Name derivation:
Senecio from the Latin 'senex' meaning an old man; referring to the white pappus attached to the seed. Glomeratus means clustered.
Distribution:
Found on Kangaroo Island, southern  Mount Lofty Ranges to the lower South-east in South Australia, growing in clearings or margins of sclerophyll forests or along roadsides. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Uncommon in New South Wales. Common in the other states.
Plant description:
Erect annual herb to 2m tall with a woody base. Leaves alternating up the stems to 20cm long and 30mm wide, sometimes larger, flat, hairy to slightly hairy. Leaves in the middle third of the stems with basal lobes, somewhat stem clasping, margins coarsely toothed to deeply lobed, the lobes often toothed. Uppermost leaves flat to linear, margins toothed or appearing entire due to rolling. Flower-heads top-shaped to almost globular, green to purple, with yellow to orange flowers, in open groups, often of 50-300 flower heads per stem. Differ to Senecio glomeratus ssp. longifructus by having red-brown seeds, hairs on the seed usually more than 5 mm long and the bases of the flower-heads are often purple. Flowering between November and February.
Fruit type:
Pale brown vase-shaped daisy-head.
Seed type:
Brown oblong seed to 3 mm long and 0.5 mm wide, covered in white hairs and with numerous deep striations, pappus not persisting
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect heads that are fat, hard and turning brown by picking off the whole heads.
Seed cleaning:
Place the heads in a tray for a week to dry. Then rub the heads gently with your hands or a rubber bung 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.
