Impatiens ecalcarata

Impatiens ecornuta, the spurless touch-me-not or western touch-me-not, is an annual flowering plant native to the northwestern United States and British Columbia in Canada.[1][2]

The name of the species was changed in 2012 as Impatiens ecalcarata was found to be nomen illegitimum.[3]
