Morphology Leaves Leaf lamina
Lamina herbaceous to subcoriaceous, dark green, quinquangular, to 145 × 100 cm, 3-pinnate to 4-pinnatifid. Lamina adaxially glabrous, abaxially both vascular system and lamina covered in stout white hairs and tiny glands

Morphology Leaves Leaf veins
Veins free, not reaching margin, catadromous except near apex of pinnules, with few stiff, spreading hairs on lower surface,
Morphology Leaves
Costae with 3–4-celled brownish appressed hairs. Fronds tufted, gemmiferous.

Figures

Ecology
Riverine and swamp forest; 1130–1200 m
Conservation
Widespread; least concern (LC)
Note
Christensen based Dryopteris subcoriacea directly on Polypodium vogelii Hook., as a new name was necessary in Dryopteris due to the presence of D. vogelii (Hook.) C.Chr., based on Aspidium vogelii Hook. (1854). The lectotype for D. subcoriacea is therefore the same as for Polypodium vogelii.
