Species

Epithelantha (button cactus) is a genus of cactus that is native to northeastern Mexico, and in an area from western Texas to Arizona. Epithelantha has two species, Epithelantha micromeris and Epithelantha bokei. The name Epithelantha refers to the flower position near the apex of the tubercles.[1]

Description[edit]

Epithelantha are very small cacti with globe-shaped or cylindrical stems typically up to one inch in diameter, rarely reaching two inches long. Tiny whitish spines completely cover the surface of the stem. The flowers are also tiny, growing from the tip of the stem. Fruits are bright red.[2]
