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 lingulate, apex broadly acute to rounded, apiculate or mucronate, margins revolute or occasionally plane, often bordered proximally with rectangular cells usually hidden in the revolute margins;

costa percurrent or ending in apiculus or short mucro, with an adaxial pad of swollen cells similar to those of the lamina, distally broad, (4–)6(–8) cells across adaxial surface;

distal laminal cells subquadrate, 9–13(–18) µm wide, µm, 1:1; strongly papillose.
