Plants solitary and clustering. Stems globose, dark green, 1-8 cm (0.4-3.1 in) high and in diameter. Tubercles not compacted, conical to cylindrical, without latex, some axils with bristles, sparsely woolly. Central spines 0-7, occasionally more, sometimes absent, awl shaped, yellowish to red to dark brown, to 16 mm (0.6 in) long, one or two occasionally hooked. Radial spines 11-32, flattened against the stem sur face to ascending, radiating, usually awl shaped, sometimes hairlike, white to yellow, variably finely pubescent, 6-9 mm (0.2-0.4 in) long. Flowers variable, funnelform, less deep set, yellowish white to white to very pale to pale magenta, rarely magenta, 10-20 mm (0.4-0.8 in) long and in diameter. Fruits globose to ovate, green to bright red. Seeds brownish black, coarsely pitted. Distribution: San Luis Potosí, Zacatecas, Guanajuato, Michoacán, Querétaro, Aguascalientes, and Hidalgo, Mexico. Mammillaria crinita is complex, representing the main eastern phase of Mammillaria series Stylothelae. It is understood only because of extensive fieldwork by W. A. and B. Fitz Maurice (1997b), who believe that three taxa may deserve recognition: subspecies crinita, duweii, and scheinvariana.
Mammillaria crucígera Martius 1832 Mammillaria buchenaui Backeberg 1963 Mammillaria tlalocii Reppenhagen 1989, M. crucígera subsp. tlalocii (Reppenhagen) D. R. Hunt 1997, M. crucígera var. tlalocii (Reppenhagen) Linzenetal. 1998 Mammillaria crucígera var. grandinosa Linzen etal. 1998
Plants solitary or forking into two heads. Stems flattened globose to short cylindrical, olive green to gray-green, to 10 cm (3.9 in) high and 5-6 cm (2-2.4 in) in diameter. Tubercles firm, not sharply angled, keeled, with latex in the growing season, axils with sparse white wool. Central spines 4-5, whitish to waxy yellow to brownish black, rigid, to 2 mm long. Radial spines 16-30, finely needle-like or bristly, white, to 2 mm long. Flowers small, funnelform, purplish pink, rarely rising above the spines. Fruits red. Seeds small, brown.
