--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>erect, oblate to spheric (to short cylindric), usually 10–20(–45) × 10–20(–35) cm; ribs 13–21[–34], shallowly notched immediately above each areole. <b>Spines</b> 10–19 per areole, central spines and larger radial spines pink or yellowish, smallest spines per areole slender, sometimes bristlelike, less than 1 mm diam. (rarely absent); central spines 4 per areole, straight or slightly curved, annulate, thin and flattened, narrowly elliptic in cross section, principal central spine 30–50 × 2–3(–5) mm. <b>Flowers</b> 2.5–5 × 3–6 cm, color similar inside and out; inner tepals greenish yellow, sometimes with reddish brown midstripes; stigma lobes yellow. <b>Fruits</b> ± readily dehiscent through basal pore, bright yellow (very rarely reddish), 20–35 × 15–25 mm, leathery or fleshy, locule dry, hollow except for seeds. <b>Seeds</b> 1.5–1.7 mm, pitted. <b>2n</b> = 22.</span><!--

|discussion=<p>In California, <i>Ferocactus viridescens</i> and <i>F. cylindraceus</i> are allopatric. In the absence of geographic data, the largest plants of <i>F. viridescens</i> might not always be distinguishable from straight-spined mature plants of <i>F. cylindraceus</i>. Immature plants of <i>F. cylindraceus</i> have mostly or entirely hooked spines but gradually switch to producing straighter spines in old age. In Baja California, the taxonomic distinctions between the two species are muddled.</p>
