Source-derived summary

Calectasia obtusa, commonly known as a blue tinsel lily or blunt-leaved tinsel lily is a plant in the family Dasypogonaceae growing as an erect, small shrub with stems to 50 cm. It is endemic to the south-west of Western Australia, widespread in most of its range but only known from nine populations.

Description

Calectasia obtusa is an undershrub with stilt roots 30–55 mm long but no rhizome. It grows to a height of about 50 cm with several short side branches. Each leaf blade is glabrous except at the margins, 4.5–8.5 x 0.5–0.9 mm, often pressed against the stem, the ends usually blunt and only rarely tapering to a short, sharp point. The base of the petals (strictly tepals) form a tube 7.7–8.8 mm long, while the outer part of the petals are wine red with blue margins fading to pale blue with age and spreading outwards to form a papery, star-like pattern. In the centre of the star are six yellow stamens forming a tube which does not change colour with age. The thin style extends beyond the stamens. It is similar to the other species of Calectasia and is distinguished from them mainly by the combination of the absence of a rhizome and the glabrousness and lack of a sharp point on the ends of the leaf blades. Flowers mostly appear from July to August.

Editorial summary

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

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 227-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 Calectasia, obtusa 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 “Calectasia obtusa”, 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 Nov 25, 2024. The linked authority identifier is Q15588483. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.

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.
