Pacific Waterleaf (Hydrophyllum tenuipes)

Cascade Head Nature Preserve, OR, 4/2014.

Like other members of the waterleaf family, the stamens of the flowers extend beyond the corolla and the leaves are large and numerous, allowing them to collect moisture.  This species is also known as “Slender-stem Waterleaf.”   The Greek hydrophyllum is a direct translation of the common name.

Compare to the bluish  Ball-head Waterleaf.
