|discussion=<p>Of the three subspecies of <i>Frangula purshiana</i>, <i></i>subsp.<i> ultramafica</i> is the most distinctive and might warrant species status. It appears to be restricted to the Feather River complex of serpentinized peridotite and associated mafic and ultramafic substrates near Bucks Lake in Plumas County. Its firm, bluish or greenish gray leaves are suggestive of evergreen <i>F. californica </i>subsp.<i> tomentella</i>, but they are broader and larger and bear only simple, erect hairs. The leaves are deciduous as in <i>F. rubra</i>, but the large, broad leaves and fruits with three stones are like those of <i>F. purshiana</i>.</p>
