--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>erect, branched or unbranched, not deep-seated in substrate. <b>Roots</b> diffuse. <b>Stems</b> unsegmented, gray-green to yellowish or bronze-tinted green, spheric to short cylindric, 5–10(–24) × (1.8–)2.5–6.5(–8) cm, usually white woolly at apex; tubercles prominent, not confluent into ribs, tightly packed in vertical, sprialing rows as if tuberculate ribs, compressed conic, 7–12 × 4–7 mm, 8–18 mm diam. at base; areoles adaxially elongated into long, narrow, conspicuous grooves extending into axils of tubercles, usually short woolly; areolar glands absent; cortex and pith not mucilaginous; specialized, yellow, sticky layer beneath old bark. <b>Spines</b> 9–17[–26] per areole, white, gray, brown, or black, acicular, straight; radial spines 9–15[–25] per areole, with bulbous bases, 6–17 mm; central spines [0–]6(–8) per areole, terete with bulbous bases. <b>Flowers</b> diurnal, at stem apex, at axillary end of areolar groove, showy, short funnelform, 2.5–3.2 × 3–5.5 cm; outer tepals whitish or magenta to purplish, to 25 × 10 mm, margins entire (sometimes irregularly, minutely denticulate); inner tepals bright rose-pink or magenta, 15–32 × 5–11 mm, margins entire; ovary smooth, spineless; stigma lobes 4–7, white to cream, 2–4 mm. <b>Fruits</b> dehiscent along vertical slits or indehiscent, green to white (slightly pinkish near base), becoming tan or greenish brown, spheric, 4–10 × 4–8 mm, dry and papery, smooth, spineless; pulp absent; floral remnant deciduous. <b>Seeds</b> black to gray, obovoid or pyriform, 1.1–1.6 × 0.8–1.2 mm, papillate; testa cells strongly convex. <b>x</b> = 11.</span><!--

|discussion=<p>Species 2 (1 in the flora).</p><!--
--><p><i>Neolloydia</i> is conspicuous, variable, and often confused with unrelated species, especially in <i>Coryphantha</i>. The papillate seeds are immediately diagnostic for distinguishing <i>Neolloydia</i> species from <i>Coryphantha</i> (seeds pitted, smooth, or ± reticulate), but they are seldom seen.</p><!--
--><p>Several other genera, especially <i>Thelocactus</i> and the Mexican Turbinicarpus, have been variously associated with <i>Neolloydia</i>. Alone among authors, L. D. Benson (1969, 1982) inexplicably submerged <i>Echinomastus</i> into <i>Neolloydia</i>. A long list of differences distinguish <i>Neolloydia</i> from <i>Echinomastus</i> (E. F. Anderson 1986). Chloroplast DNA evidence (C. A. Butterworth et al. 2002) indicated no close relationship between <i>Neolloydia</i> and the surveyed species of Turbinicarpus and <i>Thelocactus</i>; <i>Echinomastus</i> was not represented in the study.</p>
