|discussion=<p><i>Amelanchier nitens</i> is rarely found outside of pinyon pine-juniper community types; it often grows adjacent to seasonal streams and washes. The species is distinguished by its lustrous and coriaceous leaves (particularly in lower elevation populations), moderately hairy twigs, usually salmon-colored bark on older branches and trunks, relatively short inflorescences, and (typically) three styles. Petioles on many live specimens are a bright, lustrous red, a character state that is less noticeable on herbarium specimens. Stems are usually highly contorted, with relatively short internodes, abundant short shoots, and, often, divaricately branching ultimate branches. Seeds of <i>A. nitens</i> are much larger than congenerics (a sample of 25 averaged 7.3 times heavier than 25 seeds from an average eastern North American <i>Amelanchier</i>).</p><!--
--><p>The authors have observed incomplete herbarium specimens conforming to <i>Amelanchier nitens</i> (1923) morphology from Colorado, New Mexico, and Utah, including the type specimen of A. rubescens Greene (1900), which may prove to be the correct name for this species.</p>
