Name derivation:
Cyphanthera from the Greek 'cyphos' meaning bent forwards and 'antheros' meaning an anther; referring to horseshoe-shaped anthers. Myosotidea means having resemblance to the genus Myosotis (forget-me-not).
Distribution:
Found on the Eyre Peninsular, Kangaroo Island and the Murray in South Australia, growing in mallee on sandy soil, usually in disturbed sites. Also found in Victoria.
Status:
Native. Common in South Australia. Common in the other states. More common after fire.
Plant description:
Rounded undershrub to 30 cm tall and 45 cm wide, with branches covered in hairs. Leaves oblong, elliptic or ovate, sessile or almost so, to 10 mm long and 4 mm wide, green, covered in hairs. Inflorescence solitary, or in 1–3 clusters with white with purple striated flowers. Flowers mainly in spring.
Fruit type:
Brown globose to broadly ovoid capsule to 4 mm long, containing numerous seeds.
Seed type:
Light brown oblong to bean-shaped seed to 3 mm long and 1 mm wide, with a mesh-like surface.
Embryo type:
Linear fully developed.
Seed collecting:
Collect capsules that are maturing, fat, turning a straw colour and contain hard brown seeds inside. Monitor the plants as the capsules will dry, split and disperse the seeds in a short space of time. Using of a small bag (ie. Organza bags) to enclose the developing capsules will help to increase the chances of collecting sufficient viable seeds. More common post fire. 
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand or with a rubber bung 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 average, at 75%.
Seed germination:
This species has physiological dormancy that need to be overcome for the seed to germinate (i.e a fire responsive species).
