Ranunculus eschscholtzii Schltdl.
Eschscholtz's buttercup, Subalpine Buttercup
USDA Symbol: RAES
5 shiny, brilliant yellow petals are part of flowers that are sometimes so numerous as nearly to hide the foliage of this low plant.
Subalpine Buttercup has the largest flowers of North American species. There are many Buttercups, most with shiny yellow petals, and most difficult to identify. Yellow marsh Marigold (Caltha palustris var. palustris), from coastal bogs in Oregon to Alaska, resembles a Buttercup but lacks green sepals.
