Small terrestrial herbnnial. Leaves few, rosetted and on stolons, narrow-lanceolate to narrow-linear, to 45 mm long and 1.6 mm wide. Inflorescence erect, 1 to several, erect, 35 cm long, with 1–10 dark violet flowers, upper lip obovate, lower lip much larger, hatchet-shaped to reniform, with 4–11 yellow, slightly raised radiating ridges. Flowering September to March. Fruits are brown globular capsule to 5 mm diameter. Seeds are tiny dark brown ovoid seed to 0.8 mm long and 0.3 mm wide, with a thin mesh-like covering.

Seed collection and propagation

Collect seeds between October and May. Collect mature capsules, those turning a brown colour, fat and containing brown seeds. Can collect individual capsules or break off the whole stem. Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 95%.
