Lateral lobes linear-spathulate, upcurved, clasping column, sparsely hairy on inside of base. Mid-lobe narrowly elliptical. Lamina callus of 2 linear, convergent, pubescent keels. Central band of white hairs from apex of callus to apex of mid-lobe, occupying most of surface of mid-lobe. Flowering between December and February. Fruits are brown papery ellipsoid capsule. Seeds are very small enclosed in a long narrow mesh-like casing.

Seed collection and propagation

Collect seeds between February and March. Collect plump capsules as they start to dry and turn brown. Pods will split and release the seeds quickly however and will require monitoring. To increase the chances of collecting mature pods it is recommended that a small breathable bag (ie. Organza) to 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 liquid nitrogen.
