Synonyms:

• Thalictrum amissum
  
• Thalictrum fendleri var. platycarpum
  
• Thalictrum fendleri var. wrightii
  

Comment: The graceful Fendler's Meadow-rue is quite common in the Western two-thirds of New Mexico. Its flowers are unisexual with the staminate and pistillate flowers occuring on separate plants (dioecious). The example shown below from my garden is a male plant with reddish filaments on the dangling male flowers.

The male plant is UV-absorbing and other than some false blue filaments is otherwise unremarkable.

Andrea, I think you mixed up the UV+Blue+Green and the infrared.
