Description: Shrub 0.6–2(-3) m tall, glabrous, initially erect to spreading but longer branches frequently pendent, open and often sparsely branching from c. 10 cm above base.
Leaves usually not persisting more than 20 cm below apex, erect to spreading, sheathing at base; sheath pale brown c. 8 mm long and 12 mm wide, gradually narrowed into lamina, margin somewhat membranous; lamina coriaceous, dark to mid green, abaxially slightly paler, linear-triangular, (85-)140–200 mm long and 6–9 mm wide, flat to slightly concave; margin serrulate; tip acute and often brownish.
Inflorescence terminal, flowers maturing basipetally; each node with a caducous leaf-like bract, usually with 2 or 3 flowers per node basally and 1, or occasionally 2, flowers per node distally; flowers large for genus, deflexed to spreading, becoming erect after corolla has dropped, sometimes secund. Bracts brown, triangular, c. 50 mm long, 11 mm wide. Bracteoles similar to bracts but smaller, c. 8 mm long, 0.5 mm wide. Calyx rose-coloured (becoming scarious and reddish brown with margin paler in fruit), lobes triangular, (8-)9–10(-11) mm long, 2–2.5 mm wide, c. ½ corolla length; margin membranous, ciliolate especially in distal half; apex acute. Corolla dark pink becoming red with age, lobes white; tube cylindrical, (16-)18–22(-25) mm long, 3–3.5(-4) mm diam.; lobes spreading, ovate, 2.5–4 mm long, 1.5–3 mm wide, base obtuse to subcordate, apex obtuse, surface rugose-verrucate. Stamens with filaments inserted at base of corolla tube, 18–20 mm long; barely included in corolla throat. Pistil slightly longer than corolla tube; style filiform, (14-)17–19 mm long, minutely papillose distally; stigma indistinctly 5-lobed.
Fruit brown, shorter than calyx, style often persisting, seeds not observed.
Flowering: August–October (rarely to December).
Distribution and occurrence: This species is known only from the Lansdowne State Forest but may also occur in more northern areas of the Comboyne Plateau.
On rock outcrops in sheltered stream gullies and damp roadsides, usually in slightly more open areas in the forest.
NSW subdivisions: NC
A final determination to remove this species from the Vulnerable Species list under the NSW Biodiversity Conservation Act 2016 (NSW BCA 2016) was published on 19 Nov 2021, following the outcomes of targeted surveys conducted since the taxon was initially listed, and from a re-assessment of threats.
