--><p>Bartramia is generally recognized by its linear-lanceolate leaves and sheathing base with a distal lamina that is 2- or 3-stratose at the margins or throughout. The plants may be soft or rigid; the stem cortical cells have somewhat firm walls. The leaves are not plicate; the basal laminal cells are pale and smooth with walls thin or rarely thick toward the costa. The perichaetial leaves are usually less prorulose with more lax areolation; the exostome teeth are sometimes cleft distally and lack intermediate abaxial thickenings. Bartramia stricta lacks a sheathing leaf base but otherwise is in accord with the generic concept.</p>
