Plants to 0.5 cm. Stem leaves stiff, erect-appressed when dry, ovate-oblong to oblong-ligulate, 2–2.8 mm; margins revolute, entire or rough near apex by means of projecting papillae; apex rounded-obtuse, often mucronate, carinate; basal laminal cells rectangular to short-rectangular, walls thin, not nodose; distal cells 13–19 µm, 1-stratose, papillae 2 per cell, conic, small.

Discussion
Orthotrichum flowersii is distinguished from O. pallens and O. pumilum by its blunt, carinate leaves that are ovate or ovate-oblong, almost always with a small mucro. The leaf apices are subcucullate; the stomata are found in one or two rows mid capsule.
