Name derivation:
Gastrodia from the Greek 'gastrodes' meaning pot-bellied; referring to the swollen, sometimes bulbous flower. Sesamoides meaning sesame like; referring to the tubular corolla, which is gibbous at the base as in the flowers of Sesamum indicum - the sesame.
Distribution:
Found in the southern Mount Lofty Ranges, Kangraoo Island and the lower South-east in South Australia, growing in areas of high rainfall in wet sclerophyll forests, dry sclerophyll forests, woodlands and riparian areas. Also found in Queensland, New South Wales, Victoria and Tasmania.
Status:
Native. Rare in South Australia. Common in the othner states.
Plant description:
Grows to 50 cm tall with up to 20 small flowers.  These epiparasitic herb are leafless but have scale like bracts along the brown stem. Flowers are bell-shaped, cinnamon-brown with white tips to 15 mm long. It differs from Gastrodia procera by having a more slender habit, less crowded flowers and a strongly deflexed stem tip. Flowering between October and January.
Fruit type:
Brown papery ellipsoid capsule.
Seed type:
Very small yellow ovoid seed with a translucent clear mesh-like covering.
Seed collecting:
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.
Seed cleaning:
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.
