Description

Plagiobothrys arizonicus is an annual herb with a spreading or erect stem 10 to 40 centimeters in length. The leaves are located in a basal rosette about the stem, with smaller ones along the length of the stem. The plant is coated in long, rough, sharp hairs. The herbage leaks a staining purple juice when crushed.[1]

The inflorescence is a series of regular bracts and tiny flowers, each five-lobed white corolla less than 3 millimeters wide. The paired nutlets are arch-shaped and not prickly.
