There were a few patches of Oxalis oregana or Redwood Sorrel along the path on the north side of Lake Crescent at 580'. It was too late for the flowers. This was the first time I'd seen Oxalis oregana this far east in Washington state; before I'd only seen it along the west coast.
Small yellow flowers, leaves similar to clover.

The Oxalidaceae, or wood sorrel family, are a small family of eight genera of herbaceous plants, shrubs and small trees, with the great majority of the 900 species in the genus Oxalis (wood sorrels). Members of this family typically have divided leaves, the leaflets showing "sleep movements", spreading open in light and closing in darkness.
