Gutierrezia serotina is a North American species of flowering plant in the family Asteraceae known by the common name late snakeweed.
It is endemic to Arizona in the United States.[1] [2]
Gutierrezia serotina is a perennial herb or subshrub up to 30 cm (1 foot) in height. Leaves are very narrow, sometimes thread-like.
At the end of each branch there is an inflorescence of one or a few flower heads. The heads are larger than for most of the species in the genus. The head contains 8-17 disc florets with 4-9 yellow ray florets around the edge.[3]
