UK Status

Mainly in southern Britain and parts of East Anglia scattered elsewhere and possibly decreasing.

VC55 Status

Near scarce in Leicestershire and Rutland. In the 1979 Flora survey of Leicestershire it was found in only 1 of the 617 tetrads. The Leire find is the first Leicestershire record since 1983.  It is known from several sites in Rutland.

In the current checklist, (Jeeves 2011) it is listed as Native; now scarce and confined to the Oolite.

It was on the 2011 VC55 Rare Plant Register (Jeeves, 2011) but does not meet the criteria for the current RPR (Hall and Woodward, 2022)
