species of plant
Enceliopsis nudicaulis is a North American species of flowering plants in the family Asteraceae known by the common name nakedstem sunray, or naked-stemmed daisy.
Description
E. nudicaulis is a perennial herb growing up to 45 centimeters (18 inches) tall from a woody caudex fringed with gray-green hairy leaves. The leaves are oval and up to 6.5 cm (2+1⁄2 in) long and wide.
Blooming from May to August, the inflorescence is a solitary flower head atop a tall, erect peduncle. The flower head is 7.5–10 cm (3–4 in); it has a base made up of three layers of densely woolly, pointed phyllaries. It has a fringe of approximately 21 yellow ray florets each 2 to 4 cm (3⁄4 to 1+1⁄2 in) long. The fruit is a hairy achene about 1 cm in length.
Varieties
There are two recognized varieties of this species:
Enceliopsis nudicaulis var. corrugata, the Ash Meadows sunray – the rarer variety, which is probably endemic to Nevada in the vicinity of Ash Meadows in the Amargosa Desert. It is federally listed as threatened and is listed as a critically endangered and fully protected species by the State of Nevada.
Begin with the source’s own compact description: “Enceliopsis nudicaulis” is species of plant. The dossier treats that line as a proposition to test through Enceliopsis, nudicaulis 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.
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 Oct 22, 2025. The linked authority identifier is Q3053763. 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.
