Syntrichopappus is a genus of flowering plants in the family Asteraceae, found in the Southwestern United States and northern Mexico, including Baja California. It is a member of the Heliantheae alliance of the Asteraceae.[1] There are two species.[2] Common names include xerasid[2] and Frémont's-gold.[3]
The name "Syntrichopappus" derives from a Greek name: "syn" = "joined together", "tricho" = "hair", of the "pappus", which means many bristles fused at the base (however some species have no pappus).[2][4][clarification needed] The common name "xerasid" derives from Greek, meaning "son of dryness".[2]
Leaves are simple, alternate, sometimes with the lowest ones opposite.[4]
Flower heads are solitary.[4] There is one yellow (or white with red veins) ray flower per phyllary, with 3-lobed ligules.[4] The yellow disk flowers are narrowly funnel shaped.[4]
The fruits have 0 to many pappus bristles, fused at the base.[4]
