Name derivation:
Erodiophyllum from the genus Erodium and the Greek 'phyllon' meaning leaf; referring to the resemblance of the leaves to those of some Erodium species. Elderi named after Sir Thomas Elder (1818-1897), a Scottish-Australian pastoralist, highly successful businessman, philanthropist, politician, race-horse owner and breeder, and public figure.
Found mainly in the eastern part of South Australia with old records from the west and north-east, growing on alluvial floodplains in mulga shrubland with chenopods. Also found in Western Australia and New South Wales.
Native. Common in South Australia. Very rare in New South Wales. Uncommon in Western Australia.
Plant description:
Rough-hairy perennial forb with stout erect stems. Leaves to 10 cm long and 3 cm wide, deeply lobed and broad-toothed, bright green, hairy. Flower-heads on thick hairy stems with a large blue-violet or white daisy with yellow centre at the end. Flowering between April and November.
Fruit type:
Hard, woody, brown egg-shaped fruit-head to 25 mm long, covered with rigid spreading points.
Seed type:
Pale brown arrow-shaped seed to 4 mm long and 2 mm wide.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect maturing heads, those that are fat, hard and turning brown. Fruit-heads can be picked from the stalk or collected from the ground. Be careful as fruit-heads can be spiny.
Seed cleaning:
Place the fruit-heads in a tray and leave to dry for at least two weeks. No further cleaning is required if only fruit-heads were collected. Each fruit-heads contain numerous seeds. Store the whole fruit-heads 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 two collections, the seed viability were high, at 100%.
