Distribution: — India, Indochina, southern China, western parts of Malesia (Flores, Java, Malay Peninsula, Simbawa, Sumatra), Thailand, and Australia (where it was once recorded from north-eastern Queensland by D. L. Jones s. n. (BRI), see: Bostock 1998). Note: — some specimens (Congdon 617, Molesworth-Allen 2785, E. Smith 250 A, Kerr 250, 11365) show unique leaf and spore characters that are similar but not identical with characters observed in other species of Calciphilopteris. It was decided to assign these specimens here to C. ludens, because available collections are insufficient to make unequivocal taxonomic assignments. These specimens may represent either a unique form of C. ludens or an undiscovered species.
