Flora of North America species comparison

ovate to oblong-lanceolate, apex acute, mucronate to short-awned, occasionally comparatively long-awned, margins recurved proximally to nearly plane, not or weakly bordered distally with slightly thicker-walled cells;

costa excurrent, lacking an adaxial pad of cells, distally narrow, 2(–3) cells across adaxial surface;

distal laminal cells distally quadrate-hexagonal, width 13–17 µm, 1:1, weakly simply papillose or smooth.

ovate to oblong-lanceolate, apex broadly acute to rounded, mucronate to short-awned, margins revolute in mid 2/3–3/4 of leaf, weakly bordered from apex to near base with (2–)4 rows of weakly thicker-walled and less-papillose or smooth cells;

costa excurrent, lacking an adaxial pad of cells though convex adaxially, distally narrow, 3–4 cells across adaxial surface;

distal laminal cells subquadrate to hexagonal, occasionally somewhat elongated longitudinally, width 13–18 µm wide, 1(–2):1, papillose with 4(–6) simple papillae per lumen.
