaxaca, Puebla, and Mexico. It thrives at elevations between 1,500 to 2,300 meters, where the climate is semi-arid with distinct wet and dry seasons. These areas are characterized by rocky terrain with well-draining soils, often composed of volcanic rock and limestone. The natural habitat experiences hot summers and mild winters, with temperature variations that cacti in this region have adapted to. This cactus benefits from the microclimates created by the rugged landscape, where it can find shelter and the optimal balance of sunlight and shade necessary for its growth.

Description:

Mammillaria matudae is a small, columnar cactus that typically grows in clusters, forming dense clumps. Each stem is cylindrical, reaching up to 30 centimeters in height and about 3 to 4 centimeters in diameter. The cactus is covered in tubercles, which are conical and arranged in a spiral pattern. These tubercles are topped with white, woolly areoles from which the spines emerge. The spines are a key identifying feature of this species. Each areole produces about 15 to 20 radial spines that are white and needle-like, measuring approximately 1 centimeter in length. In the center, there are usually one to four central spines that are darker, often reddish-brown, and slightly longer than the radial spines. During the blooming season, typically in late spring to early summer, Mammillaria matudae produces small, funnel-shaped flowers that emerge from the upper part of the cactus. The flowers are a striking pink or magenta color, measuring about 1.5 to 2 centimeters in diameter. These flowers attract various pollinators, which help in the plant’s reproductive process. After pollination, the cactus develops small, club-shaped fruits that are bright red and contain numerous tiny seeds. The overall appearance of Mammillaria matudae, with its dense spine coverage and vibrant flowers, makes it a popular choice among cactus collectors and enthusiasts. Its manageable size and relatively straightforward care requirements also contribute to its appeal.

Cultivation:

Cultivating Mammillaria matudae can be a rewarding experience, provided its specific needs are met. This cactus prefers a well-draining soil mix, which can be achieved by combining standard cactus soil with additional perlite or pumice to enhance drainage. Ensuring good drainage is crucial to prevent root rot, a common issue with cacti in poorly draining soils. When potting Mammillaria matudae, choose a container with drainage holes to allow excess water to escape. This cactus thrives in bright, indirect sunlight. Ideally, it should be placed in a location where it receives plenty of light but is protected from intense, direct midday sun, which can cause sunburn. A south or east-facing window is often suitable. Watering should be done sparingly. During the growing season, from spring to early autumn, water the cactus thoroughly, allowing the soil to dry out completely between waterings. In winter, reduce watering significantly, as the plant enters a period of dormancy and requires less moisture. Overwatering, especially during the colder months, can lead to root rot and other issues. Fertilizing Mammillaria matudae can help promote healthy growth and flowering. Use a balanced, water-soluble fertilizer diluted to half-strength, and apply it once a month during the growing season. Avoid fertilizing in winter, as the cactus’s growth slows down. Mammillaria matudae prefers warm temperatures but can tolerate cooler conditions as long as they are above freezing. Ideal temperatures range from 18 to 24°C during the growing season, with a slight drop at night. In winter, it can handle temperatures down to 10°C if kept dry. Repotting should be done every two to three years, or when the cactus outgrows its pot. When repotting, handle the cactus carefully to avoid damaging the spines and roots. Use fresh, well-draining soil and a slightly larger pot to accommodate growth.

Propagation:

Propagation of Mammillaria matudae is typically done through offsets or seeds. Offsets, or “pups,” form around the base of the parent plant and can be gently removed using a sterile knife. Allow the offsets to dry for a few days before planting them in a well-draining soil mix. Seed propagation is another method but requires more patience. Sow the seeds on the surface of a well-draining soil mix, and lightly cover them with sand or fine grit. Keep the soil moist but not waterlogged, and provide a warm environment with indirect light. Germination can take several weeks.

Curiosity:

Mammillaria matudae is named in honor of the Japanese-Mexican botanist Eizi Matuda, who made significant contributions to the study of Mexican flora. This cactus, like many in the Mammillaria genus, has evolved to survive in harsh conditions, using its spines to provide shade and reduce water loss. Interestingly, the spiral arrangement of tubercles is not just a random pattern but follows the Fibonacci sequence, a mathematical pattern often found in nature.
