Corydalis curvisiliqua
(Curvepod Fumewort)
Family: Fumariaceae (Fumitory)
  
The yellow flowers of Corydalis curvisiliqua almost look like flowers of the Pea Family. Racemes of flowers are held above the leaves. Seed pods are held erect on the stalk. Plants grow to a height of 5 to 16 inches.

Compare to Corydalis aurea (Golden Smoke). Flowers of Golden Smoke are lower on the plant, at about the same height as the leaves. Seed pods hang or spread. Some taxonomists consider Colorado's Corydalis curvisiliqua to be a subspecies of Corydalis aurea and name it Corydalis aurea ssp. occidentalis.
