Cool, shady stream-banks and wet areas. Associated with Hackelia micrantha, Castilleja miniata, and Salix spp. The material I collected fits the description of M. ciliata regarding flowers, specifically anther lengths and ratio of corolla tube to limb length; but it has short petiolate upper leaves as in M. paniculata (Ait) G. Don. Voucher: Whitehead, G.S. 1983. M.S., Idaho State U. Flora of the Island Park Geothermal Study Area. Duplicates to: IDS, RM. Phenology: Flowers.
