Shrubs erect, 0.5–5 m. Bark gray, cracked and irregularly fissured. Branches alternate or whorled, rigid, angle of divergence about 30°. Twigs pale green, becoming yellow, then gray with age, glaucous, with numerous very fine longitudinal grooves; internodes 3–10 cm. Terminal buds spinelike, to 10 mm. Leaves in whorls of 3, 5–15 mm, connate to 1/2–3/4 their length; bases becoming gray and shredded with age; apex spinose. Pollen cones 1–several at node, obovoid, 6–10 mm, on short, scaly peduncles; bracts in 8–12 whorls of 3, reddish brown, obovate, slightly clawed, 3–4 × 2–3 mm, membranous; bracteoles nearly equaling bracts; sporangiophores 4–5 mm, exserted to 1/4 their length, with 4–5 short-stalked microsporangia. Seed cones 1–several at node, obovoid, 10–15 mm, on short, scaly peduncles (rarely sessile); bracts in 6–9 whorls of 3, circular, 8–12 × 8–12 mm, papery, translucent with reddish brown center and base, base clawed, margins entire.
