Day 208: Tiny Anemone lyallii (Lyall's Anemone) is relatively uncommon in Mount Rainier National Park, and it is often overlooked because of its size, which this Penny Perspective clearly demonstrates. It can be distinguished from similar A. deltoides by the leaf arrangement (three "threes" in the case of A. lyallii and only one set of three in A. deltoides). A third species (Anemone oregana) is larger, although small specimens can be confused with A. lyallii. The distinction between the two is most easily made when the plants are in bloom. Oregon Anemone has 35 or more stamens, Lyall's less than 35. Lyall's may also be listed as Western Wood Anemone in some field guides.
