Calothamnus borealis
species of plant
Calothamnus borealis is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small, erect shrub with crowded, cylindrical leaves and red flowers. It grows in sand surrounded by spinifex or heath. In 2014 Craven, Edwards and Cowley proposed that the species be renamed Melaleuca aquilonia.
Description
Calothamnus borealis is a low, spreading shrub with many stems, growing to a height of about 1.0 metre (3 ft) and with new growth covered with soft hairs. Its leaves are crowded, mostly 7–10 millimetres (0.3–0.4 in) long and 1.0–1.5 millimetres (0.04–0.06 in) wide, cylindrical in shape, tapering to a non-prickly point. They are covered with short hairs giving a greyish tinge.
The flowers are red and are arranged in small clusters containing 1 to 12 individual flowers, mostly hidden among the leaves. The petals are about 5 millimetres (0.2 in) long, pinkish to brownish in colour with a papery texture. The stamens are arranged in 5 claw-like bundles with 20 to 25 stamens per bundle.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Calothamnus borealis”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
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 May 21, 2026. The linked authority identifier is Q15396729. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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
