--><span class="statement" id="st-undefined" data-properties=""><b>Shrubs </b>or trees, usually suckering, 10–80 dm, thorny. <b>Twigs</b> with axillary end buds, glabrous. <b>Leaves</b> deciduous; petiole 7–21 mm, glabrous or sparsely hairy on adaxial surface, glandular distally, glands 1–4; blade lanceolate, oblong-lanceolate, or elliptic to narrowly elliptic, usually folded along midribs, 4–11 × 1.5–5 cm, base obtuse to rounded, margins singly to doubly crenate-serrulate, teeth blunt, glandular, glands inconspicuous, blackish, apex usually acuminate, sometimes acute, abaxial surface glabrous or ± hairy along midribs and veins, adaxial usually glabrous, rarely midribs hairy. <b>Inflorescences</b> 2–4-flowered, umbellate fascicles. <b>Pedicels</b> 3–15 mm, glabrous. <b>Flowers</b> blooming before or at leaf emergence; hypanthium campanulate, 2–3 mm, usually glabrous, rarely glabrate, externally; sepals broadly spreading to reflexed, oblong-ovate, 1.5–2.5 mm, margins glandular-toothed, abaxial surface glabrous or sparsely hairy, adaxial densely hairy at bases; petals white, obovate, 4–7 mm; ovaries glabrous. <b>Drupes</b> usually red, sometimes yellowish orange, with white dots, not or only slightly glaucous, globose, 12–25 mm, glabrous; mesocarps fleshy; stones ovoid to subglobose, ± flattened.</span><!--

|discussion=<p><i>Prunus</i> munsoniana is here placed in synonymy with <i>P. rivularis</i>, greatly expanding the range of the latter compared to its traditional treatment. Descriptions of P. munsoniana and <i>P. rivularis</i> differ mostly in size of the plants, leaves, and floral structures. As suggested by G. M. Diggs et al. (1999), P. munsoniana is simply a larger version of <i>P. rivularis</i>.</p><!--
--><p>Evidence from analysis of DNA sequences of two nuclear genes in native plums (J. R. Rohrer et al. 2008) indicates that <i>Prunus rivularis</i> may be an allopolyploid. Three plants sequenced from Texas contained alleles seemingly derived from <i>P. angustifolia</i> on the one hand and <i>P. hortulana</i> (or <i>P. murrayana</i>) on the other. Further, two individuals determined as P. munsoniana, one each from Pennsylvania and Texas, had sequences very similar to those of <i>P. rivularis</i>.</p><!--
--><p>Other specimens in herbaria labeled as <i>Prunus</i> munsoniana include hybrids between <i>P. americana</i> and <i>P. angustifolia</i>, as well as individuals of <i>P. hortulana</i> that bloom before the leaves emerge or that sucker freely.</p>
