The stem is subglobular (flattened in the upper part) often spineless when old and up to 2 inches (5 cm) in diameter. The spines are up to 0.2 inch (5 mm) long, spreading, flattened against the tubercles and pectinate, and not intertwining with those of the other areoles, yellowish, white or pale coffee colored. The flowers are funnel form at the plant apex, that open during the hours of sun, pericarpel with small scales and wool, floral tube with abundant bristles, tepals pale colored (whitish, yellow, pinkish or orangish).

How to Grow and Care
Eriosyce requires strong sun exposure to develop good spinal growth, but tolerate light shade. Some light shadow my be useful in the hottest summer days.
A rich, fast-draining cactus mix is ideal. Good drainage is essential for health.
During the summer, water the cactus every two weeks or slightly less often, depending on how moist the soil remains. In the winter rest period, cut watering back to once a month, or in humid areas, not at all. One of the key factors in success with these cacti is avoiding any hint of wet soil. Because their root systems are weak, they are especially prone to root rot, which will eventually kill your plant.
During the summer, regular doses of a cactus fertilizer will help it grow its best. Use diluted fertilizer for best results. – See more at: How to Grow and Care for Eriosyce
