Hi @Tapirlord i don’t think it is quadridentatus as it doesn’t have the super hairy, grey foliage? It was also in a relatively undisturbed area, and usually quadridentatus prefers disturbed areas?

This plant is at the end of its life, which can result in the usual covering of cottony hairs becoming fragmented. If you look at the lower cauline leaves you will see some evidence of this. S.quadridentatus is often found in disturbed sites, but that doesn't mean it occurs there exclusively. Most daisy species are prolific spreaders, and this one is no exception so I wouldn't discount it based on the quality of the site necessarily. In terms of other Senecios, there aren't many options with narrow lanceolate leaves and cottony hairs in our region. Only other contender is Senecio campylocarpus which has broader foliage, larger flowers with a deeper base, and occurs in creek margins usually at higher altitude.

According to the map, it is on a suburban nature strip, which would class as a disturbed area.

Thanks @Tapirlord appreciate your time to respond.

@Mike I have updated the location to be more accurate. Thanks for letting me know.

I get location errors too, usually on the first sightings of the day or when I have stopped checking.

Senecio quadridentatus is probably the most common Senecio in dry woodland habitats locally, this is a totally expected site
