unbranched and branched;

axillary hyaline nodules absent;

central strand absent.

in numerous pairs, lanceolate to linear-lanceolate, frequently somewhat falcate, acute, to 7 × 0.6 mm;

dorsal lamina narrowed proximally, usually ending before insertion;

vaginant laminae 1/3–1/2 the leaf length, unequal, minor lamina usually rounded and free distally or narrowed and ending on or near costa;

margin ± entire, elimbate;

costa ending 15–35 cells before apex, bryoides-type;

laminal cells usually 1-stratose, sometimes 2-stratose juxtacostally, quadrate to short-oblong to hexagonal, smooth, slightly bulging, ± firm-walled, 15–23 × 10–18 µm in dorsal and ventral laminae, juxtacostal cells largest.

as many as 12 pairs, oblong to lingulate, broadly acute to obtuse, sometimes apiculate, to 1.4 × 0.5 mm;

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;

costa ending 2–6 cells before apex, bryoides-type;
