Flora of North America species comparison

usually profusely branched;

axillary hyaline nodules absent;

central strand absent.

unbranched and branched;

axillary hyaline nodules weak or absent;

central strand weak.

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.

as many as 22 pairs, ligulate to oblong-lanceolate, obtuse-mucronate to acute, to 4 × 0.3–0.5 mm;

dorsal lamina narrowed proximally, ending at insertion or slightly before;

vaginant laminae 1/2–2/3 leaf length, equal in proximal leaves, unequal in distal leaves, minor lamina ending between margin and costa or rounded and ending on or near costa;

margin entire but sometimes serrulate distally, limbate on all laminae, limbidium confluent at apex or ending a few cells before, limbidial cells 2- to 5-stratose;

costa percurrent or ending in mucro, bryoides-type;

laminal cells 1- to irregularly 2-stratose, smooth, slightly bulging, firm-walled, irregularly hexagonal, many somewhat elongate, 10–16 µm, juxtacostal and basal cells of vaginant laminae somewhat larger, quadrate to oblong.
