This species, Pathenium integrifolium WILD QUININE, is so named because it is said to have chemicals that reduce a fever. I'm not sure if the flowers or leaves are made into a tea, or as part of a soup. At any rate, the 'flower' is composed of many disk flowers, the big round parts, and five ray flowers, the 'petals' of the flower. The petals are quite small and it's hard to see them in the photo at left. I hope to use this species in my next book, Elusive Splendor.
