Uniquely identifiable characteristics

Distinguishing Feature :

A fairly rare [RR] plant which grows up to 4cm high not in marshes as its common name might suggest but on fairly wet heaths. It exhibits a clear sky-blue colour with white and grey or green streaks on the outside of the petals, and grey spots on the inside. Leaves are narrow linear. It is to be found very locally in places such as Dorset to East Sussex through to North East Yorks and Westmorland but is decreasing.
