Name derivation:
Ixodia from the Greek 'ixodes' meaning sticky (from the Greek 'ixos' meaning mistletoe or birdlime); referring to the plant being sticky. Achillaeoides means resembling the genus Achillea (named after the Greek warrior Achilleios, who reputedly used plants from the genus to patch-up wounds). Alata from the Latin 'alatus ' meaning winged; referring to the winged stems.
Distribution:
Found in the southern part of South Australia, growing on a wide range of soils in forest, woodland and scrub communities. Also found in Victoria.
Status:
Native. Common in South Australia. Common in Victoria. More common following a fire.
Plant description:
Erect shrub or undershrub to 2 m high, stems with wings to 2 mm wide extending from the leaf bases, aromatic and viscid. Leaves narrowly lanceolate to linear, to 90 mm long and 9 mm wide. Flower-head open clusters at terminal with white papery flowers. Flowering between October and February. This subspecies differ from the other two subspecies by having linear to lanceolate leaves (oblanceolate for I. achillaeoides ssp. achillaeoides and obovate for I. achillaeoides ssp. arenicola) and found mainly away from the coast (coastal cliffs and exposed coastal sand dunes on the bottom of the Eyre and Yorke Peninsulas and Kangaroo Island for I. achillaeoides ssp. achillaeoides and coastal only in the lower South-east for I. achillaeoides ssp. arenicola).
Fruit type:
white to greyish brown papery head.
Seed type:
Dark brown oblong seed to 1.2 mm long and 0.5 mm wide, covered with short hairs.
Embryo type:

Seed collecting:
Collect whole heads that are drying off and turning greyish brown or collect just the seeds by plucking it off with your fingers. Mature seeds are easily removed.
Seed cleaning:
Place the heads in a tray for a week to dry. Then pluck the seeds from the head with your finders. Viable seeds will be fat and brown. 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.
