as many as 28 pairs, sometimes ± undulate, oblong, obtuse-apiculate to acute, to 2.4 × 0.3–0.4 mm;

dorsal lamina narrowed proximally, ending before or at insertion;

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

margin evenly crenulate-serrulate but irregularly serrate distally;

costa ending 6–16 cells before apex, covered and obscured above by chlorophyllose cells, taxifolius-type;

lamina cells irregularly 2-stratose, smooth, bulging, firm-walled, irregularly rounded-hexagonal, 7.5–10 µm. Sexual condition gonioautoicous and cladautoicous;

perigonia gemmiform, axillary, and on short branches;
