The whole plant and nothing but the plant. Another specimen (not shown, for your Author would need to make a much longer photo to see any detail - as it is, the photo has been considerably reduced) was just short of twice this length!


It is native and grows on dry rich grassland which is limestone or sandy-based - i.e. limey or slightly acidic such as sand dunes near the sea; less often on inland sandy soils. It occurs throughout England, preferring the calcareous soils in the South, in the West it is mainly coastal; in the East grows much further inland except in Cumbria and yorkshire where it straddles the whole country.
