  • Posted by Baja_Costero (Baja California - Zone 11b) on Dec 24, 2018 9:59 PM concerning plant:
    Spiny white snowball of a cactus from northeastern Mexico with white or pink flowers. Solitary or often clustering. Stems may grow to 2.5-5.5 inches in diameter and up to 12 inches tall. They are blue-green but obscured by many white spines (8-12 centrals, up to 120 radials). Flowers are pink or white.

    This species was previously (1951) assigned by Franz Buxbaum as the sole member of the genus Mammilloydia, which was kept separate mainly based on seed features (not pitted; lacking perisperm). It has apparently been recombined with Mammillaria, one of the largest genera of cacti.
