Erigeron piscaticus is a rare species of flowering plant in the aster family known by the common name Fish Creek fleabane.[2] It is endemic to Arizona in the United States, where it is known from three locations in Maricopa and Graham Counties.[1][3]
Erigeron piscaticus is an annual herb producing hairy, glandular stems up to 40 centimeters (16 inches) tall from a taproot. The oval leaves are 1 or 2 centimeters (0.4-0.8 inches) long and mostly smooth-edged. The flower heads are produced 1-4 per stem, each lined with hairy, glandular phyllaries. The heads contain 45–58 white ray florets each about 3 millimeters (0.12 inches) long.[2][4]
This plant grows on river terraces and washes. The "Fish Creek" part of the common name refers to Fish Creek Canyon in Maricopa County, where the type specimen was collected.[1][2][4]
