Flora of North America species comparison

leaves stiff, loosely erect-appressed when dry, narrowly lanceolate to oblong-lanceolate, 1.4–2.9 mm;

margins strongly revolute to just before apex, entire;

apex obtuse to bluntly acute, not incurved when dry;

basal laminal cells subquadrate to short-rectangular, walls thin, not nodose;

distal cells 8–10 µm, 1-stratose, lumina irregular due to uneven wall thickenings, papillae 1–2 per cell, conic, low.
