Costules have a size of 4-5 mm. Common veins are 12 pairs. The lamina segment is hard, rough on the bottom and fibrous edges. Sori is exindusiate, near costule and pale paraphrase is no more than sporangia.

The scales and hair on the pinnae-rachis are prickly, pale and shiny. The lower surface of the costae initially carries a pale setifer scales scattered within 3mm or shorter than distal. It often causes caduceus and leaves the glabrous costae.

Costule with small scales, tufted and pale, mostly caduceus, some hairs present towards the top of the pinnules on the costae but are varied. Veins may have thick, stiff hair and vary in number.

Spikes are easily found at an altitude of 200-1,600 m. Leaf shoots that are still curled are used as vegetable ingredients. Fine hairs are used for boiled medicinal herbs. Stems are often used as a growing medium for orchids, Anthurium, Piper, Platycerium, Adiantum and other fern species. Sometimes finely chopped to medium in the pot.

Large stems are preferred for home decoration poles. This fern species has a strong trunk and is often also used as handicraft, material for building, used in Hindu traditional ceremonies and used as fuel.
