Spent the morning hours chasing some small native dandelions of the Erythrosperma section. These small prostrate species inhabit open, sandy soils and only ingrained habits would lead one to classify them as 'weeds' (due to their belonging to the Taraxacum genus).
Identifying Taraxacum microspecies is a mixture of black magic, art, insights, and sheer luck. I managed to arrive at a tentative identification for the two species I photographed. Here is Taraxacum oxoniense (yellow) side by side with the small Daisy Bellis perennis (skye blue).
Nikon D600, UV-Nikkor 105/4.5 + Baader U filter. Daylight. The UV-Nikkor will never win a bokeh competition, but is a darned sharp lens otherwise.
