Landerolaria humilis
species of flowering plant
Landerolaria humilis (synonym Olearia humilis) is a species of flowering plant in the family Asteraceae and is endemic to the south-west of Western Australia. It is an erect, spindly shrub with narrowly egg-shaped or linear leaves, and purple and yellow, daisy-like inflorescences.
Description
Landerolaria humilis is an erect, spindly shrub that typically grows to a height of 0.4–1 m (1 ft 4 in – 3 ft 3 in). Its stems and leaves are covered with scattered thread-like and glandular hairs. The leaves are arranged alternately along the branchlets, narrowly egg-shaped with the narrower end towards the base or linear and often curved, 20–30 mm (0.79–1.18 in) long, 1–3 mm (0.039–0.118 in) wide and sessile. The heads or daisy-like "flowers" are arranged singly on the ends of branchlets and are 15–30 mm (0.59–1.18 in) in diameter on a peduncle up to 40 mm (1.6 in) long. Each head has twenty to thirty purple or bluish-purple ray florets, the ligule 9.6–14.2 mm (0.38–0.56 in) long, surrounding a similar number of yellow disc florets. Flowering occurs from July to November and the fruit is a flattened, light brown achene, the pappus with 21 to 33 bristles.
Taxonomy
The species was first formally described as Olearia humilis by Nicholas Sèan Lander in 1989 in the journal Nuytsia from specimens collected by Philip Sydney Short, near the Sandstone-Paynes Find road in 1986. The specific epithet (humilis) means "low" or "small", referring to the stature of this species.
The public source identifies “Landerolaria humilis” as species of flowering plant. This brief keeps that definition visible, then builds a research path around Landerolaria, humilis and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Landerolaria humilis”, the useful work is to connect “species of flowering 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 2, 2026. The linked authority identifier is Q138536705. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1989 and 1986.
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
