Erigeron piscaticus
species of plant
Erigeron piscaticus is a rare species of flowering plant in the family Asteraceae known by the common name Fish Creek fleabane. It is endemic to Arizona in the United States, where it is known from three locations in Maricopa and Graham Counties.
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.
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.
This brief starts where responsible research should: with the source description of “Erigeron piscaticus” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Feb 11, 2026. The linked authority identifier is Q5388422. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
