Hi Maggi,
There are not enough days in the year to look at all the mountains and all the plants- you only get vignettes. ( the two Eyre mountains excursions involved too much walking to do much photography)
"scrithalis" refers to the scree habitat of this particular Ranunculus.
Myosotis macrantha is widespread but is not particularly common. Having said that someone told me about seeing the plant growing like daisies on a lawn behind Larrikin Creek hut on the Thousand Acre plateau. When I was there last year I found only one plant. The flowers come in a wide range of shades generally in combinations of red/brown/gold. My guess is that it is scented. Dave might know as he is good a picking up scented flowers on account of the way he photographs them - he drew my attention to a tiny scented Leptinella on one occasion
