Diagnosis
Sterile axes 3.0-5.2 mm (av. 4.1 mm) wide, dividing at least 2-3 times. Fertile axes, 3.2-4.0 mm (av. 3.6 mm) wide, at least 11.6 cm long, branched at least 4-5 times, 4.2-19.0 mm apart, branching angles 30°-60°, finally forming distal-terminal branchlets usually less than I mm wide. Sporangia borne laterally on short stalks, inserted at narrow angles, or below branching point of main axis. Many could be gathered into a spike, which is 8-48 mm long and 6.2- 9.3 mm wide at the middle part. Sporangia, ovoid to pear-shaped in face view, usually 3.0-6.4 mm (av. 4.9 mm) wide and 2.5-5.0 mm (av. 4.2 mm) high. Sporangial stalks, 1.5-4.5 mm (av. 2.8 mm) long, 0.3-1.0 mm (av. 0.7 mm) wide at base where they depart from the axis, widening distally at the junction with sporangium to 1.3- 3.5 mm (av. 2.4 mm) wide. Rim of sporangium about 200 μm wide. Spores are 48-77 μmin diameter, subcircular to circular in outline; trilete rays distinct, 3/4 to whole radius, with curvaturae perfectae, exine thin, shagrenate.
