--><span class="statement" id="st-undefined" data-properties=""><b>Shrubs,</b> suckering, 10–40 dm, thorny. <b>Twigs</b> with axillary end buds, hairy. <b>Leaves</b> deciduous; petiole 4–7 mm, hairy, eglandular; blade elliptic to obovate, 1.5–4 × 1–2.2 cm, base obtuse to rounded, margins crenulate-serrulate, teeth blunt, often glandular, apex acute to obtuse, abaxial surface hairy (especially along midribs and veins), adaxial glabrate. <b>Inflorescences</b> usually solitary flowers, sometimes 2-flowered fascicles. <b>Pedicels</b> 0.5–5(–8) mm, usually glabrous, rarely hairy. <b>Flowers</b> blooming before leaf emergence; hypanthium cupulate, 1.5–2.5 mm, glabrous externally; sepals spreading, oblong, 1.5–2.5 mm, margins glandular-toothed, surfaces glabrous or adaxially hairy at bases; petals white, elliptic, 4–8 mm; ovaries glabrous. <b>Drupes</b> bluish black, globose, 10–15 mm, glabrous; mesocarps fleshy; stones subglobose, ± flattened. <b>2n</b> = 32.</span><!--

|discussion=<p>As past flora writers (C. L. Hitchcock et al. 1955–1969; E. G. Voss 1972–1996) have noted, the distinctions between <i>Prunus spinosa</i> and <i>P. domestica</i> are not clear. Some researchers consider the hexaploid <i>P. domestica</i> to have been derived from the tetraploid <i>P. spinosa</i>, often in a scenario involving hybridization with <i>P. cerasifera</i>. It should not be surprising that some of the characters used in keys to separate these three taxa (spininess, indument, leaf size, pedicel length, numbers of flowers per bud) are subject to variation within each species and overlap among the species.</p>
