Rhizome much-branched, glabrous. Fronds solitary or clustered, 5-90 cm long. Stipes glabrous. Leaflets broadly obovate to broadly cuneate, 25-45 mm long, 20-40 mm wide (smaller in terrestrial forms), often streaked with brown false veins between the true veins on the lower surface, green distally, yellow-green proximally, separated by a brown zone, glabrous (a few basal scales in terrestrial forms); outer margin rounded, entire. Sporocarps in groups of 2-4; stalks 10-20 mm long, branched 1-3 times (rarely unbranched), arising at or near the base of the stipe, glabrous or with a few basal scales; conceptacles globose, 3-6 mm long, glabrous to densely scaly; basal teeth absent.
A fern with a long creeping rootstock. It grows 5-25 cm high. It often grows in long stands and the rootstock has few branches. The leaves have two tones forming a decorative marking. The stalks are 5-25 cm long and occur singly or in clusters. The leaflets are 2-5 cm long by 2-4 cm wide. They are broadly oval or wedge shaped. The spore body stalks are longer than the capsules and are branched 1-3 times. The capsule is 0.3-0.5 cm long and oval.
Aquatic fern. Rhizomes submerged, long-creeping, rooting at nodes. Lvs solitary at each node, glabrous; stalks to 25 cm long, each terminating in 4 flabellate segments; each segment rounded on outer margin, to 2-3 × 2-3 cm, green, sometimes with a horizontal brown band in the cente. Sporocarps 3-5 mm long, hairy or becoming glabrous, solitary or in groups of 2-4, on branched stalks to 2 cm long.
