Fronds distantly pinnate or bipinnate, with stout, often geniculate main axes and slender branches, often pendent; shoots 3-5 mm wide, and up to 10 cm long. Stems red-brown, 0.20-0.25 mm in di-a meter. Leaves (1.2-)1.5-2.5(-3.2) mm long, approximate or distant, oblong, 1.7-2.2 x as long as wide (but appearing narrower in situ because of the recurved leaf margins-the leaf also transversely shrunken when dry), spreading at an angle of about 50-90° to the stem; the dorsal margin nearly straight, rather longly decurrent at its base in a very narrow wing; the ventral margin straight or weakly arched, narrowly revolute for a varying length at its base, the revolute portion diverging from the insertion at an angle of about 45°, and either grading into the plane distal part or, in the largest leaves, with a pronounced angle at the transition. Usually with a few large teeth around the apex of the leaf, the ventral margin entire or with 1-2 distant teeth, chiefly in the distal part. Cells in the middle and proximal part of the leaf(and sometimes also distally) elongate, 18-21 µm wide x 24-35 µm long, 1.5-2.0 x as long as wide, trigones moderate or small, with longitudinal walls thicker than the transverse walls; oil bodies Calypogeia-type, 4-10 per cell. Perianths conical with a dorsal wing.
