Micranthes idahoensis (Piper) Brouillet & Gornall[FNA8, HC2]
Idaho saxifrage

Publication: J. Bot. Res. Inst. Texas. 1: 1020. 2007.

Origin: Native

selected vouchers: WTU

Notes: FNA8: "Micranthes idahoensis appears to hybridize with M. occidentalis 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 M. occidentalis, from flattened to sightly club-shaped. The issue of the status of M. idahoensis with respect to M. marshallii (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."
