as many as 12 pairs, oblong to lanceolate, acute to obtuse-apiculate, most ending in a clear, sharp cell, to 1.8 × 0.4 mm;

dorsal lamina narrowed or rounded proximally, ending at or before insertion, not decurrent;

vaginant laminae 1/2–2/3 leaf length, unequal, minor lamina ending near margin;

margin serrulate, limbate and entire to remotely denticulate on proximal 2/3 or less of vaginant laminae of most leaves of perichaetial stems, often absent from leaves of infertile stems, limbidium intralaminal in part or completely, limbidial cells 1-stratose;

costa ending 2–4 cells before apex or percurrent, ending in apiculus, infrequently short-excurrent, bryoides-type;

lamina cells 1-stratose, pluripapillose, obscure, firm-walled, rounded-hexagonal, 5–8 µm, twice as deep as wide.

dorsal lamina narrowed proximally, ending at insertion, not decurrent;

vaginant laminae ± 1/2 leaf length, ± unequal, minor lamina ending near margin;

margin crenulate-serrulate but limbate and entire on proximal 1/3–1/2 of vaginant laminae of most leaves, limbidial cells 1-stratose;
