Perennial herb growing from an underground tuber with a single erect, hairy, lance-shaped leaf to 80 mm long and 11 mm wide. Inflorescence solitary on a long stalk to 30 cm high, with a white to pinkish flower with darker stripes. Dorsal sepal lance-shaped near the base, wide and narrowing to a thread-like tip covered with many black glands. Lateral sepals are linear to lance-shaped and narrowing to a tip similar to that on the dorsal sepal. Petals are similar to the lateral sepals but slightly shorter and narrower. Labellum is whitish or pinkish, sometimes with red markings with erect lateral lobes, with seven to nine calli on the sides of the lobes and many short, white-tipped calli along the centre of the labellum. Flowering between August and September and is known to flower profusely after fire. Fruits are brown hairy, papery ellipsoid capsule containing numerous tiny seeds.
Seed collection and propagation
Collect seeds between October and November. Collect fat capsules as they start to dry and turn brown. Pods will split and release the seeds quickly and will require monitoring. To increase the chances of collecting mature pods, it is recommended that a small breathable bag (ie. Organza bags) be used to enclose the developing capsules. Place the capsules in a container that will hold fine seeds and leave to dry for a few weeks or until the capsule split. Then carefully hold the capsule and tap it gently to release the seeds. 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, refrigerator or in liquid nitrogen.
