as many as 16 pairs, oblong to lanceolate, acute to short-acuminate, to 1.3 × 0.25 mm;

dorsal lamina narrowed proximally, ending well above or at insertion;

vaginant laminae ± 4/5 leaf length, ± equal, minor lamina ending on or near margin;

margin ± entire to crenulate-serrulate, limbate on all laminae, limbidium variable, developed best on vaginant laminae, ceasing well before apex, limbidium cells 1-stratose;

costa ending 2–5 cells before apex to percurrent, bryoides-type;

laminal cells 1-stratose, distinct, smooth, somewhat bulging, firm-walled, irregularly quadrate to hexagonal, 9–14 µm, increasing somewhat in size and ± oblong in proximal parts of vaginant laminae.

as many as 80 pairs, somewhat undulate, oblong, obtuse to broadly acute, usually bluntly mucronate, to 4 × 1 mm;

dorsal lamina rounded proximally, ending at insertion;

vaginant laminae 1/2 the leaf length, acute, ± equal, minor lamina ending on or near margin;

margin entire but denticulate distally, elimbate;

costa percurrent to ending 2–4 cells before apex, taxifolius-type;
