About Coryphantha georgii Boed.
Coryphantha georgii Boed. is a small species of cactus. It typically grows as a single solitary plant, though it may occasionally form small clumps. Its stems are glossy and dark green, and range in shape from flattened globose to club-shaped. Stems grow up to 4 cm (1½ inch) tall and reach approximately 7 cm (3¾ inches) in diameter. The top of the cactus body is woolly, and the species develops a taproot. The surface of the cactus body is deeply divided into many tubercles that resemble closely packed green chili peppers. Each tubercle bears a cluster of slender, stiff spines that grows from a circular structure called an areole. Young areoles are woolly. Each areole produces 8 to 9 thin spines that are white with brown tips. The flowers of this cactus are white. Research-grade observations of Coryphantha georgii mapped on iNaturalist are recorded from the northeastern Mexican states of Tamaulipas, Nuevo León, San Luis Potosí, Guanajuato and Querétaro. This cactus grows at elevations between 1,600 and 2,400 meters (5250-78745 feet). It occurs on volcanic soils of plains and slopes, behind rock walls, in grasslands, and in clearings within oak forests.
