Leaves in whorls of 3, 2–6 mm, connate to 2/3–3/4 their length; bases splitting at margins, persistent, forming black, thickened collar; apex acute. Pollen cones 1–3 at node, narrowly ellipsoid, 5–8 mm, on very short, scaly peduncles (rarely sessile); bracts in 6–9 whorls of 3, light yellow, ovate, 3–4 × 2–3 mm, membranous, base short-clawed; bracteoles equaling bracts; sporangiophores 3–5 mm, exserted to 1/3 their length, with 3–7 sessile to short-stalked microsporangia. Seed cones 1–3 at node, lance-obovoid, 8–15 mm, on short, scaly peduncles (rarely sessile); bracts in 6–9 whorls of 3, obovate, 4–8 × 3–5 mm, papery, yellow-translucent with green-yellow center and base, base broadly clawed, margins slightly dentate.
