Arnoglossum atriplicifolium
species of plant
Arnoglossum atriplicifolium, the pale Indian plantain, is a perennial herbaceous wildflower in the sunflower family (Asteraceae). native to the central and eastern United States. It can reach heights of up to 3 metres (10 ft), with dramatic clusters of white flowers at the top of a central, unbranching stalk.
Description
Arnoglossum atriplicifolium is a large perennial plant with an unbranched stalk up to 2 metres (5 ft) tall, sometimes much taller, rising from a basal rosette up to 0.3 metres (1 ft) wide. The stalk is pale green to pale purple and has alternate leaves measuring up to 20 centimetres (8 in) long and 20 centimetres (8 in) across, becoming smaller as they ascend the stalk. The stems and lower surface of the leaves have a grayish white color, which is the source of the "pale" in the common name and is a distinguishing feature when differentiating it from other species in the Arnoglossum genus.
At the top of the central stalk is a flat-topped corymb, or cluster, of 4 to 15 flower heads. Flower heads are white, sometimes with a bit of green or purple, with disc florets but no ray florets. The plant spreads by means of underground rhizomes.
Distribution and habitat
It is widely distributed through the central and eastern states of the United States, from the Atlantic Coast westward to as far as Kansas, but it is listed as endangered in the state of New Jersey.

Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 16, 2025. The linked authority identifier is Q4794897. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
