• White Wakerobin
  

Pollinators: Bombis

 

Comment: Recent rain had splattered some dirt onto the white petals of this native Northeastern forest loving monocot. The obvious venation on the petals and leaves carries over in the UV to a dark-veined look. The strong presence of conical cells on the face of the flower gives rise to some iridescence which plays over the petals' moderately UV-dark appearance.
