Horizontal stems on substrate surface. Upright shoots clustered, shoots 0.5--0.8 cm diam., dominant main shoot branches 2--3(--4), mostly in lower 1/2. Lateral branchlets few and like upright shoots; annual bud constrictions abrupt and conspicuous, shoots 0.5--0.8 cm wide, branches mostly erect. Leaves ascending to appressed, medium green, 3--5 X 0.4--0.7 mm; margins entire; apex with narrow hair tip 1--3 mm. Peduncles 3.5--12.5 cm, with remote pseudowhorls of appressed leaves, unbranched. Strobili solitary (if double, usually nearly sessile), 20--55 X 3--5 mm. Sporophylls 1.5--2.5 mm, apex rather gradually reduced to hair tip. 2 n = 68.
