Philotheca sericea
species of plant
Philotheca sericea is a species of flowering plant in the family Rutaceae and is endemic to the south-west of Western Australia. It is an undershrub with small oval to elliptical leaves and white to pink flowers usually arranged singly at the end of branchlets.
Description
Philotheca sericea is a shrub that typically grows to a height of 1.5 m (4 ft 11 in) with moderately hairy branchlets. The leaves are fleshy, oval to elliptical, 1.5–3 mm (0.059–0.118 in), flat on the top and rounded on the lower side. The flowers are usually arranged singly at the end of branchlets, each flower on a pedicel about 0.5 mm (0.020 in) long. There are five triangular to round sepals about 2.5 mm (0.098 in) long and five white to pink, egg-shaped petals about 10 mm (0.39 in) long and densely covered with soft hairs. The ten stamens are joined at the base and hairy. Flowering occurs from July to September and the fruit is about 4 mm (0.16 in) long with a stout beak about 2 mm (0.079 in) long.
Taxonomy and naming
This philotheca was first formally described in 1970 by Paul Wilson who gave it the name Eriostemon sericeus and published the description in the journal Nuytsia from specimens collected by Nathaniel Speck near Kalli in 1964. In 1998, Wilson changed the name to Philotheca sericea in the same journal.
This brief starts where responsible research should: with the source description of “Philotheca sericea” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Apr 9, 2026. The linked authority identifier is Q18076907. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1970, 1964 and 1998.
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.
