Pagong-pagoñgan is a climbing epiphyte with slender rhizomes covered with peltate scales, creeping on trunks and branches. Fronds are of two kinds: sterile and fertile. Sterile fronds vary from elliptic to round, 1 to 5 centimeters long, 1 to 2 centimeters wide, with a rounded apex and a cuneate base. Fertile variety is narrower, 3 to 15 centimeters long, 3 to 10 millimeters wide, on stipes up to 2 centimeters long. Sori are arranged in a broad and submarginal line, not rarely filling the whole surface of the fertile frond.

• Antibacterial: Study was done on the antibacterial activity of water, ethanol and chloroform extracts of Dp against E coli, S pneumoniae and S aureus. Antibacterial activity against gram-positive bacteria was detected only in the water extract.
• Antifungal: Study showed the chloroform and ethanol extract of Dp possessed mild activity against Trichophyton spp. The water extract was devoid of antifungal activity. The antifungal activity was less potent than griseofulvin, fluconazole and itraconazole. Future studies may produce a potential for the treatment of Athlete’s foot.
