Moehringia trinervia

Tracheophyta MagnoliopsidaCaryophyllaceaeMoehringiaMoehringia trinervia


An annual of open, often moist, ground, generally found in woodland but also in shaded hedge banks, and rarely in unshaded places such as on walls and railway banks. It favours slightly acidic substrates, and there is a slight preference for warmer slopes in woodland, which hastens the successful completion of the plant`s life-cycle. 0-425 m (Mallowdale Fell, W. Lancs.).
