Blum, A.G. (2013) Encelia farinosa A. Gray ex Torrey (Asteraceae) Brittlebush. Flowers photographed in ultraviolet, visible and infrared light.http://www.ultravioletphotography.com/content/index.php?/topic/133-encelia-farinosa-brittlebush/

 

Synonyms:

  • Incienso
  • White Brittlebush

Comment: The ubiquitous E. farinosa with its silvery green leaves and bright yellow flowers provides a pretty sight along the roads and highways in desert areas of California and Arizona. Its resins were used for glue and incense by Native Americans. It has a UV-dark central disc with brighter, veined rays.
