|discussion=<p>Species ca. 500 (25 in the flora).</p><!--
--><p>The North American species of <i>Vaccinium</i> are distributed among ten sections. Some of these (e.g., Oxycoccus, Polycodium) have been treated as genera by recent authors, although only Oxycoccus has been recognized at genus rank widely among North American authors. Molecular data support the idea that <i>Vaccinium</i> is a natural genus, albeit large and diverse, provided that Oxycoccus is included.</p><!--
--><p>In eastern North America, the name huckleberry is applied to species of <i>Gaylussacia</i>, while in western North America some species of <i>Vaccinium</i> are called huckleberries. Most, if not all, species of <i>Vaccinium</i> are edible, finding wide acceptance as fresh fruits, and for pies, preserves, etc. Some have medicinal value, especially <i>V. macrocarpon</i> for urinary problems. Further uses and references are noted with the individual species.</p>
