RavenOenothera claviformis Torrey & FrémontComment:Chylismia claviformis is a complex species with many subspecies found across the western US and northern Mexico. It has an interesting UV signature with UV-neutral petals and filaments, a UV-bright curly ring at the base of the corolla and a UV-dark area inside that ring. The base of the stigma has some UV-bright hairs. Reference:1. Jepson eFlora (2013) C. claviformis (Torr. & Frém.) A.Heller.
