Diagnosis
Main axes 3–6 mm wide and at least 160 mm long, with internode length 20–60 mm. First-order branches 0.9–2.5 mm wide and up to at least 125 mm long. Second-order branches about 0.7 mm wide and up to at least 68 mm long, borne alternately with internode length 12–22 mm. Sterile ultimate appendages inserted at right angles on axes; those on first-order branches restricted to proximal region, 7–11 mm long; those on second-order branches 4–5.3 mm long. Fertile appendages with axes 0.3–0.7 mm wide at base and extending 1.7–4.0 mm to point of initial dichotomy to form two sister branches; each branch recurved distally, dividing dichotomously three or four times to support at least 12 sporangia, and with an overall length of 1.8–4.2 mm; penultimate divisions of fertile appendages each bearing two to four small fusiform sporangia that are grouped into a truss. Sporangia 1.0–1.4 mm long and 0.3–0.5 mm wide.
