Yellow dandelion type daisies are pigs to ID. A pity you did not take a photo of the flower side on to show the bracts at the base of the flower head. It might be a good idea to move photo 1 to photo 3. I thought initially it was of stinkwort and did not realise it was of the basal leaves of the daisy.

The drooping attitude of the flower bud and the long narrow lanceolate leaves are typical of Microseris lanceolata.

Thanks Michael!
I've just noticed the thing Michael M has put up on the homepage too

With Microseris walteri now on the ACT plant list, and impossible to tell from Microseris lanceolata from a photo of a flower, Michael M has made the rule of thumb - walteri under about 700 m, sp. about 700-1000 m, and lanceolata over about 1000 m altitude.

Julie in case you didn't see the comments Betty reverted the identification to genus level for a reason - do you have any countering basis for the confirmation?

Microseris lanceolata, according to Vicflora, occurs only in subalpine to alpine areas. Microseris walteri is the common lowland species. Unfortunately, the only way to tell them apart is to count the number of bristles on the seeds or to dig them up in autumn to see whether they have roots or tubers. Much of the ACT is neither lowland nor subalpine, hence Michael Mulvaney's rule of thumb.

After the problems I was having yesterday with sightings, some of which were Microseris walteri and some Microseris sp. on the same mountain, Michael M has decided it is more sensible to change the rule of thumb to walteri under about 1000 m altitude, and lanceolata over about 1000 m.

This is news to me I have always considered Microseris lanceolata to be the lowland form and Microseris scapigera (without tubers) the alpine form. I haven't heard of M.Walteri.

More information concerning the three species of Microseris can be found here: https://www.rbg.vic.gov.au/documents/MuelleriaVol_34_-_p63_Walsh.pdf . The determination of the distribution of the ACT species and factors influencing that distribution could make for a good mid-year honors student project. Given the recognition of M. walteri it may be that the removal of M. lanceolata from the ACT rare plant list might have been a little premature.
