Horizontal stems subterranean. Upright shoots treelike, many branched, branchlets numerous and strongly differentiated; annual bud constrictions absent; leaves spreading, pale green below lateral branchlets, prickly needlelike, 3.5–4 × 0.9–1 mm. Lateral branchlets round in cross section, 5–8 mm diam.; annual bud constrictions inconspicuous; leaves spreading to ascending, pale green, in 6 ranks, 2 upperside, 2 lateral, and 2 underside, equal in size, linear, 2.4–5.5 × 0.5–1.2 mm; margins entire; apex acuminate, lacking hair tip. Strobili sessile, 1–7 on tip of upright shoot, 12–55 mm. Sporophylls 3.5 × 3.5 mm, apex short, acute, abruptly narrowing. 2n = 68.
