Pinnules deltate in outline, pinnatisect, with 2–7 segments, the ultimate segments with 2–4 narrowly linear obtuse apices to 0.4 mm wide, with occasional scales. Rhachis rather densely set with long-tapering scales, often with rather dense stalked glands – but these often absent on young/infertile fronds.
