central strand present.

usually unbranched;

axillary hyaline nodules absent;

central strand weak.

as many as 15 pairs, often undulate, oblong to lanceolate, obtuse to broadly acute, cuspidate, to 2.7 mm × 0.6 mm;

dorsal lamina truncate-rounded proximally, ending at insertion, not decurrent;

vaginant laminae 2/3 the leaf length, ± equal, minor lamina ending on or near margin;

margin evenly serrulate, often crenulate-serrulate on dorsal and ventral laminae, elimbate;

costa ending in cuspidate apex, taxifolius-type;

laminal cells 1-stratose, distinct, smooth, bulging, firm-walled, irregularly hexagonal, 8–11 µm frequently paler at margin, conspicuously mammillose in vaginant laminae, larger and clearer juxtacostally.

as many as 40 pairs, lanceolate to oblong-lanceolate, generally broadly acute, 0.4–1.5 × 0.2–0.3 mm;

dorsal laminae narrowed proximally, often ending well before insertion;

vaginant laminae 1/2–3/4 leaf length, ± equal, minor lamina ending on or near margin;

margin entire but often ± serrate distally, limbate on the vaginant laminae, infrequently limbate on dorsal and ventral laminae of perichaetial leaves, limbidial cells 1-stratose;

costa usually ending 2–3 cells before apex, bryoides-type;

laminal cells 1-stratose, distinct, smooth, slightly bulging, firm-walled, irregularly quadrate to hexagonal, 8–11 µm.
