2010.04.06 Austria, Lower Austria, district Bruck/Leitha (Braunsberg, 155 m AMSL).Of the species aggregate T. officinale agg..This one belongs to a population which one can find commonly in Vienna and eastwards: reddish, felted stem, and also leaves with sharp-ish edges - which is not at all typical for the most common genera of T. officinale agg.: ordinary populations (also growing in the same habitats, by the way!) have more round-ish ones.The species shown here belongs to section ruderalia (according to Fischer & al., Exkursionsflora 2008, 3rd) but at least to me seems to show some transitional features towards section hamata (the latter being very rare in Austria, and not present in the habitat where the one shown here is to be found).As specimens of Taraxacum officinale with those characteristics ("felted/reddish") are to be found in a greater region (side by side with "ordinary" ones) this could possibly be some sub-species "behaving" like a species proper.

this one which (even though much smaller, possibly due to the harsh habitat) shows similar morphological characteristics.Very common.German name: [Filzig-rtlicher?!] Lwenzahn
