FNA8: "Micranthes tischii is known only from the Olympic Peninsula and from inland, mountainous Vancouver Island, British Columbia (Ogilvie & Beguin 798911, V). Closely related to M. rufidula, M. tischii appears to be highly specialized for its habitat. The unusual persistent, green, not clawed (versus deciduous, white, clawed) petals readily distinguish the two species."
