Source-derived summary

Rudbeckia laciniata, the cutleaf coneflower, is a species of flowering plant in the family Asteraceae. Other common names include cutleaf, goldenglow, green-headed coneflower, tall coneflower, sochan and thimbleweed. It is native to North American floodplains, stream banks, and moist forests. Although toxic to animals, the leaves have culinary uses.

Description

It is a robust herbaceous perennial plant growing up to 2 metres (6+1⁄2 feet) tall. Long rhizomes are formed as persistence organs with fibrous roots. The stem is bare. The alternate leaves are usually divided into a petiole and a leaf blade. They are up to 20 cm (7+3⁄4 in) long, broadly ovate, somewhat glaucous, and often deeply dissected, with smooth to roughly serrated margins. The smooth or hairy leaf blade is simple or one to two-pinnate.

Editorial summary

The public source identifies “Rudbeckia laciniata” as species of plant. This brief keeps that definition visible, then builds a research path around Rudbeckia, laciniata and species.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 127-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Rudbeckia, laciniata and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Rudbeckia laciniata”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Oct 3, 2025. The linked authority identifier is Q1194614. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
