    Small, profusely clumping Mammillaria from northwestern Oaxaca with whitish flowers (with brownish red midveins) and striking globose red fruit (an unusual shape for the genus) to about 1cm wide. Described in 1975. Named for Felipe Otero. Found in high altitude (~2000m) forests. Stems to 1.6 inches in diameter, 1 inch high. Strongly hooked central spine. Wooly or hairy axils. Offsets are easily separated, and regular removal favors growth of the main stem. Pollinated by insects. Conservation status: Vulnerable.
