as many as 20 pairs, elliptic to broadly lanceolate to oblong-lingulate, acute, short-acuminate to obtuse-apiculate, to 2 × 0.5 mm;

dorsal lamina narrowed proximally, ending before insertion to ± decurrent;

vaginant laminae 2/3–3/4 leaf length, equal;

margin ± entire but usually serrulate distally, limbate on all laminae, limbidium usually ending a few cells before apex, frequently edged by 1–2 rows of quadrate to oblong chlorophyllose cells in proximal parts of vaginant laminae, limbidial cells 1–2-stratose;

costa percurrent to ending 2–5 cells before leaf, infrequently short-excurrent, bryoides-type;
