Stolons slender and creeping, up to 2 m, green, with sparse leaves; lateral branches ascending, 8-20 cm tall, 1-3 times forked, sparse, terete, stem together with leaves 10-15 mm in diam. Leaves spirally arranged, dense, spreading or nearly spreading, lanceolate, 4-8 × 1-1.5 mm, leathery, without transparent hairs, midrib indistinct abaxially, visible adaxially, base cuneate, decurrent, sessile, margin toothed (margins of leaves of aerial shoots subentire), apex acuminate.

Horizontal stems on substrate surface. Upright shoots clustered, mainly unbranched or sparsely branching mainly at base, 1.2--1.6 cm diam.; annual bud constrictions abrupt and conspicuous. Lateral branchlets few and like upright shoots but annual bud constrictions absent. Leaves spreading to reflexed, dark green, linear-lanceolate, (2.5--)5--8 X 0.6--1.2 mm; margins closely and shallowly dentate mainly in distal 1/2; apex sharply pointed, lacking hair tip. Strobili solitary, sessile on shoots, 15--30 X 3.5--4.5 mm. Sporophylls (1.5--)3.5 X 0.7(--2) mm, abruptly narrowed to pointed tip. 2 n = 68.
