It is an evergreen tree that can grow 15-27m tall, with brown main shoots bearing whorls of 7-12cm long flexible green cladodes which look like, and perform the function of, leaves but are actually composed of stem tissues; occasionally, a cladode will be forked and produce a bud in the 'v' of the fork. The cones are 6-11cm long, mature in about 18 months, and have flattish scales which open to release the seeds.
