--><span class="statement" id="st-undefined" data-properties=""><b>Shrubs </b>or small trees, to 6 m; branches dense, spreading at right angles, usually armed with stout, recurved spines 7–14 mm. <b>Stems</b> arching, velvety when young, glabrate later. <b>Leaf</b> blades broadly obovate or suborbiculate, 2–6 × 2–6 cm, base rounded or broadly cuneate, apex rounded, rarely subacute. <b>Inflorescences</b>: [staminate inflorescences subglobose, dense, 1–2 cm diam.]; pistillate inflorescences densely subglobose at anthesis, more open in age; branches divaricate or ascending; fruiting pedicel 0.5–2 cm. <b>Perianths</b>: [perianth of staminate flowers deep red, broadly campanulate, 2–3 mm, densely and shortly viscid-villous]; perianth of pistillate flowers greenish, often blushed with red, 2–2.5 mm, densely puberulent. <b>Fruits</b> clavate, 7–10 × 3–4 mm, densely puberulent between glandular ribs, glands extending entire length of fruits.</span><!--

|phenology=Flowering winter–early spring.
|habitat=Protected clefts on rhyolitic soils in arid scrub [tropical deciduous forests, thickets, along watercourses]
|elevation=0-1100 m
|distribution=Ariz.;nw Mexico.
|discussion=<p><i>Pisonia capitata</i> is represented in the flora by a single, possibly clonal, population of a few pistillate plants in south-central Arizona several hundred kilometers north of known populations in Sonora, perhaps originating from a freak event of bird dispersal. Plants are not known to have set seed.</p><!--
--><p>As noted above, pistillate plants of <i>Pisonia capitata</i> and <i>P. aculeata</i> exhibit no apparent differences, nor are there apparent vegetative differences between the species. That plants known in the flora truly represent <i>P. aculeata</i> is an assumption based on geography.</p>
