Isocoma pluriflora
species of plant
Isocoma pluriflora, commonly called southern jimmyweed or southern goldenbush, is a North American species of flowering perennial herbs in the family Asteraceae. It grows in northern Mexico (Baja California Sur, Sonora, Chihuahua, Coahuila, Nuevo León) and in the southwestern and south-central United States (Arizona, New Mexico, Colorado and Texas).
Isocoma pluriflora grows 1–3.5 feet (0.30–1.07 m) tall. Leaves are narrow, up to 5 cm (2 inches) long. The plant produces numerous flower heads in a cluster at the top of the stem, each head with 8-21 yellow disc flowers but no ray flowers. The species is named "pluriflora", 'many flowered', for its up to 25-50 vertical and approximately parallel stalks, tipped with yellow golden flower heads.
Begin with the source’s own compact description: “Isocoma pluriflora” is species of plant. The dossier treats that line as a proposition to test through Isocoma, pluriflora and species, not as a finished interpretation.
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 5, 2024. The linked authority identifier is Q6085532. 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 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.
