Etymology
Pterostylis from the Greek ‘pteron’ meaning a wing and ‘stylis’ meaning a style or column; referring to the prominent wings found at the top of the column in all species.
Plant description
Fruits are brown papery ellipsoid capsule.
Seed collection and propagation
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 or in liquid nitrogen.
