It is widespread across much of Mexico and Central America, and has also been found in the southwestern United States (Arizona + New Mexico). Hieracium abscissum is an herb up to 75 cm (30 in) tall, with leaves on the stem and also in a rosette at the bottom.

Each head has 20-24 yellow ray flowers but no disc flowers.
