--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>unbranched, except in old age, ultimately forming dense clumps, 5–20(–30) cm diam., stem not obscured by spines when hydrated, obscured when desiccated. <b>Roots</b> short, fleshy, enlarged taproots, basally ± 1/3–1/2 of stem diam. <b>Stems</b> deep-seated, aerial parts inconspicuous, flat-topped to hemispheric (to ovoid or spheric in horticulture), almost completely withdrawing into substrate when desiccated, (2.4–)5–9 × 1.5–4.7 cm, above-ground portion 1–6.5(–9); tubercles 5–9(–12) × 4–6(–7) mm; areolar glands absent; parenchyma not mucilaginous; druses present, largest druses lenticular, 0.3–0.5 mm diam.; pith 1/5–1/3 of lesser stem diam.; medullary vascular system not recorded. <b>Spines</b> (12–)15–20(–25) per areole, white with brown tips (quickly weathering to gray) or the adaxial spines per areole dark gray-brown throughout; all radial spines or 1–3 adaxial spines sometimes interpreted as central, laterally compressed at base, 6–13 × (0.1–)0.2–0.3 mm; subcentral spines 0(–3) per areole; central spines 0(–3) per areole, appressed, straight, ± equal, 9.5–13(–15) × 0.2–0.3 mm. <b>Flowers</b> nearly apical, 18–25 × 20–34 mm; outer tepals fringed; inner tepals 22–27 per flower, bright rose-pink or magenta, proximally paler, 10–17 × 2–4 mm; outer filaments colorless or white to rose; anthers orange-yellow; stigma lobes (4–)5–6(–7), white, cream, or pale pink, 1–3 mm. <b>Fruits</b> green, spheric or obovoid, (3.5–) 5–8(–10) × 3–6 mm, quickly drying; floral remnant usually persistent. <b>Seeds</b> dark brown, spheric, 0.9–1.1(–1.2) mm, pitted. <b>2n</b> = 22.</span><!--

--><p>Coryphantha hesteri resembles C. vivipara but is much smaller in all parts. Coryphantha hesteri is characteristic of the dwarf cacti on novaculite outcrops but is not limited to that substrate.</p>
