Stipe about equal in length to lamina, fleshy when young, dark green to brown, flattened on upper surface, grooved; scales narrow, pale brown, numerous near base, scattered above; hairs sometimes present. Lamina 1–2-pinnate, oblong to narrowly triangular, mid-green to dark green, with short, soft hairs on upper surface of rachis, veins and veinlets; rachis groove not continuous with groove of lamina midrib. Primary pinnae shortly stalked or sessile, lobed to pinnate; lobes broadly oblong to deltoid, margins crenate to shallowly toothed, apices blunt; veins simple or forked.

Kato (1984) recognizes 3 subspecies and 2 varieties of Deparia petersenii. Deparia petersenii subsp. congrua is distinguished from the other two subspecies by the thicker rhizome and stipe, the comparatively close-set, soft fronds, the more or less oblique pinna-segments, and the gradually narrowed, narrowly triangular, long-acuminate leaf apex.
