Trichoptilium is a monotypic genus in the daisy family containing the single species Trichoptilium incisum, which is known by the common names yellowdome[1] and yellowhead.
Description
[edit | edit source]Trichoptilium incisum grows up to 20 centimetres (8 in) tall.[2] It sends up stems from a basal rosette of sharply toothed leaves which are up to 5 cm (2 in) long[2] and covered in curly hairs and oil glands. Atop each stem is a rounded bright yellow flower head about 1.5 cm (1⁄2 in) wide[2] with only disc florets. Each head is a hemispherical button about 1 cm in diameter. The fruit is bristly with pappus.
Distribution and habitat
[edit | edit source]The plant is native to the Mojave and Sonoran Desert regions of the United States and Mexico.
It appears in late winter, and depending on rain, sometimes in autumn.[2]
