D. brunnescens was based on a small plant with pinnae to 4.5 cm long. Price reports red young fronds on plants in Luzon but I have seen no such report from Java.
Dryopteris perakensis was based on Aspidium perakense BEDD., a species I could not account for and omitted from my book on Malayan ferns. I could not find a type in Kew herbarium, but some years later it was found, among other BEDDOME specimens, in the basement. It is based on an immature plant of Sphaerostephanos polycarpus mixed with a small fragment of a fertile pinna from another plant, an aberrant Christella. VAN ALDERWERELT VAN ROSENBURGH of course misinterpreted it.
