Name derivation:
Erodium from the Greek 'erodios' meaning heron; alluding to the fruit resembling the head and beak of this bird. Carolinianum named after Prof. Roger Charles Carolin (1929-), an Associate Professor at the University of Sydney, plant taxonomist, principal author of Flora of Australia Vol. 35. Brunoniaceae & Goodeniacea, revisional treatments in Geraniaceae and collector of the holotype for this species from Butler's Peak Range near Fowler's Gap in 1956.
Distribution:
Found in the northern part of South Australia, growing in open communities in arid and semi-arid regions. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Uncommon in Western Australia and Queensland. Common in the other states.
Plant description:
Prostrate, decumbent or ascending annual herb to 30 cm high covered with soft glandular hairs. Basal leaves palmatifid with lobes toothed and covered in glandular-hairs both surfaces. Flowers in umbels of 2-6, sepals with glandular hairs, petals blue-purple with bases and veins red. Flowering between May and September.
Fruit type:
Long brown capsule.
Seed type:
Brown ovoid seed (mericarp) to 8 mm long, covered in long white hairs and with a 55 mm long hairy awn-like attachment, pit at the top of the seed without any hairs.
Seed collecting:
Collect matured capsules, those that are turning brown and have exposed brown seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry fro 1 to 2 weeks. If only seeds collected, no further cleaning is required. If other material is collected, use a sieve to separate 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 germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
