unbranched and sparingly branched;

axillary hyaline nodules weak;

central strand present.

usually profusely branched;

axillary hyaline nodules absent;

central strand absent.

in as many as 25 pairs, often undulate, mostly lingulate, rounded to obtuse to broadly acute, sometimes apiculate, to 4 × 0.5 mm;

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

vaginant laminae 1/2–3/4 the leaf length, unequal, minor lamina of most leaves rounded and free distally, or narrowed distally and ending on or near costa;

margin ± entire to crenulate-serrulate, sometimes unevenly so distally, elimbate except for a weak limbidium in the proximal parts of vaginant laminae, limbidial cells 1-stratose;

costa ending several cells before apex, oblongifolius-type, distal part of leaf in transverse section showing enlarged cells arranged in a single row;

laminal cells of dorsal and ventral laminae 1-stratose, distinct, smooth, lenticularly thickened but appearing bulging, firm-walled, irregularly hexagonal, 7–12 µm long;

juxtacostal and interior proximal cells of vaginant laminae 1-stratose, smooth, plane, quadrate to ± oblong, larger;

medial marginal cells of vaginant laminae ± elongate, oriented obliquely.

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.
