general taxon notes:
Dicranum drummondii represents an interesting complex with different expressions in plant size, color, thickness of leaf margins, and alar cells. Chinese collections of this species and the types of Dicranum caesium, D. diplospiniferum, D. thelinotum, and D. truncicola all fall within these expressions. This complex represents a single, variable species.

Plants usually robust, up to 15 cm high, yellowish green to yellowish brown, shiny, in loose tufts. Stems erect, simple or branched, densely radiculose below. Leaves small and distant below, becoming larger and crowded above, in multi-rows, erect or flexuose when dry, falcate-secund when moist, lanceolate, up to 12 mm × 1.5 mm, contracted at base, gradually narrowed from an oblong-ovate base to a long, keeled or subulate acumen, often distinctly undulate above; margins plane, entire below, irregularly double-toothed, bistratose above; costa slender, occupying ca. 1/10 the leaf base width, shortly excurrent, papillose or sharply serrate at back above, without lamellae; upper cells quadrate to short-rectangular, thick-walled, not porose, papillose on the leaf dorsal surface; basal cells elongate, rectangular, thick-walled, porose; alar cells quadrate, somewhat inflated, multi-stratose (4–5 layered), brownish, not extending to the costa. Dioicous. Male plants dwarfed. Perichaetial leaves convolute-sheathing at the base, abruptly subulate. Setae slender, straight, 3–5 cm long, yellowish, 2–3 per perichaetium; capsules short-cylindric, curved, inclined to horizontal, striate when dry, yellowish brown; opercula conic-rostrate; peristome teeth lanceolate, divided unequally to the middle, reddish brown.
