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 6 pairs, lanceolate, acute to obtuse, sometimes apiculate, to 2.2 × 0.5 mm;

dorsal lamina narrowed proximally, ending at insertion, not decurrent;

vaginant laminae 1/3–1/2 leaf length, equal;

margin entire but sometimes ± serrulate distally, limbate, limbidium 1–2 cells wide, ending before apex, often indistinct on vaginant laminae, limbidial cells 1-stratose; ecostate, or costa consisting of very short proximal vestige;
