Morphology General Habit
Cushion-forming perennial succulent aromatic herb to 0.15 m tall with stems arising from a small fibrous root system
Morphology Stem
Stems procumbent to ascending, quadrangular, rooting at nodes, much branched or not, pubescent with glandular and eglandular hairs and with colourless and yellowish sessile glands
Morphology Leaves
Leaves spreading to ascending, succulent, subsessile or petiolate; blades elliptic or broadly so, 5–25 × 4–10 mm, weakly and distantly dentate, apex obtuse, base cuneate, sparsely pubescent, with yellowish sessile glands; petiole 1.5–3 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence terminal, lax or condensed, with 6–12-flowered verticils 2–10 mm apart, with bracts subtending 3–6-flowered sessile or shortly cincinnate cymes; bracts leaf-like but smaller; pedicels 4–7 mm long
Morphology Reproductive morphology Flowers Calyx
Calyx 2 mm long, pubescent, with yellowish and colourless sessile glands; fruiting calyx 3–4 mm long, shortly tubular, curved slightly upwards with pedicel attached excentrically behind the posterior lip; throat truncate; posterior lip elliptic, curving upwards, shortly decurrent; anterior lip with lobes lanceolate, median narrower and exceeding lateral; sinus between anterior lobes slightly deeper than that between the lateral lobes and anterior lobes
Morphology Reproductive morphology Flowers Corolla
Corolla bluish, almost glabrous but with scattered hairs and yellowish glands, 5–6 mm long, soon falling; tube 2.5–3 mm long, sigmoid; posterior lip shorter than anterior; anterior lip 2.5–3 mm long, horizontal, weakly cucullate, enclosing stamens
Morphology Reproductive morphology Flowers Androecium Stamens
Staminal filaments free
Morphology Reproductive morphology Fruits
Nutlets brown shiny with reddish gland dots, broadly obovoid, flattened, 1 mm long, producing mucilage speckled on outer surface.
Dry coastal forest and bushland; 40–550 m
Possibly Endangered; (EOO 144.046 km2, 4 collections from 2 localities; AOO 515.64 km2 with cell width 16.06 km, number of cells 2, 2 subpopulations based on adjacent cells; 2 subpopulations based on Rapoport distance; EOO area suggests species may be endangered)
Close to P. prostratus but differing in lacking red gland dots (except disk), the sessile glands being yellowish, more deeply dentate leaves and larger flowers. P. auriglandulosus smells of Eucalyptus.
