Blum, A.G. (2015) Eriophyllum wallacei (Gray) Gray. (Asteraceae) Woolly Daisy. Flowers photographed in ultraviolet, visible and infrared light. http://www.ultraviol...i-woolly-daisy/

 

Synonyms:

  • Eriophyllum wallacei var. calvescens S.F. Blake
  • Wallace's Woolly Daisy
  • Woolly Sunflower

Comment:

The little Woolly Daisy, affectionately known as one of the 'Belly Flowers', is very UV-dark against the UV-bright desert floor. In infrared light it all but disappears.
