1. Origin of Name:

The genus "Discocactus" derives from Latin roots—"disco," meaning "disk," and "cactus," referring to its flat, disc-shaped form. The species "crystallophorus" combines "crystallus" (Latin for "crystal") and "phoros" (Greek for "bearing" or "carrying"), describing the plant’s striking, glassy, or crystalline appearance of its spines and surface. The form "HU 582 Minas Gerais" indicates a specific collection or locality—specifically from Minas Gerais, Brazil—where this particular variant was found or cultivated. Its name highlights its distinctive, sparkling, and jewel-like qualities, reminiscent of crystals embedded in a cactus.

2. Origin of Plant:

Discocactus crystallophorus Form HU 582 originates from the rocky, rugged terrains of Minas Gerais, Brazil. Found in high-altitude, arid environments, this cactus has adapted to survive in poor, well-drained soils with intense sunlight and temperature extremes. It was collected as part of botanical expeditions in Brazil, with "HU 582" referencing a specific collection number or locality, illustrating its regional and specific genetic origin.

3. Description:

This distinctive, flat, disc-shaped cactus typically measures 4-8 inches in diameter. Its surface appears smooth and polished, often reflecting light like glass or crystal, giving it a gem-like appearance. The plant is covered with numerous small, tubercles or areoles bearing tiny, radiating spines or hair. In spring or summer, it produces small, bright yellow or white flowers at the edges, which add a splash of color to its reflective surface. The plant’s unique, crystalline visual effect, coupled with its compact, disk-like form, makes it a captivating centerpiece, especially for collectors interested in unusual, tactile succulents.

4. Conservation Status:

While not widely endangered, wild populations of Discocactus crystallophorus can be vulnerable due to habitat loss and illegal collection. Focusing on responsible cultivation, propagation, and habitat preservation in Brazil helps ensure its survival and continued appreciation in cultivation.

5. Care:

For successful cultivation of Discocactus crystallophorus Form HU 582:

• Watering: Water sparingly, allowing the soil to completely dry out between waterings. Reduce water during winter rest.
• Soil: Use a very well-draining cactus or mineral-based soil mix, with added coarse sand, pumice, or gravel.
• Light: Requires full sun or bright, direct sunlight for at least 4-6 hours daily to maintain its reflective surface and promote flowering.
• Temperature: Prefers warm temperatures between 60°F (15°C) and 90°F (32°C). Protect from frost — bring indoors or provide winter warmth in cooler areas.
• Tips: Fertilize lightly during the growing season with a cactus fertilizer. Monitor for pests like scale or mealybugs.

Discocactus crystallophorus Form HU 582 from Minas Gerais is a mesmerizing, jewel-like cactus that captivates with its crystalline surface and elegant form. Its unique, reflective appearance and regional rarity make it a prized addition for cactus enthusiasts seeking a tactile, luminous desert gem that embodies the natural artistry of Brazil’s arid landscapes.
