About Ariocarpus bravoanus H.M.Hern. & E.F.Anderson
Ariocarpus bravoanus is a fleshy geophytic cactus with gray-green bodies that measure 3 to 9 cm (1.2 to 3.5 in) in diameter, and barely protrude above the soil surface. Its flattened, triangular, somewhat pointed warts project only slightly from the base of the shoot. The species has variable areoles: they sometimes have a woolly furrow running the entire length of the wart, or form a woolly cushion near the tip of the wart. The species produces magenta-colored flowers that reach 2.5 to 5 cm (0.98 to 1.97 in) in diameter. Its mostly light brown fruits are inconspicuous. Ariocarpus bravoanus occurs in xerophytic shrubland on limestone gravel plains in the Mexican state of San Luis Potosí, growing at elevations between 1500 and 2000 meters. It is only known from a small number of localities, and its native habitat is fragmented.
