Redwhisker clammyweed (Polanisia dodecandra), at Garden Wash.

This is my current nominee for plant-with-the-best-common-name. It is a cleome, with sticky-fuzzy hairs on stems and leaves that leave a gummy, foul-smelling sap on your hands when handled. The scientific name is useful and descriptive. The genus name

Polanisia

refers to the unequal lengths of the flowers’ stamens, while dodecandra indicates that each floret has twelve stamens.
