Pales: “Pales are receptacular bracts which subtend all or some of the disc florets of capitulum.
They differ from phyllaries in that they subtend individual florets atop the receptacle vs. phyllaries which subtend the entire head of flowers.
They are present within some, but not all, Asteraceae genera, and are most common in the Heliantheae tribe.” — Weakley's Flora of the Southeastern United States
