In Malaya (Pahang and Perak) plants grow on earthen banks of streams; in such places they are swept away by floods before they have attained their full size, but they commonly produce fertile fronds with pinnae to c. 3.0 x 0.6 cm. Young plants with very large simple fronds like the type of Dryopteris holophylla have not been found in Malaya, but the largest adult specimens from Malaya are not different from those from Borneo. In the Philippines the largest simple fronds seen are 18 x 6 cm (sterile) and 13 x 4 cm (fertile). The type of Dryopteris korthalsii has up to 6 pairs of rather small fertile pinnae (4x 1.3 cm); there are similar fronds from Borneo with pinnae 10x2 cm.
Under the name Aspidium menisciicarpon Bl. Mettenius described a specimen of a species of Tectaria from the Philippines; his description was copied by Hooker who transferred the name to Polypodium. Beddome's description of Nephrodium glandulosum (Handb. Suppl. 70) was based mainly on specimens cited which belong to the present species, but in part on the true Aspidium glandulosum Bl. Christensen (Ind. Fil. 1905) confused the present species with A. lineatum Bl. and A. affine Bl.
