The lower side branches bear dense needle-like leaves whose tips extend into threads.
The sporangial spikes are cylindrical, 1–4 cm long and 0.3–0.4 cm across, and are borne 1–3 at the tips of the twigs of the branches.
The sporophylls are broadly ovate, with tips drawn out long into threads and becoming membranous.
