Scapania (order Jungermanniales) A large genus of leafy liverworts, in which the thallus is small to large and robust. The leaves occur in 2 ranks; each leaf is divided into 2 lobes, the smaller lobe being folded back over the larger, posterior one and appearing at first sight to be a separate leaf. They are found on rocks, on peat, on tree roots, etc., generally in moist, shady, non-calcareous habitats.
