--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>straight, erect or nearly so (or leaning), cylindric, (20–)45–150(–300) × (20–)25–40(–50) cm; ribs (18–)21–31, shallowly notched immediately above each areole. <b>Spines</b> 12–32 per areole, central spines and larger radial spines whitish, yellow, pink, dull red, or brown; smallest spines per areole slender, sometimes bristlelike, less than 1 mm diam. (rarely absent); central spines 4 per areole, major rigid central spines surrounded by weaker subcentral spines; principal central spine moderately curved, sometimes twisted, usually not strongly hooked except on relatively young plants, annulate, adaxial surface usually flat or even concave, 36–140[–170] × 2–4.5 mm. <b>Flowers</b> maroon outside, yellow inside, 3–6 × 4–6 cm; inner tepals commonly yellow, (rarely with reddish midstripes, very rarely orange to red with a darker red midstripes); stigma lobes yellow (to red). <b>Fruits</b> ± readily dehiscent through basal pore, bright yellow (very rarely reddish), 30–40(–50) × 15–20 mm, leathery or fleshy, locule dry, hollow except for seeds. <b>Seeds</b> (1.5–)2–3 mm, pitted. <b>2n</b> = 22.</span><!--

|phenology=Flowering early spring–early summer (late summer–early fall).

|elevation=0-1500 m
|distribution=Ariz.;Calif.;Nev.;Utah;Mexico (Baja California;Sonora).
|discussion=<p>The name <i>Ferocactus</i> acanthodes has been widely applied to this species but was based on a small plant of unknown origin (and the original specimen lost), and is therefore ambiguous (N. P. Taylor 1979).</p><!--
--><p>The vernacular name “compass barrel” is sometimes misapplied to <i>Ferocactus cylindraceus</i>, which grows straight up in its old age, instead of leaning as would <i>F. wislizeni</i>.</p><!--
--><p>The varieties recognized by L. D. Benson (1982) are not consistently distinguishable.</p>
