--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>branched or unbranched; branches 0–several, not numerous, seldom rooting. <b>Roots</b> diffuse, upper portion not enlarged. <b>Stems</b> nearly spheric, 2.5–12 × 3.5–7 cm, firm; tubercles 9–10.5(–18) × 3–9 mm; axils appearing naked; cortex and pith not mucilaginous; latex absent. <b>Spines</b> ca. 9–16 per areole, brightly colored than <i>M. grahamii</i>, yellowish, pale pinkish tan, or brown (smaller spines paler), tipped dark chestnut brown to blackish, glabrous, sometimes ± pubescent when young; radial spines (8–)10–15 per areole, bristlelike, 6–10(–12) × 0.13–0.23 mm, stiff; central spines 1(–2) per areole, porrect, hooked, 11–20 × 0.2–0.4 mm; subcentral spines 0(–2) per areole, adaxial to central spines. <b>Flowers</b> (1–)2–3 × 1.2–2 cm; outermost tepal margins densely fringed, fringes 0.4 mm; inner tepals pinkish white with sharply defined magenta midstripes; stigma lobes bright red to red-purple, orange, or magenta, (3–)7–9 mm. <b>Fruits</b> bright orange-red, spheric to obovoid, 5–7 × 4–4.5 mm, level with or beneath spines, juicy only in fruit walls; floral remnant weakly persistent. <b>Seeds</b> black, 1–1.2 × 0.8–1 mm, pitted; testa hard; anticlinal cell walls straight; interstices conspicuously wider than pit diameters; pits bowl-shaped. <b>2n</b> = 22.</span><!--

|discussion=<p>The tendency for all spine hooks on plants to be oriented in same direction is not unique to <i>Mammillaria mainiae</i>. This uncommon and poorly known species is restricted in the flora area to the relatively mesic eastern edge of the Sonoran Desert, in western bajadas of the Baboquivari Mountains, Arizona. <i>Mammillaria mainiae</i> is not known from Nogales, Arizona, contrary to L. D. Benson (1969, 1982); it was originally discovered in Mexico somewhere south of Nogales.</p><!--
--><p><i>Mammillaria wrightii </i>var.<i> wilcoxii</i>, which grows all around Nogales, Arizona, is easily misidentified as <i>M. mainiae</i>.</p>
