Oxalis caerulea (Blue Woodsorrel)
This species is (supposedly) distinguished from the more common Oxalis alpina and O. drummondii by having extended flanges at the petiole bases and two or more oxalate deposits at the distal end of each leaflet lobe.
Oxalis pilosa
This species is extensively branched above ground with small leaves and flowers. Variety pilosa differs by its uneven calyx pubescence and acute calyx lobes.
