About

Pyrrocoma liatriformis is a species of flowering plant in the family Asteraceae. Its common names include Palouse goldenweed and smallhead goldenweed. It is native to the northwestern United States, where it is endemic to the Palouse prairie, growing in grassland dominated by blue bunchgrass. It is a perennial herb growing from a taproot, producing one to three stems up to 70 centimeters (28 inches) in length. The stems are erect and hairy. Leaves near the base of the plant are larger and rounder than the leaves connected to the stem, which are lanceolate and hairy. Basal leaves measure 80–310 millimeters long and 9–30 millimeters wide, whereas cauline leaves measure 30–120 millimeters long and 5–20 millimeters wide. The inflorescence is four to five heads arranged in a raceme.
