|discussion=<p>Typically, sepals of <i>Prunus gracilis</i> are eglandular; in some specimens, glands occur along the margins. Similar glands are sometimes found on the tips of teeth along the leaf margins. The teeth are always sharp-pointed rather than blunt or rounded as they are in those plums whose leaves consistently have glandular teeth. Presence of glands on the sepals is not correlated with glands on leaf marginal teeth. <i>Prunus gracilis</i>, native to the southern Great Plains, is very similar to <i>P. maritima</i>, a plum of the eastern seaboard over 1600 km away.</p>
