Main stems 2–3 mm in diameter, bearing dorsal and ventral leaves rather sparsely near base, subdichotomously branching: ultimate branchlets narrowing towards apex, about 7 cm long, to 1.2 cm wide. Ventral leaves patent or slightly ascending, oblong, more or less falcate, acuminate, or in some cases moderately acute at apex, widened at base, to 6 mm long, 2 mm broad, with transparent edges, minutely denticulate at margin; pseudoveins present at both sides of veins, though in some specimens obscure; dorsal leaves imbricate, ovate-oblong with long acuminate apex, to 1.5 mm long except the needle-like apices or about 1 mm in length, dentate at margin. Spikes to more than 5 cm long, about 1.5 mm in diameter; sporophylls oblong subdeltoid, acuminate at apex, about 1.5 mm long, 1 mm broad, dentate at margin.

Notes: This species is similar to Selaginella doederleinii Hieron. Of China and Japan but differing in the larger size of the plants as well as of the leaves and stems, in the thicker texture with more deeply green colour of the upper surface of the leaves, and in the presence of false veins between the veins and the edge of the leaves. The branching of the stems is dichotomous, though that of the other species is pinnate.
