Synonyms:

  • Eunanus bigelovii A.Gray
  • Mimulus bigelovii (A.Gray) A.Gray
  • Mimulus spissus A.L.Grant

Comment:

This bright magenta, desert-dwelling Bigelow's Monkeyflower, native to the US West, has a speckled, vivid yellow throat which presents a much more subdued appearance in UV where the throat becomes UV-black and the petals moderately UV-absorbing. However, against the UV-bright desert floor, the cluster of UV-dark Monkeyflowers stands out.

So pretty, Andrea. I love the glitter of the conical cells(?) in the 3rd and 4th pics from the top.
