Leaves opposite, 2-5 mm, connate to 1/2-3/4 their length, not photosynthetic; bases thickened, brown, persistent, becoming hard, enlarged, and black; apex setaceous. Pollen cones 2-several at node, obovoid, 5-7 mm, sessile; bracts opposite, 6-10 pairs, light yellow and slightly reddened, ovate, 2-4 × 2-3 mm, membranous, slightly connate at base; bracteoles slightly exceeding bracts; sporangiophores 2-4 mm, 1/4-1/2 exserted, with 5-8 sessile to nearly sessile microsporangia. Seed cones 2-several at node, obovoid, 6-10 mm, sessile or on short, scaly peduncles; bracts opposite, 4-8 pairs, ovate, 4-7 × 2-4 mm, membranous or papery, with yellow center and base, margins entire.
