Coryphantha georgii is a species of cactus that is endemic to Mexico. [2]
Coryphantha georgii is a small cactus species that grows solitary, although it can sometimes form small clumps. The glossy, dark green stems range from flattened globose to club shaped, and measure up to 4 cm (1½ inch) tall and about 7 cm (3¾ inches) in diameter. The body's top is woolly, and the cactus develops a taproot. [3]
The body surface is deeply divided into numerous tubercles looking like closely packed, green chili peppers. Atop each tubercle arises a cluster of slender, stiff spines, from a spot called the areole. The areoles are circular, and woolly when young. Arising from the areoles are 8 to 9, thin spines which are white with brown tips. The flowers are white. [3]
The iNaturalist distribution map for Coryphantha georgii shows research-grade observations in the northeastern Mexican states of Tamaulipas, Nuevo León, San Luis Potosí, Guanajuato and Querétaro. [4]
Coryphantha georgii grows at elevations of 1,600 to 2,400 meters (5250-78745 feet) on volcanic soils of plains and slopes, behind rock walls, in grasslands and in clearings of oak forests. [5]
Coryphantha georgii was described by the German botanist Friedrich Bödeker and first published in the scientific journal Monatsschrift der Deutschen Kakteen-Gesellschaft 3: 163 in 1931. [2]
The genus name Coryphantha is derived from the Greek coryphe, meaning 'top' or 'head', plus anthos meaning 'flower'; this combination refers to the flowers' location at the apex of the stems. The term georgii honors the cactus collector Erich Georgi of Saltillo, Mexico. [6] [7]
The Red List of Threatened Species of the IUCN classifies Coryphantha georgii as a Species of Least Concern. [1]
