A rhizomatous perennial grass of woodland rides and margins, of shady hedge banks and rock ledges, mainly on free-draining, base-rich soils. It often grows in localised patches, suggesting that regeneration is mainly by rhizomatous spread. 0-395 m (Ysbyty Ifan, Denbs.), and up to 485 m in the Scottish Highlands.
There has been little change in the distribution of M. uniflora since the 1962 Atlas, although the increase in records from N. Ireland is a remarkable example of improved recording. It has been lost from the Isle of Man, where it may have been originally introduced.
European Temperate element.
