|discussion=<p><i>Micranthes idahoensis</i> appears to hybridize with <i>M. occidentalis</i> where their ranges overlap. Intermediates are abundant in some populations along the Idaho-Montana border and in Montana. This phenomenon may explain the range of filament shapes found in <i>M. occidentalis</i>, from flattened to sightly club-shaped. The issue of the status of <i>M. idahoensis</i> with respect to <i>M. marshallii</i> (D. L. Krause and K. I. Beamish 1972) is best deferred until a thorough study of the whole complex over its entire range is done.</p>
