- Diagnosis
- Main axes up to 1 cm wide, more than 29 cm long, bearing spirally arranged branch systems consisting of one or two more orders of branching. First order branches 3-4 mm wide, more than 24 cm long. Second and third order branches arranged alternately and distichously. First one or two second and third order branches anisotomously dichotomous to almost monopodial, 1-3 cm high, with 6-7 divisions. Aphlebiae in pairs at base of branch axis, opposite, 5-8 times dichotomous and non-laminate. Aphlebiae decrease in size and number of divisions distally on branch axes. Ultimate branchlets borne on second or third order branch axes, 2-4 mm high, 4-5 X dichotomous, decreasing in size and number of divisions distally on branch axes. Some secondary branches with aphlebiae and ultimate branchlets terminated by sporangia. Sporangia ovoid, 2 mm x 1 mm, with no apparent annulus. Dehiscence longitudinal. Epidermal pattern obliquely striated. Spores round, trilete, about 30μ in diameter, smooth to finely granulose.
