Name derivation:
Harmsiodoxa named after August Theodor Harms (1870-1942), a German taxonomist and botanist, with the Greek 'doxa' meaning praise. Blennodioides means resembling the genus Blennodia.
Found across the northern part of South Australia, growing in sandy soil. Also found in the Northern Territory, Queensland, New South Wales and Victoria.
Native. Common in South Australia. Common in the other states.
Plant description:
Erect, hairy annual herb to 30 cm tall. Basal leaves narrow-obovate, coarsely lobed to toothed with 1-3 pairs of triangular lobes, upper leaves reducing. Flowers along a spike with white, pink or lavender flower. Flowering between July and December.
Fruit type:
Hairy brown ovoid pod to 25 mm long, with simple hairs at the distal end longer than at the proximal end.
Embryo type:
Seed collecting:
Collect maturing pods those turning pale brown with hard seeds inside. Be gentle with the pods as they split open easily.
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 95%.
Seed germination:
This species has physiological dormancy that need to be overcome for the seed to germinate.
