--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>usually unbranched (often 2–3 branches in Chisos Moun-tains, Texas), spines obscuring stems. <b>Roots</b> diffuse (rarely short taproots). <b>Stems</b> spheric, becoming short cylindric in age, (3–)5–10.5(–16.6) × (2–)3–4.5(–6) cm; tubercles (4–)7–8(–12) × 3–5(–7) mm, moderately soft; areolar glands absent; parenchyma not mucilaginous; medullary vascular system absent. <b>Spines</b> (35–)40–55(–81) per areole, white, tips yellowish or reddish; radial spines 22–40+ per areole, 5–9 mm; central spines 8–10 per areole, spreading, straight, longest spines (4–)7–15 × 0.2–0.3(–0.40) mm. <b>Flowers</b> nearly apical, 12 × 6.5–13(–16) mm, sterile distal part of flower tube 0–2 mm, shorter than stamen-bearing part; outer tepals fringed (or entire); inner tepals pinkish to creamy white, with prominent, broad, pinkish salmon to light brown midstripes, 4.5–7(–9) mm; outer filaments pink; anthers yellow; stigma lobes green, ca. 1 mm. <b>Fruits</b> bright red, obovoid to clavate, (7–)13–24 × 3–6 mm, not very succulent; floral remnant strongly persistent. <b>Seeds</b> black, somewhat comma-shaped, 1–1.2 mm, pitted. <b>2n</b> = 22.</span><!--

|discussion=<p><i>Coryphantha chaffeyi</i> is nearly identical to <i>C. dasyacantha</i> and might yet prove to be conspecific. <i>Coryphantha chaffeyi</i> is distinguished only by the following characteristics: (1) flowers averaging smaller in all parts, as seen from living material; (2) spines whiter; (3) spines usually more numerous; and (4) populations confined to higher altitudes. Some populations (e.g., on limestone in the Del Norte Mountains and the Dead Horse Mountains, Texas) may be intermediate. However, in Chisos Mountains the two species seem to be sharply defined morphologically and widely separated ecologically.</p>
