Name derivation:
Cuphonotus from the Greek 'kyphos' meaning bent, humped, curved and 'notos' meaning the back; referring to the pod-valves being rounded on the back. Andraeanus named after Hans Andrae (1883-1890), who collected plants from around Pulpulla and Cobar in New South Wales.

Seed collecting:
Collect maturing pods, those turning reddish brown with orange seeds inside. Be gentle with the pods as they split open easily. Whole plant can also be collected.
Seed cleaning:
Place the pods in a tray and cover with paper to prevent seeds from popping out and leave to dry for a week. Then rub the dried pods 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.
Seed viability:
From one collection, the seed viability was high, at 100%.
Seed germination:
This species has physiological dormancy that need to be overcome for the seed to germinate.
