Source-derived summary

Philotheca wonganensis, commonly known as Wongan philotheca, is a species of flowering plant in the family Rutaceae and is endemic to the south-west of Western Australia. It is a shrub with thin, cylindrical leaves and white flowers with a pink central stripe, usually arranged singly in leaf axils.

Description

Philotheca wonganensis is a shrub that typically grows to a height of 1 m (3 ft 3 in) with corky branchlets. The leaves are thin, scattered, needle-shaped, 5–10 mm (0.20–0.39 in), sometimes glandular-warty, and channelled on the upper surface. The flowers are arranged singly in leaf axils on a thin, club-shaped pedicel about 5 mm (0.20 in) long. There are five broadly egg-shaped sepals about 1 mm (0.039 in) long and five white, oblong to elliptical petals about 5 mm (0.20 in) long with a pink central stripe. The ten stamens are free from each other and form a pyramid above the ovary. Flowering occurs from August to October and the fruit is about 3 mm (0.12 in) long with a short beak.

Taxonomy and naming

This philotheca was first formally described in 1982 by Paul Wilson who gave it the name Eriostemon wonganensis and published the description in the journal Nuytsia from specimens collected by Kevin Kenneally near Wongan Hills township in 1980. In 1998, Wilson changed the name to Philotheca wonganensis in the same journal.

Editorial summary

Begin with the source’s own compact description: “Philotheca wonganensis” is species of plant. The dossier treats that line as a proposition to test through Philotheca, wonganensis and species, not as a finished interpretation.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1982, 1980, 1998—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Philotheca, wonganensis and species is the immediate research focus.
Editorial analysis

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.

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 Jun 12, 2026. The linked authority identifier is Q18075539. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1982, 1980 and 1998.

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.
