Census of South Australian plants (external link)     [genus Senecio]
Name derivation:
Senecio from the Latin 'senex' meaning an old man; referring to the white pappus attached to the seed. Gregorii  named after Sir Augustus Charles Gregory (1819-1905), an English-born Australian explorer and surveyor-general and collecter of the type specimen from Coopers Creek.
Distribution:
found in the northern part of South Australia, growing in a variety of soils in river beds, plains, dunes and margin of saline swamps, in herbfield, shrubland and woodland. Also found in all mainland states.
Status:
Native. Common in South Australia. Rare in Victoria. Common in the other states.
Plant description:
Glaucous, annual herb to 50 cm high. Stem leaves narrow-linear to 10 cm long, undivided, base narrow. Inflorescence 1-5 on a stem with large yellow daisy-flowers. Flowering between July to December but possibly throughout the year depending on rainfall.
Fruit type:
Large daisy-head with exposed yellowish pappus.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect heads that are large and fluffy. Either pick off the whole heads or use your finger and pull off the seeds from the head. Mature seeds will come off easily.
Seed cleaning:
Place the heads in a tray for a week to dry. No cleaning is required if only pure seeds are collected. If heads are collected, then rub the heads gently with your hands to dislodge the seeds. Viable seeds will be fat and hard. 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.
