Grevillea refracta
species of plant
Grevillea refracta, commonly known as silver-leaf grevillea, is a species of plant in the protea family and is native to northern Australia. It is a tree or shrub usually with pinnatipartite leaves and red and yellow flowers arranged on a branched, downcurved raceme.
Description
Grevillea refracta is a tree or shrub that typically grows to a height of 2–6 m (6 ft 7 in – 19 ft 8 in) and 4 m (13 ft) wide. The leaves are 40–210 mm (1.6–8.3 in) long and pinnatipartite with up to 27 egg-shaped to elliptic or linear lobes 40–130 mm (1.6–5.1 in) long and 1–45 mm (0.039–1.772 in) wide. Sometimes there are elliptic to more or less linear leaves 70–190 mm (2.8–7.5 in) long and 2–31 mm (0.079–1.220 in) wide. The lower surface of the leaves is hairy. The flowers are arranged on one side of an often downcurved raceme with 2 to 6 branches 5–20 mm (0.20–0.79 in) long, the oldest flowers at the tips of the branches. The flowers are red and orange, yellow or pink, the pistil 15–22.5 mm (0.59–0.89 in) long. Flowering occurs from April to September and the fruit is a thick-walled, glabrous, elliptic to more or less spherical follicle 18–31 mm (0.71–1.22 in) long.
Taxonomy
Grevillea refracta was first formally described in 1810 by the botanist Robert Brown in Transactions of the Linnean Society of London.
Begin with the source’s own compact description: “Grevillea refracta” is species of plant. The dossier treats that line as a proposition to test through Grevillea, refracta 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 Dec 13, 2025. The linked authority identifier is Q15583006. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1810.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
