Uniquely identifiable characteristics (but only when in flower)
Distinguishing Feature : Thistle flowers on no or ultra-short flower stalks.
Dwarf Thistle grows in short un-improved grassland on chalk or limestone. They occur in the White Peaks area, and in the South East of the UK. They is virtually no presence north of Filey on the East coast, nor any west of Taunton in Devon. Draw a line linking those two towns and most occurrences are SE of that line, with large areas missing. It is not rare, but your Author has never knowingly seen it in flower, although he may have attempted to sit on a basal rosette of it in his youth whilst walking the hills (but it could have been the basal rosette of some other thistle not yet in flower).
