Common name; Western Meadowrue

USDA lists two varieties:
var. macounii: WA, BC
var. occidentale: western NA

from eFlora.org
Thalictrum occidentale is similar to T . confine and T . venulosum ; thorough field studies are needed to determine whether or not they should be maintained as separate species.
Thalictrum occidentale can usually be distinguished by its reflexed achenes.

Plants of northern British Columbia, sometimes called Thalictrum occidentale var. breitungii
(B. Boivin) Brayshaw, appear to be intermediate between T . occidentale and T . venulosum (T. C. Brayshaw, pers. comm.);
achenes are ascending, ± compressed, and beaks rather short (2-4 mm) (T. C. Brayshaw 1989).

Note female and male (hanging stamens) flowers. Flower stem branches with mostly heavily veined stem leaves that are toothed/lobed on the leaf ends. Grows in subalpine meadows.

Nearly impossible to photograph as it moves in the slightest breeze.
