Name derivation:
Alyogyne from the Greek 'alytos' meaning undivided and 'gyne' meaning woman; referring to the undivided style. Huegelii named after Baron Carl von Hugel (1795-1870), an Austrian traveller, plant collector and patron of horticulture.  He collected plants in Western Australia in 1833 and also in the Philippines.
Distribution:
Found mainly across the Eyre Peninsula and the Southern Flinders Ranges with an isolated collection from the northwest region, growing on a variety of soil types and habitats. Also found in Western Australia.
Status:
Native. Common in South Australia. Common in Western Australia.
Plant description:
Erect perennial shrub to 2 m tall, with 3-5 deeply lobed hand-liked leaves covered in hairs. Inflorescence large solitary white, cream, red, blue or purple flower. Flowering between June and January.
Fruit type:
Hairy brown papery ovoid capsule containing a few seeds.
Seed type:
Segmented brown seed to 4 mm long and covered in short brown hairs.
Embryo type:
Folded.
Seed collecting:
Collect capsules that are drying off and starting to turn brown. The seed inside should be brown and hard.
Seed cleaning:
Place the capsules into a tray and leave to dry for a week. Then rub the capsules 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 two collections, the seed viability was average to high, ranging from 60% to 85%.
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).
