Calectasia
genus of plants
Calectasia is a genus of about fifteen species of flowering plants in the family Dasypogonaceae and is endemic to south-western Australia. Plants is this genus are small, erect shrubs with branched stems covered by leaf sheaths. The flowers are star-shaped, lilac-blue to purple and arranged singly on the ends of short branchlets.
Description
Plants in the genus Calectasia are small, often rhizome-forming shrubs with erect, branched stems with sessile leaves arranged alternately along the stems, 5–17 mm (0.20–0.67 in) long and about 0.5 mm (0.020 in) wide, the base held closely against the stem and the tip pointed. The flowers are arranged singly on the ends of branchlets and are bisexual, the three sepals and three petals are similar to each other, and joined at the base forming a short tube but spreading, forming a star-like pattern with a metallic sheen. Six bright yellow or orange stamens form a tube in the centre of the flower with a thin style extending beyond the centre of the tube.
Taxonomy
The genus Calectasia was first formally described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen and the first species to be named was Calectasia cyanea. The name is derived from the Ancient Greek words kalos " beautiful" and ektasis "development", alluding to the blue spreading perianth-tubes.
Ludwig Preiss described C. grandiflora in 1846 and Otto Wilhelm Sonder added C. intermedia in 1856. In 2001, Barrett and Dixon reviewed the genus and added eight new species and in 2015 four more species were added making a total of 15.
Begin with the source’s own compact description: “Calectasia” is genus of plants. The dossier treats that line as a proposition to test through Calectasia, genus and plants, not as a finished interpretation.
Why this record matters
The phrase “genus of plants” 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 Jul 31, 2024. The linked authority identifier is Q3284380. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1810, 1846, 1856 and 2001.
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.
