Selliguea feei Bory

Rhizome 3-8 mm thick, internodes to 1-4.5 cm long; vascular strands with bundle sheath fully sclerified; sclerenchyma strands absent. Rhizome scales peltate (rarely pseudopeltate), appressed to spreading (more often), 5-6.5 by 1.5-2.5 mm, obtuse to acute (mostly), brown, evenly coloured, entire to (rarely) remotely and weakly dentate. Fronds simple, dimorphic. Fertile fronds with stipe 4-30(-55) cm long; lamina 7-25 by 2-7 cm, index 3.1-7.7, widest at 0.3-0.5 from base. Sterile fronds with stipe 2.5-45 cm long; lamina 5-31 by 2-10 cm, index 2.2-2.8, widest at 0.2-0.4 from base. Venation: main veins on upper surface not raised to raised, distinct; veinlets free and anastomosing, free veinlets excurrent and recurrent. Hydathodes frequent, calcareous scales not persistent. Margin cartilaginous, thickened; without notches or notches sporadically present. Sori mostly confluent across connecting veins into interrupted transverse coenosori, in one row between adjacent main veins, 3-5 mm wide, superficial.
