Trimeris anceps (synonym Lobelia anceps), commonly known as angled lobelia,[2] is a small herbaceous plant in the family Campanulaceae. It is a small, perennial herb with blue to purple flowers. It grows in several states of Australia, New Zealand, the Tubuai Islands, Chile, southern Africa, and Madagascar.[1]
Description
Lobelia anceps is a prostrate to ascending, glabrous, perennial herb typically growing to a height of 50 cm (20 in), occasionally branches rooting at nodes. The leaves are variable, angled or more or less winged, linear-elliptic, oblong to oval spoon-shaped, 10–85 mm (0.39–3.35 in) long, 1.5–20 mm (0.059–0.787 in) wide, toothed or smooth, and often red to purplish at the base and the petiole 0–20 mm (0.00–0.79 in) long. The blue, purple or occasionally white flowers are borne singly in leaf axils on a pedicel 2–12 mm (0.079–0.472 in) long. The corolla usually 5–15 mm (0.20–0.59 in) long, the two upper petals narrower than the three lower petals. Flowering occurs mostly in summer and autumn and the fruit is a conical shaped capsule covered in soft, upright hairs or smooth, 5–15 mm (0.20–0.59 in) long and 1.5–3 mm (0.059–0.118 in) in diameter.[2][3][4]
Taxonomy and naming
The species was first formally described as Lobelia anceps by Carl Linnaeus the Younger in 1782, and the description was published in Supplementum Plantarum.[5][6] The specific epithet (anceps) means "two-sided, double, flattened", referring to the leaves.[7] In 2024 Eric B. Knox placed the species in genus Trimeris as T. anceps.[1]
Distribution and habitat
In Australia Angled lobelia is found along the banks of pools, creeks and rivers along coastal areas in New South Wales, Victoria, Queensland and South Australia. In Western Australia it grows between the Mid West and Goldfields-Esperance regions of Western Australia in sandy-peat-clay soils over granite or limestone.[3][8]
