Trichoptilium incisum sends up stems from a basal rosette of sharply-toothed leaves which are covered in curly hairs and oil glands. Atop each stem is a small rounded bright yellow flower head with only disc florets. Each head is a hemispherical button about a centimeter in diameter. The fruit is bristly with pappus.
