SA Census:
Census of South Australian plants (external link)     [genus Harmsiodoxa]
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.
Distribution:
Found across the northern part of South Australia, growing in sandy soil. Also found in the Northern Territory, Queensland, New South Wales and Victoria.
Status:
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:
Bent.
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.
