--><p>The outer perigonial leaves of Aulacomnium have flaring apices; the inner leaves are concave with narrowed limbs and broad or conspicuously broad bases. The outer perichaetial leaves sometimes have flaring apices; the inner leaves are narrowly lanceolate and plicate with erect, long-acuminate apices and margins sometimes serrulate at the apex. The basal laminal cells of cauline leaves of this genus are large and smooth.</p>
